Is Nurturing Nature Necessary Or Does It Have Negative...

Is nurturing nature necessary or does it have negative consequences? In 1914, the last passenger pigeon, a bird that was catalogued at one time by famous ornithologist John James Audubon (who is still remembered through the Audubon guide series), died. There are and never will be any more. As a species, the Passenger Pigeon was hunted to extinction because they were noisy, messy, and disruptive. They would fly in huge (like blocking-out-the-sun type of huge) flocks, and one could imagine the towns that were flown over. In Charles Roth’s book, Then There Were None, he details how the extinction of an entire species was possible: the trees and forests (the bird’s natural habitat) were destroyed at nesting sites, which the passenger pigeon was very specific about, and the young were eaten, being more tender and palatable. Unfortunately, humans hadn’t learned yet the reach of their terrible destructive arm. Since everyone was eating the young and destroying forests, the picky passenger pigeon was not only old, they were also unwilling to lower their expectations for a nesting site. Therefore, no new pigeons were born, and there were no replacements for the elderly. Populations decline very quickly when there are no youth. As a result, the passenger pigeon is no more (Roth, 1977). What did we learn from this calamity? Well, according to the bison, beavers, wolves, mountain lions, bears, hawks, owls, ivory-billed woodpeckers, whooping crane, and black-footed ferrets, nothingShow MoreRelatedBilingual Education Has Many Advantages Essay1481 Words   |  6 Pagesprotection at old age from cognitive declines.

Changes, Changes and More Changes! Free Essays

Changes, Changes, and More Changes Hudson County Community College isn’t a perfect school, but there are a lot of things that they have room to improve on. I honestly don’t have many complaints about this school, I feel alright about it, I am not impressed but I am also not outraged by anything. Even though I don’t have many complaints about this school it doesn’t mean that I don’t feel that they have things that they should improve on. We will write a custom essay sample on Changes, Changes and More Changes! or any similar topic only for you Order Now The biggest problem I have with this school is the service at the main desk, then it would be the student lounge area, and last but not least the parking situation. These are all very important things to me, and these are things they should really fix. To begin, the issue of parking isn’t a big deal to me personally, but I’ve heard so many students and professors speak and complain about it that I think it’s high time something was done to fix the problem. For example, this is a college, which means that students ranging from seventeen years of age and higher, come to this school seeking a higher education. Most of these students have cars, but, this school doesn’t provide any parking for these students. So that means, that they must circle around the block about three times on a good day and about ten times on a bad day, until they find parking. Do you believe that’s fair? This causes students to be late for class and to miss important parts of the lecture. Now, on the other hand, teachers do have a parking area, but the parking is about ten blocks away, this of course isn’t a problem if it’s seventy to eighty degrees outside, but when the weather is cold, do you really think that people want to get out of their warm cars just to go out into the blistering cold, or when it’s 100 plus degrees outside, do you think people want to come out of their comfortably cool cars, and sweat in the New Jersey summer heat? Secondly, the lounge are. It literally is just a lounge area, with some vending machines thrown in. Imagine yourself a student who has been in class since, let’s say ten in the morning, and you haven’t had a good 45 minute break in hours, and you’re starving, so you walk down to the trusty student lounge and what do you find? You find a room with some chairs and a couple of vending machines, and not the cool kind of vending machines, that serve sandwiches or soups, but the kind that serve junk food. What would be your reaction to this? How would you feel in that instant? Of course, now you don’t have time to run down to the deli and buy yourself some lunch, because everything is so far away and you just wasted a good ten minutes coming down to the student lounge and staring at the vending machines in outrage. So what are you going to do? You are either not going to buy anything, or you’re going to settle for some chips and a sugar filled soda, a snack that is sure to make you crash in about twenty minutes. I honestly don’t see how this is fair, if you want student’s to do well in school, then you have to provide them with an environment where they can achieve success. Having to work through hunger and fatigue isn’t going to help them succeed. This school really needs a cafeteria, where students can go and eat something healthy and filling, not just a place where they can go and eat some sugar and sit for a couple of minutes. Lastly, the issue with the main desk. I’m not sure if those ladies know what their exact job is, but I’m sure that it’s not talking non-stop. I’m not saying anything bad about them, because they are extremely nice and friendly, but if they could be nice and friendly and do their job, now that would be super. I remember how my friend’s cousin, was having the biggest problem with finishing his financial aid paper work last year, it literally took him a year to finish fixing them, his little brother who was a year behind him in school, finished High School and started College before he did. That’s embarrassing. The fact that it took so long, the fact that he had to continue coming in to bring the same papers in almost every week, and the fact that he would get attitude and poor service every time, speaks lowly about the people working in those desks. I also had a problem like this, it didn’t take a whole year for me to fix my issues, but I did have to come in a bunch of times for the same problem, and to hand in papers that were later on not going to be useful in anyway. To the students of this college it is important that those women and men do their jobs, we need them, they fill up our papers, they send them to where they need to be sent, and they are supposed to make things easier for us, not the opposite, so to see that those people cause so much trouble for the students makes me think that this school has one major flaw, and this flaw can be easily dealt with. All they need to do is fire them and hire people who are more competent†¦ or if that’s too extreme give them a class where they learn exactly what their job description is, since it seems that they have forgotten it, or maybe never learned what it was. Changing some of this school biggest problems is sure to make this school become a place where other people would want to come and experience it, nobody wants to have a hard time at the main desk, or starve to death, or be late to class while looking for parking. The faster we solve these issue the faster we can start calling this establishment great, because as of now this is just a place where people come to pass the time and to get a taste of what college is like. This school isn’t perfect, but it’s imperfections really make people take a second thought to coming here, so the quicker we fix these problems, the quicker we can fill up the school with a lot of happy students and professors.

International Employment Relations Management-Myassignmenthelp.Com

Question: Discuss About The International Employment Relations Management? Answer: Introduction: This report gives emphasis on the employment relation which is concerned with France and Denmark. Employment relations have a direct connection with employers and employees who are working in the organization. Remuneration plays an important role which gives motivation to employees who are working effectively and efficiently. If in the organization the relation between the employer and employees is good then the company can easily achieve its goals and objectives in effective manner. The success and growth of the company depends upon the relations that are between the employees and employer of the organization. The working pattern of the company gives direct impact to enhance the growth of the business. In France the state give more consideration to the employers. Also the privatisation has played a great role which has a major concerned with different sectors. The France reflects much historical presence which is concerned with the labour movement and also has different reactionary approaches of employers. The state has various industrial connections which lack mutual cooperation between the social partners. The employers of France are united and also it has a high membership which exit by taking into consideration the practices of France (Bowman and West, 2015). Decentralisation is concerned with employment relations are enhancing but collective bargaining also plays a role at the national level. The coverage of collective bargaining is high if employment relation is taken into consideration. France is considered as the biggest economic power in which GDP is taken into consideration. The employment in relation with female is increasing and retention of school is also enhancing. In France there is no recession which has taken place but the economic growth is reduced. There are various forms of employment which has been changed by considering the international trends (West, 2015).The part time employment is increasing but it is on the temporary basis. In employment relation the state intervention is a major part of France. It gives direct reflection on the traditional reluctance which is related with the unions and employers. They take into consideration collective agreements and unions have applied for legislation. The close link is analysed between the industrial law and the results which are related with collective bargaining (Voorhoof and Humblet, 2014). Industrial law gives main emphasis of the collective agreements. The government of France has taken into consideration the corrective steps to minimize the unemployment which consider people who are young and also the people who are unemployed from long term (Bamber.G.J, Lansbury.R.D,Wailes.N and Wright.C. F,2015).In Denmark the role is very limited as compared to other countries but it is still very essential. The relations which are between the organizations and also the industrial conflicts are taken into consideration and the agreements are set between the parties. If consider state legislation then it is very limited (Campbell and Pedersen, 2014). The political interference is increasing day by day in France and it is mainly due to EU directives which have taken into consideration legislation. Industrial relation in France: The employment relation with France is considered as low social dialogue and also it has a great interference in the state. The French state not only plays a great role in employment relations but also have a great role as an employer. Just because of privatisation the government has the role in various sectors. In consideration with employment relations in France many labour movement and also collective bargaining has taken place on industrial level (Collins, 2011). It has a very important role which gives direct impact on the decentralisation with the help of socialists government that has given a very helpful role if politics and laws are taken into consideration. There are many reforms which give support to the workplace and also pursue equal objectives which give proper strategy to make legal obligations which are between the companies and also establish many self-supporting social dialogues which can take into consideration the labour market. An employment relation helps to giv e more focus on the decentralised combined bargaining. The employment relations concerned with France has a great impact on the legal and political environment of the country (Herriot, 2013). The employment rate for the people working is considered as 28 million in 2008 and the unemployment rate in France is considered as 7.8 percent in 2008. The people who are between the ages of 15 to 24 show the unemployed people who are 19 percent in 2008. There are many young people who are concerned about the economic fluctuation under the employment market. The rate of working women is high in France. The female labour market has taken enhancement from 37 percent to 52 percent in 2008 (Rodriguez, Johnstone and Procter, 2015.) Industrial relation in Denmark Denmark is considered as a coordinated market economy and also it has given emphasis to policy business development and coordination which has taken place on various network of trade unions and also given a major impact on the political administrative system. There are many regulations which have taken place in the collective bargaining and not in the legislation. Denmark is considered as a negotiated economy. The atypical employment levels are very less in Denmark. In consideration the employment in the public sector the enhancement is done effectively. The civil status has shifted to the contract which is done on the basis of employment level (Schtz, and Jacobs, 2014). The system of self-regulation Denmark also played an important role but it is only for limited area. In considering the labour market policy there are many employers who are associated with the councils and boards. The state has a main role in the IR as the employer which is concerned with the public sector. If labou r market policy is taken into consideration then the state can take step to consult with union and also the employer who has a direct connection on councils, boards and commissions. It plays a great role in industrial relation that is concerned with employer in the public sector (Lakhani, Kuruvilla and Avgar, 2013). Comparison If the comparison is made between France and Denmark it is seen that the France is the weakest when it is taken into consideration with Denmark. It is the combination of trade unions and employer association. Trade union gives emphasis to secure the working conditions which refer that the member that is concerned with the member of the trade union is very common in Denmark and also gives many services which they want. Trade union gives much guidance and also legal support which gives main focus to the contract which is based on employment like salary and the problems which is related with work injuries. Denmark has a score of 7.8 and France has a score of 7.2 in the differences which are made from country to country and which give focus to the government regulatory (Valizade, Ogbonnaya, Tregaskis and Forde, C., 2016). By law the freedom of association consist of military and police but in France there is only freedom of association. The minimum working age is 15 in Denmark but in Fra nce the minimum working age is 16. In Denmark the proportion of trade union in workforce is 75 percent but in France the proportion of trade union in workforce is 8 percent. The minimum annual holiday which is allowed is 25 days in France but in Denmark the minimum annual holiday which is allowed is five weeks including the public holidays. Union which have the right to strike but they consider it on frequent basis in France but in Denmark union have the right to strike except the essential services and by the civil servants. In Denmark there is no statutory minimum wage but it is only focused on collective contracts but in France there is a statutory minimum wage (Bamber.G.J, Lansbury.R.D,Wailes.N and Wright.C.F.,2015).Denmark gives focus on collective agreements and also covers 85 percent of workers but in France it gives focus on multi-level contracts which cover 90 percent of workforce (Noe, Hollenbeck, Gerhart and Wright, 2013). Overview of France and Denmark The Denmark and France relations are concerned with the current and also historical relations that are between France and Denmark. Denmark has many embassies; that has an embassy in Paris and the France and also has an embassy in Copenhagen. The two countries are the members of NATO and also of the union which is concerned with European. The relations which are concerned with the Denmark and France have the middle ages. Now a days Denmark has developed a very competitive and also a service which is based on the economy with the high level of employment and also with a social security system. Denmark is also called a happy place to live. The standard of living is high in Denmark and the country has a high score in the national performance which consists of education, health care and also human development (Poole, 2013). The country has a high rank in the mobility which is concerned socially and also has a high level of equality in income. France is known as one of the largest country in EU which has a connection with north and sea Mediterranean. It has a feature that gives focus to the reflection on the contemporary union and also on the historical existence and give emphasis on the approaches which are concerned with reactionary. The state has a strong role and also it has a multi system of the employee representation which is between the organizations. There are many strikes which are reducing and also it is giving a major impact on the public sector in the short run. France is considered as the largest and also sixth economic power in context with GDP. There are many low growths in context with GDP and also there are no severe recessions. The unemployment has increased and also it has given results which are concerned with schemes of training. There are various forms of employment which has changed in line and that are concerned with the trends and are focused internationally (McDonald and Thompson, 2016). The French unions also have a traditional militancy w hich gives enhancement to the strikes and political actions rather than giving recruitment to a mass which is related with the membership and also which engage in collective bargaining. The wages which are concerned with union wins and also if they dont have the members who are related with unions. There are no specific benefits which are concerned with welfare. It gives the impact on the French unions that perform tasks in other countries (Crane, LeBaron, Allain and Behbahani, 2017). Dispute settlement and State Mechanisms The disputes between France and Denmark take place and also the war which has taken place involves the union. The Sweden also takes into consideration France which was against many European countries. The war does not have any definite victory and also the Swedish navy vanished at sea. By considering the Danish army it was defeated in Scania by the Swedes and also it was defeated on the northern Germany. The war has taken place and was completed when the provinces which are related with the united was settled in effective manner by Denmark. Peace was made in effective manner on behalf of the France with a combination of saint Germaine who has given various lost territories to Sweden. Also the cooperation was enhanced and considerable measures are taken into consideration without involving the other members of the union (Dau-Schmidt, Finkin and Covington, 2016).The right to solve the conflict is taken into consideration to renew the contracts which are related with the existing collec tive contracts. The disputes are resolve by the mediation which has involved state conciliation board. The biggest conflict which is in public sector was held in 2008 in relation with health and care for the kinder garten sector. There are many local disputes which have taken place by many strikes which are unofficial and it has minimized recently (Dubin, 2017). The labour law system resolved many conflicts but conflicts are also taken in the labour court. There are many changes which are related with collective bargaining and with the labour market which has regulation in Denmark and also it has revealed many challenges which are faced by the Danish model. The labour market keeps the strong self-regulation and also enhanced the political control (Gillet, Gagn, Sauvagre and Fouquereau, 2013). Recent changes to IR and its factors: In France there are many changes which has taken into consideration. The industrialisation and also urbanisation has taken place in 19th century and also it has taken into consideration many factors that were in legal form. There are various informal unions which were organized at the local level and the state that has a great role in interventionist and the employment relations has enhanced in effective manner. There was enhancement in the attitude of the employer and it has also enhanced the French employment relations (Sanders, 2017).The revolutionary socialists which is within the French labour movement also combined the attitude of the employers which has given enhancement in the development of the employment relations and it has also explained the lack of mutual recognition which is between the IR parties and also this state has played a major role in enhancing the employment relations(Fossum, 2014). The France union has given and enhanced the financial and organizational resou rces and the membership which is concerned with union has been declined. In France the employment relations are also maintained in effective manner. The benefits are also given to pensioners. The retired people are offered pension according to the work which is performed by them. In Denmark the crisis also occurs which is concerned with economy. The crisis also distorted the balance of power between the social partners and also it has inclined to the outcome of bargaining. Also in Denmark many industrial relations and the conditions which are working has given support to the network of the correspondents. The employment relation in Denmark has enhanced the working capacity of the workers and employees and they now focus on achieving goals and objective in effective way (Donaghey, Reinecke, Niforou and Lawson, 2014). The workers who are working in France have a flexible working time just because they focus on attaining the work life balance. It also gives permission to the employees to participate in education or in training in which they are interested. It clearly states that the workers can easily manage their working hours easily by taking into consideration their weeks, months or even years. Also there are many changes which have taken place by national economic planning agency that the working time should be properly managed with the people demand and also the life of people should be considered. It has given positive impact on the life of employees who are working in France. It has also increased their working structure and enhances their level of motivation. Conclusion It can be easily analysed that the employment relation between Denmark and France is efficient enough. The employment relation has given a positive impact on the state. It has also enhanced the efficiency of the employees who are completing their task in effective manner. There should be proper employment relation in the company then only the company can enhance its growth in the market and can achieve goals and objectives in effective way. For creating goodwill in the market the company should take into consideration an effective employment relation which enhances the image of the company. The company gives main emphasis on maintaining the relations of the employees which gives empowerment to other employees to give their best so that they can easily achieve the objectives in effective way. There are many regulations which are taken into consideration by both the states which enhances the level of satisfaction of the employees. Denmark and France both plays a great role in maintaini ng employment relation in effective way so that the employees can conduct and complete their task in effective way.

Demise of Mongols essays

Demise of Mongols essays The Mongols were nomads, people who depended mainly on livestock for their livelihood. They were constantly on the move in response to seasons and searching for better grazing for their herds. This moving about also created opportunities and channels for trade with the different peoples and cultures with whom the Mongols came in contact. The Mongols themselves traded for commodities that they did not produce but needed iron being a good example. They also traded with agricultural people to obtain grain, vegetables, cotton and silk. This simple economic structure of the Mongols was inadequate to support the vast empire that the Great Khans had created during the 13th century. As the Mongols united nomadic tribes and expanded across the steppes of Asia and into the Middle East, Russia and China, they relied on resources taken from the acquired lands and societies to sustain their armies, infrastructure and other needs. Basically they took the wealth from others and used a system of harsh taxation to meet the rising costs of the empire. On the one hand the Mongols promoted economic development by opening up trade routes and permitting a freer flow of goods from one region to another, while on the other hand they were an economic burden to the societies they controlled. The Mongols were also inclusive, bringing captured people (at least those they did not kill or enslave) into their empire. This practice let them magnify their success by acquiring more people and armies but also stretched their Mongol leaders very thinly over a huge territory. So while the Mongols created unprecedented commercial integration and controlled a huge land area, they financed their empire by imposing heavy taxes and plundering they were wealth takers not builders. Similarly, while they brought together many peoples they had no common system for administration as had the Romans or the Greeks. Thei ...

Going for growth by investing in people, products and plant 2 Essay

Going for growth by investing in people, products and plant 2 - Essay Example Question 1 Before making an investment, it is prudent that one possesses an effective understanding of the market of operation. This is important in making an informed investment move. The process of studying the market and developing an understanding of the same is collectively referred to as investment appraisal. It involves a series of market evaluation through a number of mechanisms which result in the comparison of the business’ key objectives which are profitability under the existent market forces (Willey, 2012). There are a number of investment appraisal methodologies including net present value which investigates the ability of the market to repay the investment given the numerous present market factors such as inflation. One of the most preferred of these methods is the direct payback method in which the investor calculates the number of years it may take the business to return the initial investment. Some other investment appraisal method is the accounting rate of r eturn which bases its assessment of the market on its ability to earn profit to the investment. Despite their different approaches to the appraisal, the methods safeguard the interest of the business by trying to determine its profitability and above all its longevity. The life of a business is of great importance to the investor since the longer a business stays viable, the more the investor earns. The company makes an extensive capital investment with the sole aim of achieving the business objective. Capital investment is the amount of money that the enterprise invests in fixed assets which are directly used before implementing its investment plan. In this case, the Hazelwood Sandwiches Company carries out an extensive market research and investment appraisal thereby ensuring that their company stays relevant in the evidently dynamic market (Tabbush, 2011). This includes enhancing the production process such as the machinery and the production plant. The company does this after st aying in operation for some time; it therefore has an understanding of the market. Its decision to make such an expansive capital investment arises from the understanding that it has for the market. The company, just as any other desires, to stay active in the industry for as long as it takes. It therefore collects adequate information about the market and has its market facts right (Thomas & Michael, 2001). After determining the market size, the company determines its market share which is indeed the largest. The subsequent investment therefore arises from the desire to retain the position thus safeguarding both the profitability and the longevity of the company. The company has therefore mapped out its capital investment plan in phases to ensure that it does not become bankrupt in the process since such as scenario might have stifled the production process thereby either incurring debts or resulting in the eventual closure of the company. While purchasing fixed assets and improvin g the scale of production, the company also increases its working capital which is also part of capital investment. Question 2 The investment decision technique is synonymous to the investment appraisal method. The three discussed in the article are the playback method, the net present value, and the account rate of return (Alexander, 2010). Despite the fact that they all lead to an appropriate investment decision, they are different in their provisions and therefore possess unique advantages and disadvantages. The net

High Housing Prices in Shanghai Essay Example for Free

High Housing Prices in Shanghai Essay The topic of my presentation is making analysis into three parts—current situation, cause and solution. The first part—current situation. Now, many experts still believe that housing prices continue to rise; just because of limited land. The range of rise in housing price exceeds the range of rise in resident income. It makes lots of low and middle-income people worried about their own houses. Housing revenue rate is increasing, so real estate plays an important role in the economy of Shanghai. The first cause isThe economy of Shanghai continuously rise and it makes real estate market prosperity and development. From this chart, we can find a trend—GDP in Shanghai increased every year. People have more and more money to invest. In addition, Chinese have a traditional view that buying houses is the best way to keeping value. The second point is huge profits. Along with the change of industrial structure, many people find real estate industry has huge profits in China. In China, its average profit rate is 69% and gross margin is as high as 55%. Huge profits attracted more businessmen and speculators. The third point isBanks have launched mortgage. Mortgage has brought a great hope to someone who can’t afford to buy a house. This table shows housing loans occupy very large proportion of personal consumption. And in 2004, the upward trend appeared, at the same time, Shanghai housing loans reached 244 billion Yuan. The forth point isPopulation movements. It is a common sense that Shanghai is an international city, citizens come from different places. The picture below tells us a mode of population movements. Demands are more than supplies which means population is becoming bigger and land is becoming limited. That’s why Shanghai housing prices will continue to rise. Next, The first solution is Low-rent Houses. The government should increase investment to support poor people. The low-rent housing can meet basic requirements for them. This method will solve the social problem due to high housing prices and enable social stability. The second solution is Strengthening supervision. Each functional department should crack down on illegal real estate developers and illegal development behaviors. Actually, the government should restrain overheat and high housing prices. The third solution is Revising and improving relevant laws and regulations. Laws and regulations will standardize the real estate industry and its market to eliminate the cause of huge profits. And it will also standardize housing prices and taxes. In this way, many illegal businessmen and speculators will be sued reasonably. The forth solution is Correct media publicity. Making correct investment guide for consumers to avoid invest huge money on real estate blindly. Absolutely, it is a best way to sound an alarm bell for illegal businessmen and speculators to make them awake. Finally, I will summary my essay. Real estate is the first-class important event in the common people life. High housing prices problem must be solved as soon as possible.

Hamlet: Power vs Happiness :: Shakespeare Hamlet Essays

Claudius what are your motives for killing the king, marrying his wife and taking on the role of father to his young son?      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Claudius is introduced in act I, ii.   In this scene he has an important speech. In this speech he talks about the death of the king, his marriage to the queen and the foreign problems of the state. He utilizes many transitions and tends to empiseze the foreign affairs of the state. I don't know what to make of this, it could mean various things. It could mean that Claudius is making a grab for power shown in his concentration on the foreign polices trying to distract from his lust for power, along with his marriage to the queen giving the change in leadership a smoother and more acceptable feel. He also down plays the death of the formal king so that he can redirect the peoples' attention to his plans and the problems of the state. But I could mean something else I'm not sure. Later on in this scene Claudius talks to Hamlet, Hamlet is very depressed, Claudius gives hamlet some comforting and fatherly advice here trying to get him out of his deep depression. But what is his true motivation here is he trying to get hamlet as a backer for his new rain, so he is just   lying and manipulating hamlet, or dose he have true and deep feelings for Hamlet and is just trying to help hamlet and was no self-interest in it. I feel right now that   it a bit of both I think   he cares about hamlet but would also like him to support his rise to power.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Next we come to act II, ii,   hamlet has made many strange comments and actions lately, many people think he is going, or has gone insane. Claudius finds two of Hamlets good friends to spy on him and try to find out what wrong with him. At this point we know that Hamlet knows that Claudius killed his father but we don't know whether Claudius knows that hamlet knows or even if he suspects, this cast a strange light on this scene. First if Claudius suspects hamlet knows that he killed his father then we might assume that Claudius is sending these spy to find out for sure if he knows, but if he dose not suspect hamlet then this might be another show of Claudius's affection towards Hamlet. So the same question keeps coming up dose Claudius like Hamlet or is he just using him? At this point it to hard to tell so we must delve deeper in to the

Mitosis Replication of Eukaryotic Cells

Exercise 13MITOSIS: REPLICATION OF EUKARYOTIC CELLS  ANSWERS TO QUESTIONS1.a. Mitosis and cytokinesis are often referred to collectively as â€Å"cellular division. † Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided.b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and end, but the events continue to repeat.2.a. If a nucleus has eight chromosomes during interphase, how many chromosomes does it have during metaphase? During metaphase there are 8 double-stranded chromosomes.b. How many does it have after mitosis is complete? After mitosis (and separation of chromatids) there are 16 chromosomes distributed between two nuclei.3.a. Why would we choose an embryonic mass of cells for procedure 13. 3 in which to study the stages of mitosis? embryonic cells a re replicating and growing rapidlyb. Which stage of mitosis most often is associated with the beginning of cytokinesis? usually late anaphase4.a. What region of a root has the most mitotic activity? meristem, just above capb. Why is pinching of the cytoplasm inadequate for cytokinesis in plant cells? Pinching of cytoplasm is not appropriate for rigid cell walls.c. Locate a plant cell in late telophase. What is the volume of the new cells relative to a mature cell? Each cell is smaller (approximately 1/2) than the parent cell.5.a. Why are the combined data from all the class members more meaningful than your results alone? Combined results reduce random error.b. How accurate were your predictions for length of each stage of mitosis? probably not closec. What sources of error can you list for this technique to determine the time elapsed during each stage of mitosis? ariation in onion roots; student's ability to distinguish stages; microscopic cross sections of roots may or may not pas s through the nuclear materialExercise 14MEIOSIS: REDUCTION DIVISION AND GAMETOGENESIS ANSWERS TO QUESTIONS1. a. Why would shuffling genetic material and producing new combinations of characteristics be advantageous to a species? New genetic combinations allow adaptation to changing environments.b. When would it be deleterious? New combinations always produce a percentage of disadvantageous characteristics; the risk of bad gene combinations may be inappropriate in a stable, beneficial environment.2. a.Synapsis occurs after chromosomal DNA has replicated. How many chromatids are involved in crossing-over of a homologous pair of chromosomes?b. Suppose synapsis occurred between two homologous chromosomes, and one had alleles for blue eyes and brown hair and the other had alleles for green eyes and blonde hair. How many different combinations of these alleles would be possible? 4 Remember that crossing-over does not necessarily occur between the loci, so the original combinations may re main intact. 3. a. If a nucleus has eight chromosomes when it begins meiosis, how many chromosomes does it have after telophase I? Telophase II? with two chromatids each; 4 with one chromatid eachb. What are the major differences between the events of meiosis and mitosis? (see table 14. 2)c. What are some minor differences, and why do you consider them minor? minor differences would be those unrelated to chromosomal events4. a. During gametogenesis a sperm cell undergoes considerable structural change. What are the basics of sperm structure and how does it relate to function? The basics include small head with nucleus; an acrosomal process with enzymes to digest the outer membranes of the egg; a head and neck rich in mitochondria; and tail used to propel the cell to the egg.b. What is the advantage of producing sperm in a system of tubes rather than in solid tissue? because sperm cells can be expelled easily from the body through a system of tubesc. What is each strand of a double-s tranded chromosome called? chromatid5. How would retaining extra cytoplasm enhance survival of a developing oocyte? More cytoplasm contains more nutrients to ensure survival.6. a. What are the relative sizes of oocytes in a dormant follicle, a growing follicle, and a Graafian follicle? dormant oocyte 1X, growing oocyte 5X, mature oocyte 25Xb. Are polar bodies visible in your prepared slide of a cat ovary? Why or why not? probably not, because cells in the ovary usually have not finished meiosis I, and polar bodies disintegrate rapidly DNA FINGERPRINTING LABRestriction Digestion of DNA Samples Observation QuestionsDescribe the samples of DNA (physical properties). The DNA samples are clear, colorless liquid samples.Is there any observable difference between the samples of DNA? No. All samples appear similar.Describe the appearance of the restriction endonuclease mix.

Explain. No. No visible change apparent in the tubes.In the absence of visible evidence of change, is it still possible that the DNA samples were fragmented? Explain your reasoning. Yes. They may be chemically changed but the changes may not be visible. Enzymes may have cut the DNA.After a 24 hour incubation period, are there any visible clues that the restriction enzymes may have in some way changed the DNA in any of the tubes? Explain your reasoning. No. No visible change apparent in the tubes but the enzymes may have cut the DNA. The reactions are at the molecular level and too small to be seen.Electrophoresis of Your DNA Samples Review QuestionsThe electrophoresis apparatus creates an electrical field [positive and negative ends of the gel]. DNA molecules are negatively charged. To which pole of the electrophoresis field would you expect DNA to migrate (+ or -)? Explain. Positive.What color represents the negative pole? Black.After DNA samples are loaded in wells, they are â€Å"forced† to move through the gel matrix. Which size fragment (large vs small) would you expect to move toward the opposite end of the gel most quickly? Explain. Smaller. There is less resistance to their movement through the gel matrix.Which fragments are expected to travel the shortest distance [remain closest to the well]? Explain. Larger. There is more resistance to their movement through the gel matrix.Lesson 4 Thought QuestionsWhat can you assume is contained within each band? DNA fragments.If this were a fingerprinting gel, then how many kinds (samples) of DNA can you assume were placed in each separate well? One.What wo uld be a logical explanation as to why there is more than one band of DNA for each of the samples? The DNA must have been cut into fragments by restriction enzymes.What probably caused the DNA to become fragmented? The chemical action of the restriction enzymes cutting at specific base sequences.Which of the DNA samples have the same number of restriction sites for the restriction endonuclease used? Write the lane numbers.Lanes 2, 3, and 4 (CS, S1, and S2).Which sample has the smallest DNA fragment? The sample in lane 5 (S3).How many restriction sites were there in lane three? Two sites that cut the sample into two fragments.Which DNA samples appear to have been â€Å"cut† into the same number and size of fragments? Lanes 2 and 4 (CS and S2).Based on your analysis of the photograph, what is your conclusion about the DNA samples in the photograph? Do any of the samples seem to be from the same source. If so which ones? Describe the evidence that supports your conclusion.The DN A samples in lanes 2 and 4 (CS and S2) are from the same individual because they have identical restrictions sites that yield identical fragments.DNA Fingerprinting: OverviewWhat are we trying to determine? Restate the central question. We are trying to determine if samples of DNA that we were provided with are from the same individual or from different individuals.Which of your DNA samples were fragmented? What would your gel look like if the DNA were not fragmented? The number of fragmented samples will vary. They will have one band on the gel if the DNA was not cut.What caused the DNA to become fragmented? The addition of restriction enzymes.What determines where a restriction endonuclease will â€Å"cut† a DNA molecule? A special sequence of bases on the DNA called restriction sites.A restriction endonuclease â€Å"cuts† two DNA molecules at the same location. What can you assume is identical about the molecules at that location? The restriction sites are identical .Do any of your suspect samples appear to have EcoRI or PstI recognition sites at the same location as the DNA from the crime scene? The samples in lanes 2 and 5 match (CS and S3).Based on the above analysis, do any of the suspect samples of DNA seem to be from the same individual as the DNA from the crime scene? Describe the scientific evidence that supports your conclusion. The CS and S3 samples appear to be identical. They both produce similar banding patterns on the gel.Exercise 23 SURVEY OF BACTERIA: KINGDOMS ARCHAEBACTERIA AND BACTERIA ANSWERS TO QUESTIONS1. a.
