The Process Of Cell Division In Animals Coursework

The Process Of Cell Division In Animals - Coursework Example The cell cycle comprises of four important stages. S stage is for synthesis and DNA replication occurs in this stage. G2 comes after and S phase and is the phase of DNA repair and correction of any mistakes made during DNA replication. Only the cells with repaired DNA are allowed to enter the M phase. M phase or mitosis is when nuclear and cytoplasmic division occurs culminating in the formation of daughter cells. Cytokinesis is the cytoplasmic division of the parent cells. When a fibrin ring called actin contracts around the center of the cell, it leads to pinching of the cell into two daughter cells, each containing one nucleus. Interphase is not technically a part of mitosis as it is the phase in which the cell is metabolically prepared for mitosis. Chromosomes are not clearly distinguished and the pair of centrioles starts appearing. 5. Suppose someone presented data from their research that showed the DNA of a newly discovered species was composed of: 30% adenine, 30% guanine, 2 0% thymine, 20% cytosine. Based on what you know about DNA structure, explain why these data do not make sense. The Chargaff’s rules indicate that the amount of adenosine equals the amount of Thymine and the amount of Guanine equals the amount of Cytosine. Therefore, the total purines equal the total pyrimidines. However, the rules only apply on double-stranded DNA or double stranded RNA and single stranded nucleic acids such as in viruses do not follow the Chargaff’s rule. The data presented shows 30% adenosine and 20% thymine, and 30% guanine in comparison to 20% cytosine. This data contradicts the Chargaff’s rule, indicating that it is not a double-stranded nucleic acid and most likely represents the base pairing of single-stranded nucleic acid, maybe in viruses. 6. What are the differences between a covalent bond and an ionic bond? In a covalent bond, the atoms are bound by the sharing of electrons. The electrons are shared either equally or unequally betwee n the two atoms. If the electrons are shared equally between the two atoms, the covalent bond is said to be non-polar. If the electron is attracted more towards one atom than another, it leads to the formation of a polar covalent bond, for example the molecule of water H2O. In contrast, the ionic bond of two atoms is formed by the forces of attraction between oppositely charged ions. For example, NaCl is formed by the positively charged Sodium (Na) atom and the negatively charged Chloride (Cl) atom. 7. Water is crucial for life as we know it. One of the most important characteristics of water is its ability to act as a solvent. Explain why water is such a good solvent for polar and charged molecules. The physical and chemical composition of water makes it a very good solvent for polar and charged molecules. Water molecule is made up of positive electrical charge of Hydrogen atoms and the negative charge of Oxygen atom. This forms a very strong polar covalent bond and contributes it a property of being a good solvent, by disrupting the attractive forced between other charged molecules. The polar molecules are easily dissolved in water because the forces of attraction are disrupted between the solute. The positive charges are attracted towards the negative Oxygen pole of water and the negative charges of the solute are attracted towards the positive Hydrogen pole of water. The atoms of solute are then surrounded by water molecules, making it a good solvent for charged and polar molecules. 8. Suppose you are taking a cruise from California to Hawaii. About halfway there, the ship begins to sink. You are able to board a lifeboat, but now you are floating in the ocean waiting to be rescued. After several days, you are so thirsty that you bend over the side of the boat and drink

Consumer Protection Act Case Study

Consumer Protection Act Case Study This case study concerns the liability of a manufacturer of a product for harm which is suffered by the â€Å"ultimate consumer† of that product. It is important to consider the remedies that would be available in contract and under the doctrine of tortuous liability for defective goods. There is privity of contract in the relationship between Pamela and Cooks Stores and, therefore, in contract a remedy would be available to Pamela only. To invoke such a remedy under contract, Pamela should be able to rely on the terms implied into the contract by the Sale of Goods Act 1979, such as provided under s. 14 (2B) by which goods are not of satisfactory quality if they are unsatisfactory in terms of safety and durability, according to the standards of a reasonable person. The SGA provides recourse to a seller and, therefore, this act should enable Pamela to reclaim the  £175 purchase price of the food processor from Cooks Stores. According to the â€Å"narrow rule† in Donoghue v Stevenson a manufacturer owes a duty to the customer to take reasonable care when he sells goods in the form in which he intends them to reach the ultimate consumer with no reasonable possibility of intermediate examination. This rule is a variety of negligence and creates a regime of fault-based liability on the part of manufacturers, which will include retailers, such as Cooks Stores, alongside Price (UK) Ltd. Both Pamela and Rose are potential claimants since here they are both â€Å"ultimate consumers† and the rule covers those who receive goods as presents and bystanders. To bring an action in tort Rose, as the claimant, would have to show the existence of a duty of care, breach and causation. Rose might have a cause of action against Price (UK) Ltd as manufacturer, if she can show that there has been a failure in the production process, for instance. The doctrine of res ipsa loquitur may be useful here, as developed in Scott v London and St Katherine Docks Co., which, it has been argued, creates a rebuttable presumption of negligence on the part of the defendant. Following Erle CJ Rose would have to show that the accident was of the kind that does not normally occur in the absence of a want of care, that the defendant had exclusive control over the thing which caused harm and that the defendant cannot offer any plausible alternative explanation of what caused the accident. Although these would be evidential questions, they might help Rose to determine whether or not Price (UK) Ltd has breached its duty of care, which is important since experts are unable to identify the precise reason for the incident. It is important to consider the possibility of intermediate examination and whether Rose was using the food processor properly. While it is stated that Rose followed the operating instructions carefully, it should be noted that Pamela has used it previously – if not frequently – without difficulty. This leaves open the possibility that consumer misuse is at the root of the problem. Further, the manufacturer might be exonerated if another person can reasonably be expected to inspect their product. From the facts as presented it is unclear whether the food processor could reasonably be subject to an intermediate investigation, as was argued unsuccessfully by the defendant in Grant v Australian Knitting Mills. If this reasonable expectation arises the tester could be regarded as the cause of the harm, and therefore, Cooks Stores might be found to have contributed to the negligence of Price (UK) Ltd. It is, however, unclear whether a retailer can reasonably be expected to test every appliance that it sells. This defence would be unlikely to allow Price (UK) Ltd. to deflect all the blame on to Cooks Stores. The burden of proving the causal link between any breach of duty by Price (UK) Ltd and/or Cooks Stores and the harm suffered by Rose rests with Rose herself, as confirmed in Foster v Biosil. Should she fail to satisfy the burden of proof in this respect, her action will fail. Should Rose be successful, following Aswan Engineering she would be able to recover â€Å"non-integral† damage caused by the defect in the food processor, such as the vase. She would also have a claim for loss of amenity in respect of the personal injury to her hands and face, with a quantum to be evaluated. The regime introduced by the Part I of the Consumer Protection Act (CPA) 1987 would provide Rose with an alternative, since it purports to create a system of strict liability in respect of defective products that cause physical harm to a person or property. The CPA 1987 makes a producer, i.e. Price (UK) Ltd., responsible for the defectiveness of their product, however, according to CPA 1987 s. 3(1) regard may be had to any warnings which had been provided. The status of any such warning remains unclear. The CPA 1987 s. 3(2) allows a court to consider how a product might reasonably be used. It remains to be seen whether Rose was using the food processor for the correct purpose, even if she was attempting to follow the instructions. It is clear from CPA 1987 s. 6(4) that the defence of contributory negligence will apply to a defective product and any damages awarded to Rose may be reduced dependent on her blameworthiness. The CPA can be invoked against anyone involved within the chain of manufacture and distribution and liability is joint and several, so Rose would be best advised to sue whoever has the greatest financial resources. Cooks Stores, as a supplier, is however only liable to name their supplier and, accordingly, Price (UK) Ltd. will be Rose’s target for any damages. The CPA covers personal injury, but no damage to property under  £275 and, therefore, under the guise of this act, Rose would be unable to claim for the damage to her vase and would be advised to rely on tort.

Auto Industry Structure and Resources Essay

According to Taylor (2012), profits are going to be derived from a handful of mega-companies in North America, Europe, and Asia. These companies include General Motors (GM), Ford, Toyota, Volkswagen, Renault/Nissan, Hyundai/Kia, and Fiat/Chrysler. The chart below, taken from Taylor’s article, demonstrates global sales of auto makers in 2011 and what is predicted to be the companies’ global sales in 2020. (Taylor 2012). This chart reflects which auto makers are at the top in terms of sales, so this could also be interpreted as the companies that are the strongest within the industry. An industry is a group of firms that market products which are close substitutes for each other. Some industries are more profitable than others due to the dynamics of competitive structure of an industry. There are basically five forces that determine the long-run profitability of an industry; threat of entry of new competition, threat of substitutes, bargaining power of buyers, bargaining power of suppliers, and degree of competition (Porter, 2008). Many companies within the United States and world may look to the automotive industry as a possible â€Å"cash cow. This is due to the large inelastic demand followed with a hefty pay off per sale. As a company interested in entering the automotive industry competition, one may find that it is easier said than done. Since 1860, there have been over 1,800 manufacturing companies that have entered into this competitive market within the United States. Of those 1,800 manufacturers, over 760 have gone out of business, leaving a success rat e of less than 57% (Georgano, 2000). Entry into this manufacturing arena requires a huge down payment. Procuring machinery, personnel, factories, and raw materials can put a multi-million dollar price tag of investment and overhead before one sale is completed. Before these complicated pieces of machinery start rolling off the production line, sales strategies and logistics need to also be considered sinking more overhead and investment into start up costs. For the manufactures that decide to exit this market, there is a large sum of invested money and jobs that are lost. In many situations, losing such a large degree of sunk costs in a plant closure tends to become the precursor to company bankruptcy or selling off of the company. The excess inventory, machinery, and other assets will need to be sold off to try to maintain survival of the existing company. If the company has debt, income from selling off assets or the bankruptcy will be utilized to pay these debts. Either way, exiting this market can cause great financial drain and costly repercussions of the company’s financial livelihood. In recent years, more manufacturers have taken the financial risk on and been able to enter into the market. The automotive market structure began as an oligopolistic structure due to the limited vendors. In this system, several large sellers have some control over the prices. As time progresses and more domestic and foreign manufacturers enter into the competition, a more perfect competition (many buyers and sellers, none being able to influence prices) is emerging (Business Dictionary. om, 2012) reducing elasticity within the market. Education and training, wages, and technology are three major factors which impact the quantity and/or skill level of the labor supply in the auto industry. In reviewing the labor supply, we will divide the industry by business and front-line workers. These two general groups would require great variance in education and skill; therefore, the potential labor supply for each should be reviewed separately. The front-line workers in manufacturing, production, and sales of the auto industry generally require minimal education and receive on-the-job skill training. These workers may have a high school diploma and great variance in skill level for manufacturing and sales. They will receive the training needed on the job and their wages will not greatly vary; therefore, the effect of changes in training and wages for those workers of the industry would be considered minimal in changes to the supply curve. For this group, advances in technology would have a greater impact. In reviewing the labor supply for the business segment of the automobile industry such as business management, engineering, and marketing, this is the population of the industry which must: understand and keep track of changing consumer demands, understand how to maximize opportunity for growth, how to forecast, how to market, and be innovative in design and features of automobiles as technology continues to advance and the market remains competitive. According to the Consumer Population Survey (CPS), in 2011 the U. S. Labor Force, age 25 and older, with only a high school education made up over three and a half million potential laborers; while in the same year, those unemployed with a college degree equated to around two million (Bureau of Labor Statistics, 2012). Therefore, the total labor supply for the industry was nearly six million with varying skill levels. The auto industry was hit hard during the recession and is still coping with large structural changes. Over the past couple of years, the automobile companies have closed plants and discontinued brands and they downsized, restructured and cut budget to bring costs more in line with sales. They also cut jobs, as many as 300,000 or more according to some estimates. Recently, the profits of the auto industry have turned around and they are, again, making profits. There is now a shortage of workers with the right skill-set. The challenge is finding the right workers with the right skills needed by the workers in the industry, especially as more teams work globally. Because of the new technologies and operations, so called â€Å"un-skilled† workers are rarely needed now. The workers also need problem solving skills and decision making skills. Creating a workforce with these abilities requires a different approach by the human resources team. Better workforce planning is essential to creating the right fit. Automakers are turning their attention to building automobiles that either rely less on traditional fuel sources or use cheaper renewable sources of energy. These â€Å"green† solutions will attract consumers. As automakers are turning their attention to new technology, their talent must be able to grow with them. The shift in consumer preferences in the auto market towards hi-tech, fuel-efficient and environmentally friendly vehicles is a significant challenge to the industry. Auto manufacturers and suppliers will have to adapt quickly to the new technology and invest in research and development. Globalization has also put pressure on the auto industry and its traditional workforce. The future demand will be that auto companies have a flexible workforce that can constantly learn and refresh its skills. The workforce must be able to be flexible and the industry must leverage rapid learners and be able to re-train employees and re-design jobs. This will be costly for the automobile industry but will be needed to be successful and beat the competition. There may not be a need for the unskilled worker in the auto industry, but there will always be a need for workers. Their roles will change to keep up with the technology and changing markets. Steel, plastic, aluminum, rubber, and glass are the top five materials used in the automobile production process (George P. , 2012). While some of these materials are derived from a natural resource which could potentially pose risk on quantity, such as steel from iron ore and rubber from petroleum, there are forms of either synthetic or renewable resources for each as well as the ability to recycle all of these materials for reuse. None of these materials are of precious minerals and there are no real variances found in quality of such materials. For example, recycled steel, aluminum, and glass can be used in automobiles because they can be recycled indefinitely without losing their properties (RubberAsia, 2009, Hincha-Ownby, 2010, and Blue, 2012). Historically, the automotive and construction markets have remained the largest consumers of steel, with more than half of the steel produced. Over the past few years, China has emerged as the major consumer of steel, with the U. S. ext, followed by Japan. In 2008, the steel industry suffered a decline due to the recession. This was seen by consumers buying existing inventories of vehicles rather than buying new stock. The industry turned around in 2009 and continued to grow. Replacement tires are the second highest operating expense for commercial fleets, next to fuel (Automotive Fleet, 2011). In 2010, the cost for tires in the passenger car segment was up 11%. Almo st 60 percent of the world’s rubber is consumed by the global tire industry. China is the world’s largest rubber consumer

Travelling Troubles

Traveling is widely believed to broaden the mind and enrich the soul. The famous saying â€Å"Don't tell me how educated you are, tell me how much you have traveled† indicates that travel can enlarge people’s knowledge efficiently. Many people believe that when you visit other places you experience new things and learn from them. To my mind, it’s impossible to imagine our life without traveling. Getting out of the place where you always live, then going to an unfamiliar place is a kind of unforgettable experience in your life. First of all traveling is visiting interesting places and meeting new people.It is connected with getting to know other cultures and traditions. Secondly, it is usually said that journeys educate, so traveling we can make our knowledge wider. Also we become more experienced and ready to cope with surrounding world if we learn something while being in journey. Furthermore, traveling is a psychological necessity, especially for people who hav e stressful jobs. There are people who do not want to travel for some reasons. Some enjoy the comfort of their homes. Others do not travel for fear of being robbed or losing their belongings.There are people who would rather put their money on material needs. Of course, journeys have some disadvantages, for example 1. high costs of traveling, 2. danger of disease, etc. So all you need to do is to take extra precautions to be sure that you have a safe journey. I am sure that pleasure of traveling and getting new experience is more important. Especially for those who enjoy the comfort of their homes there is one good saying â€Å"No one realizes how beautiful it is to travel until he comes home and rests his head on his old, familiar pillow†. To sum up, 1. traveling is a very good way of spending time. . It can educate, give impressions, nice memories and let make friends. I can advise people to travel as â€Å"The world is a book and those who do not travel read only one page . † I’m fond of traveling and would travel much if I had a chance ? I think many people have travelled at least once at their life. I live fourteen years only but I have already travelled a lot. I love travelling very much. However, there are some advantages and disadvantages of travelling. 1. On the one hand, it is very interesting to learn more about other countries and about the world in a whole. 2. ou can meet new people and friends. Furthermore, if you travel abroad, you can practice a foreign language, for example, English. On the other hand, there are some drawbacks with travelling. 1. It is not so comfortable to travel to other countries, especially if it is far from your home. You must take a big luggage with you and it is very heavy. 2. Moreover, it is easier to learn interesting facts about exciting places from books and TV programmes and it very convenient in any case, isn’t it? 3. The third fact is that you just cannot leave your home animals without any look and care. here are many ways of spending our time. One of them is travelling. It has its own advantages and disadvantages. 1. First advantage of travelling is visiting interesting places and meeting new people. 2. It is connected with getting to know other cultures and traditions which is surely valuable. If you live in Russia, you can not leave the country, and lodge in its distant area and open for yourself something absolutely new. 3. Secondly, it is usually said that journeys educate, so whilst travelling as well as exploration we can make our knowledge wider. . Also we become more experienced and ready to cope with surrounding world if we learn something while being in journey. 5. The trip to other country is possibility to practise a foreign language, to improve the pronunciation, to learn about dialects. Such experience can help with study and in a crisis situation. Of couse, journeys has some crucial disadvantages. 1. Firstly, costs of travelling are often quiet hi gh for example travelling by plane, so naturally not everyone can afford. Therefore not all is presumed to themselves by trips abroad. . What is more, journeys especially foreign ones expose us to danger of disease or even death. Travelling can lead to fall ill and maybe then to expensive treatment or in case of fatal accident like for instance car and aerial one to death of many people. 3. Now many people refuse trips abroad, being afraid to catch one of flu kinds. A flu chandes every year, but cases of diseases and lethal outcomes recently have become frequent. 4. The next disadvantage is fatigue that occur while travelling.Most journeys last very long and it can make us feel tired. To sum up, travelling is a very good way of spending time. It can educate, give impressions, nice memories and let make friends. However, in my opinion travelling in spite of its whole advantages, it should not be the only way to learn about the world and ourselves. ? 5. Disadvantages: Unfamiliar terri tory may cause discomfort, travel expenses, being away from home/family, not being able to commuinicate well with the natives, getting travel sick and being unable to enjoy the experience.
