Polar Bears :: essays research papers fc

Polar Bear is the name for a white bear found on the icy sea of the Arctic throughout the North Polar basin. Being the only bear considered being marine, it is longer than other bears and streamlined for aquatic life. It has the â€Å"plantigrade† feet (heel and sole touching the ground) which are typical in all bears, with five sharp, claws on each foot for grasping at the ice and holding its prey. Long hair between the pads protects the bear's feet from the cold and provides traction on the ice so he doesn’t slip. Hard hairs on the forelegs, and very wide front feet, help the bear swim. All polar bears are white, although their fur may yellow in the summer because of the fat from animals it kills. The largest wild bears ever weighed—were more than 800 kg (which is more than 1800 lb)—have been polar bears. However, most male polar bears weigh an average of about 350 kg (about 880 lb), and most females weigh about 250 kg (550 lb). Polar bears have a strong navigational sense, an extremely good sense of smell, and they are extremely good at solving problems in order to obtain food. They eat primarily ringed seals, and sometimes they also enjoy bearded seals, walruses, or even white whales. They also feed on berries, sedges, mussels, and kelp when they have no other food sources left. As with other â€Å"true† bears, polar-bear mothers and young create strong bonds. The young cubs are very small when they are born: about 1 kg (about 2.2 lb). Their eyes remain closed for about 40 days and they must be fed every few hours. The mother keeps them close to make sure that they stay warm. Except during the breeding season, male polar bears are solitary and walk over vast amounts of sea ice while hunting. During the breeding season (which is from May to June), the males fight nonstop over females. Both the male and female may mate with other individuals as well.

Enzyme Reaction Rates Under Different Conditions

Enzyme Reaction Rates Under Different Conditions Introduction In this lab you will observe how the rate of a reaction is changed as certain factors are changed. You will observe how changing factors like temperature, pH, substrate concentration, and enzyme concentration changes the rate of an enzymatic reaction. In this experiment you will act as an enzyme by breaking toothpicks witch act as substrates. After observing the results of this experiment you will be able to determine what causes the fastest enzymatic reaction. Methods and MaterialsThe materials needed for this lab are 240 toothpicks and a timing mechanism. To start you should divide your toothpicks into six piles of forty toothpicks. Then you should break as many toothpicks as you can in different time intervals. You should note the amount of toothpicks broken at: 0,10,30,60,120, and 180 seconds. Then you should repeat this process with other factors added in. (In the lab make up we just did a control table) Results For o ur results we took class averages of the various experiments. The class averages are shown in the graph.Graph 1. Class Average Breakdown Discussion/ Conclusion After performing our tests we came to the following conclusions. Increase in enzyme concentration speeds up the enzymatic rate. The reason for this is when you increase the amount of enzymes (enzyme concentration) then you have more enzymes breaking substrates. Since there are more enzymes more substrates will be broken down than if you have less enzymes. Decrease of temperature leads to decrease of enzymatic rate. This is because when you decrease temperature, you decrease energy.Since energy is decreased the speed of the enzymatic rate goes down. Decrease in substrate concentration leads to decrease in enzymatic rate. When the number of substrates goes down the enzymatic rate goes down because since there is less substrate to break down. The farther the pH is from 7 the slower the enzymatic rate is. This is because ionic bo nds (how substrate and enzyme bonds) work better when pH is 7. Through the test preformed I have learned what factors contribute to the enzymatic rate and how they contribute to the enzymatic rate.

Robert Boyle essays

Robert Boyle essays Robert Boyle was born in Ireland in the county of Waterford in the city of Lismore on the 25th of January 1627. His father Richard Boyle, Earl of Cork, had left England in 1588. Roberts mother, Catherine Fenton Boyle, was Richards second wife. Robert was the seventh son. His parents had a total of fifteen children. At the age of twelve Roberts father sent him on a tour of Europe eventually leading him to Geneva. There he began to study, with a private tutor, mathematics and ... he grew very well acquainted with the most useful part of arithmetic, geometry, with its subordinates, the doctrine of the sphere, that of the globe, and fortification. There had been a civil war going on in England at the time. When the war had finished Cromwell granted Irish lands to the English colonists. As a result of this, Richard became a very rich man. He then no longer had a need for a source of income and was able to devote both himself and his time to science. He contributed to physics and chemistry. His biggest contribution being Boyles Law, which relates volume and pressure in a gas. The law describes an ideal gas. This law can be found in the appendix written to Boyles work New Experiments Physio Mechanical, Touching the Springs of the Air and its Effects. Using a vacuum he discovered that sound did not travel in a vacuum, he proved that fire required air to burn, and he tested airs elastic properties. Robert published his findings through the Royal Society, of which he was a founding fellow. He aimed towards establishing chemistry as a mathematical science. He argued a mechanistic theory of matter. Its complex look is actually just simple mathematical laws applied to simple fundamental particles. In 1670, Boyle had a stroke. He slowly regained his health and continued to conduct research and experiment. In 1680 he declined the title of Pre ...

Presentation of teen culture as portrayed in the film A Rebel without a Cause

Presentation of teen culture as portrayed in the film A Rebel without a Cause â€Å"A rebel without a cause† is a film whose theme is based on the American youth who are misunderstood, restless and belong to the middle-class society. The film is based on a book written earlier by Dr Robert Lindners 1944, a factual book titled; â€Å"Rebel without a Cause,† which tells the story of a criminal psychopath in the years after the second world war.

The story symbolizes the rebellious and idealistic protagonist search for a cause, which is honesty and decency in a hypoctrical world. Due to its theme no one would have been better fit for the main a ctor’s position like James Dean did shortly before his death which occurred a month before the feature opened at the Astor Theatre (Lindners, p.89). The film is divided into five main acts: conflict between parents and children leading to lack of a father factor, interaction between teenagers, and climatic challenge of the dare devil, peaceful and loving denouement and lastly the final tragedy of the three young people. The three main characters Jim, Judy and Plato represent the teenagers of the 1950’s .The film brings out their teen culture which is not so different with the current modern culture. Jim, the main character, is presented as a rebellious character who is a loner and a troublemaker seen as a drunkard when the film starts. He appears dressed like an adult in dark suit and a tie. He is also seen holding a monkey hence, bringing out his own essential innocence, sensitivity, and immaturity. He is arrested for drunkenness and ends up in jail where he meets new friends. He is disappointed by his parents who are ever arguing and are blamed for his alienation. One of the teenagers he meets is Judy, a desperate girl in need of loving, she has problems with her father who she is convinced that he does not love her. She is all dressed up for him with red lipstick but her father disapproves her maturity and smears off the lipsticks from her lips. Judy is like many teenagers living in the current teen culture, who are caught in family love drama. The issue has been portrayed in a current film â€Å"never been kissed†.

Plato is the other teen character who is brought to the police station by a powerless nanny for shooting puppies. He is hurt and thinks no one can help him since his parents are always away from home and more so, it was his birthday and his parents were not present. The three attend the same school, Dawson’s high school, and on the first day Jim tries to create friendship with the next door neighbor, Judy but she ignores him. Their conversation has words of juvenile attitudes, peer pressure, attraction and repulsion. Jim: Hi. Hi. Wait a minute. (He runs down to her) Hi. I had seen you before.

Jim falls prey of them, they flatten his tyre so as to irritate him and get him to fight, but he walks away. They decide to call him a chicken and he gets irritated too much that he wanted to fight them but they told him that was an invitation to contest at the chicken dare. He decides to engage in the chicken game but first, he consults his father who tells him not to fight but Jim asks him; â€Å"What can you do when you have to be a man? He engages in the contest and wins but the group’s leader, Buzz, dies in the game (Lindners, p. 80). Plato looks at Jim as a potential hero figure and they later become friends in class but Plato is actually sexually interested in Jim, who is seen to understand the melancholy of ad olescence. Plato touches Jim on the shoulder suggestively after the chicken competition. Jim offers to give him a ride home, but in the car Plato asks Jim Hey, you want to come home with me? I mean, theres nobody home at my house, and heck, Im not tired. Are you? (Lindners, p.48). Jim is attracted to Judy, while Plato tries to discourage him because he feels Judy will threaten their relationship. The gang is annoyed with Jim because they think he rattled them to the police not because of Buzz’s death, but for stealing the cars. The three decide to hide from the gang in an abandoned house and started playing games. While the other teenagers are idling in a mansion, Plato is deserted and emotionally unbalanced, feeling betrayed by his parent. â€Å"He took a gun from his mother’s room and starts firing. He hides in the planetarium, and Jim enters to get him and tries to talk to him but he gets scared and runs away. The police see him with the gun and shoot him.† Jim is agonized by the meaningless murder and his failure to prevent it; he goes on knees and crawling close to his pal’s body crying loudly.† He finally becomes more adult like due to this experience. He accepts his both parents and his father promises to assume responsibility and face things like a man. In conclusion the film uses the three characters to portray teenagers’ behavior and lifestyle then, although not much has changed in today’s society since teenagers almost behave the same irrespective of the era since they are still faced by the same issues of relationships, family and school.Advertising Looking for essay on art and design?

A Critique Interpretation of the Behind the Beautiful Forevers

A Critique Interpretation of the Behind the Beautiful Forevers The Accident of Birth One’s birthplace can disproportionately influence one’s quality of life. Where per capita income is low and public education not as ubiquitous as in most of the first world, people often experience oppressive limits in terms of their economic opportunities. In India, the cultural remnants of their caste system as well as a general lack of social equality present nearly insurmountable barriers to those who are impoverished. Many Indian families, such as those seen in Behind the Beautiful Forevers, often spend generations with little to no improvement in their quality of life. The people that populate slums like Annawadi are usually victims of the accident of birth, meaning that they were born into poverty. However, although one’s birth determines their economic opportunity, it is worth noting that the accident of birth can have an aggregate effect when already resource-strained societies continue to increase population. In Behind the Beautiful Forevers, it is shown that everyone in Annawadi is aware of the three main ways to get out of poverty (Boo 62). One can find an entrepreneurial niche and thus generate income for oneself, thus elevating one’s standard of living (62). One can also try to fight back against the corrupt system that tries to keep the masses impoverished for their own benefit (62). However, many people look to education as a means of elevating themselves from poverty (62). Each of these methods presents its own advantages and disadvantages, and each method is often very difficult for various reasons. Finding an entrepreneurial niche is often cited as a method for getting out of poverty. For example, the Husains were able to use the skills that their family had accumulated over generations to have better-than-average success as scavengers for recyclable materials (62). However, without any kind of financial education, and without access to capital, it is often insurmountably difficult to realize any kind of entrepreneurial activity, in particular when the ultimate goal is to operate a business in these low-income regions. Additionally, because of the lack of financial expertise, many of these people may end up running nearly identical businesses and competing with each other often to a destructive degree. This is exemplified by the extraordinary number of scavengers living in Annawadi and other slums constantly fighting over dumpsters like street gangs. This is also a function of population, which brings up the aforementioned issue of high birth rates. Working with a corrupt system can often provide a framework for an eventual legitimate ascent into the middle or upper class. For an example, we can look at Asha, who is the unofficial slumlord of Annawadi (17). One of her main sources of income is securing loans for residents of Annawadi, supposedly to jump-start businesses (24). However, she takes money from the loans as commission (25). In this scenario, the theft might not be considered corruption if the circumstances were normal. However, the loans are meant for small businesses and given out based on how many jobs the new business will create (24). Because Asha’s only stake in the loan is the commission, she does not care whether the business will create jobs, or even if there is a business. This myopic self-interest is bad for the economy of Mumbai because the borrowed government funds may not be repaid, and thus government money will have been wasted. Asha is not only a de facto broker of government loans. She also provides residents with access to education or jobs, usually for a fee as well (21). With the money she had aggregated from these corrupt activities, Asha was able to send her daughter, Manju, to a reputable school so that she could be educated and lead a productive life. Through this investment in human capital, Asha will hopefully elevate her entire family’s standard of living. In keeping with the theme of birth rates, it is worth noting that Manju is an only child. Education and vocational training are perhaps the most common way for one to elevate one’s standard of living. In general, the people that are impoverished are low-skilled or semi-skilled laborers. The fact that they are not necessarily trained in anything unique or sophisticated is what prevents them from finding gainful employment. This diminished opportunity for employment is derived from having a lesser skillset than someone who is more educated. Since they are unable to seek gainful employment, they are often unable to send their children to the same schools that they themselves were unable to afford, and the cycle continues. One of the main problems in Annawadi is that there is very little public access to education. Additionally, the public schools that are available are generally of poor quality. For example, of the public schools that are available, only about 40% of the educators even have a college education themselves (63). Furthermore, the schools generally have access to minimal public funding. This can be attributed to the fact that these schools are often the result of corrupt attempts to maintain an image rather than any truly altruistic attempt to educate the people (63). In this society, the overarching corruption has subsumed the mission of education and investment in human capital. Adding to the issue, a society with a quickly increasing population will make it more difficult to benefit from the pedagogical institutions because of increased pressure on resources. Large class sizes are proven to reduce the overall quality of education, but this is particularly true in environments where resources are already strained. For instance, it is highly improbable that there are any textbooks or workbooks available to students in the public schools of Annawadi. Therefore, although there are schools available, they do not necessarily provide the benefits one might imagine. This indicates that increasing access to education is likely not the sole solution to poverty. In places like India that have a historical caste system with social effects that persist, often none of these aforementioned methods will improve one’s employment prospects. Their low caste may decrease access to education and employment to begin with. Additionally, attempts to include historically low-caste people into jobs and governments are often circumvented by corruption. For example, a man named Subhash Sawant, running for the role of Corporator, was not a member of a historically low-caste lineage (51). However, he was able to manufacture the paperwork that said so and he was able to enter and win the election (51). This instance of fraud entitled him to a position meant for historically oppressed Indians. High levels of corruption will prevent even the noblest attempts to include oppressed peoples in the governance and economic activity of a society from achieving any significant result. Those that are in positions of power, without just governance, will simply continue to manipulate the system to keep their power. This means that attempts by the government to create opportunities for the existing population without changing the overall system of government cannot be the sole solution to poverty. Because there is very little ability to educate one’s children and thereby improve the economic value of said child, it is very common for families to have multiple children, voluntarily or otherwise. This is because these children will each earn income in any way that they can. And, since the families have no substantial income, they end up spending little if anything on their children. Ergo, the marginal benefit of an additional child usually outweighs the marginal cost. Furthermore, high mortality rates make it difficult to know exactly how many children one will have even one year in the future, so families make it a practice to have many, which can be thought of as a sort of income insurance. A consequence of high reproduction is perpetually increased competition for resources. Things like water and food become increasingly difficult to access over time if the population continues to grow with no economic improvement. For example, in all of Annawadi there were six faucets that would run water for a total of only three hours per day (53). As competition for resources increases, so do malnourishment and dehydration. These conditions can lead to increased health problems, and often can lead to obvious deficiencies like stunting the growth of a child or teenager (35). People often turn to alternative means to satisfy hunger when food is not available, like smoking the remains of a cigarette, or other cheap ways to achieve a drug high that eases the pain of hunger (35, 43). Since so much time is spent in the pursuit of these resources, it is no wonder that they are unable to focus on things like education or entrepreneurship. The accident of birth is often thought of as the idea that one is born into poverty. However, the implications of many accidents of birth can be appreciated as an aggregate phenomenon as well. Often, people born in impoverished areas are in poverty because everyone else around them was born into poverty. High birth rates are common in underdeveloped regions of the world, often because the act of human reproduction is quite desirable, even under circumstances where the addition of children to a family is unfavorable, as in Abdul’s family in the book (2). This is largely because these families are not capable of investing in human capital through education or vocational training. Ergo, having a child adds to the income potential of a family. Once these new people are born, they have individual needs to which society must attend. Also, these new children often end up in socially destructive behavior cycles identical to those of their parents and relatives. This will increase stress on society’s resources. Ergo, the accident of birth must not only be thought of as an individual’s circumstances of poverty, but also as an aggregate phenomenon of exponential population increase in already adverse circumstances, exacerbating the existing social and economic problems. In conclusion, the place in which one is born can disproportionately influence one’s quality of life and economic opportunity. However, this is not solely a phenomenon related to the chances of an individual. The accident of birth is a situation in which high birth rates in underdeveloped areas of the world decrease opportunity for all by continuously putting stress on what little resources are available. This stress perpetually pushes the impoverished further below the poverty line. This issue will continue to be a problem for as long as people do not have access to reasonably priced methods of contraception in the developing world.

How to use social media to raise awareness and reduce the rate of car Research Proposal

How to use social media to raise awareness and reduce the rate of car accidents - Research Proposal Example In addition, new hypotheses may be generated using numerical data collected during a research. However, it is the qualitative analysis of data rather than numerical computation that actually gives meaning to any given research. This research proposal attempts to study research methodologies (qualitative and quantitative), their characteristics, importance, suitability of application and circumstances under which one method is more suitable than the other. Further, it investigates the importance of using mixed methods of research. It is divided into three sections. The first section tackles into detail qualitative research, quantitative research and mixed research methods. The second section studies into detail the process of undertaking a quantitative research study, taking into detail the steps involved. The third section attempts to apply the processes and concepts of quantitative research methods to conduct a research on How to use social media to raise awareness and reduce the rate of car accidents. This type of research is n normally used when a researcher aims at gaining a deeper understanding of a specific event rather than a superficial understanding/ knowledge of a large sample in a population. The main goal of qualitative research is to provide a concise outlook into the order, structure and the exact relationships between the research parameters. Rather than introduce manipulative variables that impose the researcher’s operational definitions on the research parameters, it allows the true meaning of the research emerge on its own from the research. This means it is more flexible and adaptable to most situations since data collection tools, methods and concepts are easily adjusted to meet the needs of the research at any stage. In order to bring the best results out of every research situation, qualitative
