Assignment Example The living things respond to the environment mainly through the receptors that responds to stimuli; a stimulus is a kind of energy such as chemical energy and sunlight energy. When a substance is highly concentrated outside the cell than the concentration inside the cell, diffusion or osmosis takes place thus enabling them to multiply (Deising, 23). From the above description, it is clear that CukE and Milk enabled the cells in the culture dish to multiply since the reindeer cells were activated. To illustrate this further a given fluid that can either be containing high concentration of salt or sugar outside a cell is likely to enter the cell if the cell is lowly concentrated. A given change in the blood sugar level is described as a deviation from homeostasis that the body works in order to reverse. Due to the fact that different receptors respond to different stimuli thus causing changes in the cell, the reindeer cells were therefore stimulated by the milk to multiply. ... ion of ciliate protozoa in the year 1895 as he made a comparison between the reindeer that originated from domestic ruminant and the reindeer from the zoological garden in Germany. He concluded that both were the same, Lubinski who worked in Northern Canada with the caribou (Starr, 87) further proved these results in 1958. The UV rays originating from the sun usually have an effect on the reindeer cells in one way or another as it is described in the book of Acts Climate Impact Assessment – Scientific report`. This is well illustrated as follows; various studies have shown that the exposure of enhanced UV radiation interferes with the growth of cells whereby the larger cells are inhibited to a larger extent as compared to the smaller ones (Karentz et al). Other scientists such as Vincent and Laurion further made an evaluation in 1998 that the smaller cells resisted the UV rays on a great deal as compared to the large cells. The UV rays inhibit photosynthesis from taking place within the cell because it interferes with the whole process (Starr, 426). Therefore, the UV rays have the ability to destroy the reindeer cells thus reducing their number. The UV rays in connection to the DNA Damage Checkpoint Genes might have also played a big role in this context by lowering down the number of cells. With reference to the book of checkpoint Controls and Cancer`, it is described as a signal cascade that plays a big role in blocking the cell cycle at the metaphase, G1, G2 and in slowing down the DNA replication rate in phase S. Apart from the cell cycle blockage, the cells also respond in many different ways such as DNA repair, apoptosis and in the activation of the transcription. However, many genes have damaged the DNA checkpoint pathways (Holzapfel &Naughton, 125). As soon

Famous Thinkers Essay Example for Free

Famous Thinkers Essay There are many famous thinkers that have lived on this earth who have made significant changes to everyones lives. A couple famous thinkers stand out amongst them all. These two are Mr. Bill Gates and Reverend Dr. Martin Luther King, Jr. Their contributions society have been great and were based off of their personal, social and political environments. They had both sought to solve problems or issues that people faced and they were able to provide solutions and implement them. The solutions they provided all followed a creative process, which will be compared to each other, and their ideas will be critiqued to discuss what they could have done differently. Contributions to Society Mr. Bill Gates and Reverend Dr. Martin Luther King Jr. have both contributed to society in different ways. Bill Gates had gained immense wealth through the creation and sales of Microsoft Windows, and he is using this wealth for philanthropic reasons. The Bill and Melinda Gates Foundation contributes to societies throughout the world. Their contributions range from providing vaccines in Africa, to financial services for the poor in the United States. These contributions affect society as they provide better health by helping prevent illness and helping better the lives of those less fortunate. Reverend Dr. Martin Luther King Jr. lead the change in gaining equal civil rights for African Americans by using nonviolent civil disobedience. The Environment Mr Bill Gates and Reverend Dr. Martin Luther King Jr. lived in different environments which attributed to their creativity in solving problems or issues. Bill Gates was raised in a financially responsible family, and attended a preparatory school which allowed him to focus on computer programming. This environment allowed Bill Gates to excel in what he loved and create the Microsoft organization. Bill Gates gained enormous wealth through his creation of Microsoft, which he now uses for the Bill and Melinda Gates Foundation. Reverend Dr. Martin Luther King Jr. lived in a rough environment. He grew up where African Americans where considered a lesser person and were segregated because of their race. This eventually lead Martin Luther King Jr. to take lead in the civil rights movement, which brought him to direct the march on Washington, D.C and give his I Have a Dream speech. Solving Problems or Issues Mr. Bill Gates and Reverend Dr. Martin Luther King Jr. both address issues in society. Bill Gates addresses issues across the world, where Martin Luther King Jr. addresses civil rights issues in the United States. Bill Gates, through the Bill and Melinda Gates Foundation, currently aids in numerous issues throughout the world. Some of the more widely known issues are support for better education in the United States, and contributions to providing vaccinations in Africa. The issues that Bill Gates seeks to solve is poor education in the United States and to prevent disease and death in developing countries. Martin Luther King Jr. had addressed the civil rights issues to help gain equal rights for African Americans in the United States by use of nonviolent civil disobedience. Solutions The Bill and Melinda Gates foundation works through funding other non-profit organizations working towards the common goal of helping impoverished people, providing health services in developing countries, and helping better the education system in the United States. Reverend Dr. Martin Luther King Jr. had a solution to bring the people together and spread the word of equal civil rights through speech, and motivation. Martin Luther King Jr. spoke at several different venues through the United States prior to the I Have a Dream speech in Washington, D.C. At the I Have a Dream speech, over 250,000 people attended and marched, showing non-violent civil disobedience. (The Nobel Foundation, 1964). Comparing the Creative Processes Bill Gates creative process was very simple in the fact that he has money, and wants to do good with it. His process was to create the Bill and Melinda Gates Foundation, find non-profit organizations that share a common goal, support them financially and repeat the process. Reverend Dr. Martin Luther King Jr. had a more complex creative process, where he had to bring the African American people together and get the leaders of the United States to listen. Martin Luther King Jr. began by traveling the United States, speaking where civil rights of African Americans where being denied. Through his speeches and travel, he brought together the African American people and accomplished the goal of gaining equal civil rights (The Nobel Foundation, 1964). Critique of Ideas The Bill and Melinda Gates Foundation can take an active role in their philanthropic ideals. The foundation currently supports other non-profit organizations that work toward the foundations goals. If Bill Gates could turn the foundation around and actively work towards their goals by doing something themselves, they may achieve greater success as other organization seeking support can follow their lead. Reverend Dr. Martin Luther King Jr. should not have done anything different. His motives of showing the world that the African American people are humans too, and deserve equal civil rights was conducted in a non-violent manner and accomplished his goal to gain equal civil rights. Conclusion Mr. Bill Gates and Reverend Dr. Martin Luther King, Jr. have provided great contributions to society across the world and in the United States. Their environments helped bring about this desire to contribute as they had both sought to solve problems or issues faced by society. The solutions they provided all followed a creative process, which Bill Gates could have done a better job at and Martin Luther King Jr. couldnt have done better.

Free Hamlet Essays: Use of Deception in Hamlet :: GCSE English Literature Coursework

Use of Deception in Hamlet Hamlet is a play by William Shakespeare about a prince named Hamlet who was spoken to by the ghost of his dead father telling Hamlet to kill his uncle Claudius (the new king) because Claudius killed him. The story revolves around Hamlet's dillema of how to kill his uncle while being deceptive enough so that no one finds out about the ghost. This essay will prove how deception is often used in Hamlet for many reasons. Claudius uses deception to protect himself from being prosecuted for his crime of killing the King. No one knows what the deal is with Gertrude because she deceives everybody by keeping to herself all the time keeping everyone from knowing anything. By using quotes from the book I will prove how these two (Claudius and Gertrude) and among a few others , use deception for different reasons and in different ways. A lot of the times it is to protect someone, or themselvs because they believe that the truth will hurt more than their lies. Claudius decieves everyone in different ways and at different times , always and only to protect himself from everyone else finding out that he killed the king. We can't truly say that he deceived Gertrude or not because we still don't know if she knows about Claudius killing the king or not because that is part of her own deception , but we know that he deceived the people and Hamlet himself (before he talks to the ghost). This next quote comes from the ghost of the king convicting Claudius of the murder ,"If thou didst ever thy dear father love- revenge his foul and most unnatural murder(p.57, act1,scene5 ,lines29-31). This quote proves that Claudius actually did commit the murder. This next quote is from Claudius himself after the funeral and the wedding giving a speach about the death of the king and the whole deal with Fortinbras,"To our most valiant brother-so much for him(p.21, act1 ,scene2 ,line25)." This quote shows that Claudius obviously doesn't have much remorse for his d ead brother and might be covering up the fact that he killed him. And we all know what that means...What does it mean?! It means that he actually is the rat and is the evil one in the play. Hamlet's deception , possibly the cruelest of all. Maybe even though Hamlet's deception was derived from Claudius's deception , it is the one that killed everybody.

Elite Essay

It is now that our political leaders and decisions have made up for what they were accounted for and have provided the back-bone of America today. Our government is what establishes America's decisions. Although some consequences can be made from what their previous aspects were, and how some of the decisions have made distrust in the government from Americans, it is only with said that, â€Å"Their failure to act, their failure to make decisions, is itself an act that is often of greater consent ounces than the decisions they do make. It's not necessarily the cause and effect of their decisions, but the act f speaking for America and doing something about the complications that arises within our world and our country to do the best they can to provide security and freedom even though there are limitations to freedom for security. Mills has stated, â€Å"The assumption that the security of the nation supposedly rests upon great secrecy of plan and intent. Along with the statement, â€Å"With the wide secrecy covering their operations and decisions, the power elite can mask their intentions, operations, and further consolidation. † I believe Mills is pointing out the directive of our national security being in the hands of the political officials because the government is the elite officials of America and has the authority to reach beyond the limits of other powers. Some may say the military is the elite of America because of the power and figure they portray.One may believe that the military is the most elite because they have more representatives, leaders and followers than those of our political leaders. One may obtain the fact that the military protects and has the secrecy of the united States in withstanding war power, but this is not accurate concerning the fact that the government has authority over the litany's actions. Mills has stated, â€Å"The military order, once a slim establishment in a context of distrust fed by State militia, has beco me the largest and most expensive feature of government.. Thus proving my element for elite power containing that the military is not established without the governments control and authority to make decisions for the military. One may believe that corporate has the most elite power over all, but corporations only have financial power not power over the decisions that are made within our country financially. Our political establishments indeed are ended by corporate, but they cannot make the decisions nor have the authority to do what the government can.The government tells corporate where to spend their money and what they can spend it on. â€Å"The decisions of a handful of corporations bear upon military and political as well as upon economic developments around the world. † Mills has stated which is proof along with my statement on economic decisions going through the government before corporate is able to take action on what they are deciding to do. In conclusion politic al officials are the most elite of the United States today.My opinion is not disregarding the other elite powers Mills has claimed above, but only withstanding that political power is the most elite out of the two other objectives. Nothing can go forward without the government's approval and action to speak for Our country. Military is just a figure of power for the people to obtain a sense of hope and security for our country along with corporate financial aid to help establish what needs to be conquered within our society and to help what decisions the government makes. â€Å"Everyone knows somebody has got to run the show, and that somebody usually does. † (C. Wright Mills)

Environmental Analysis Essay

Landfill gas is generated during the decomposition of organic substances in municipal and industrial wastes. Since it is made up of powerful greenhouse gases, primarily methane gas and carbon dioxide, the prevention of escape to atmosphere is desirable and has the added benefit of being utilised as a renewable energy source (Clarke Energy, 2014). One such company focussed on dealing with this issue is Landfill Gas Industries Pty Ltd (L.G.I. Pty Ltd) they are ‘a specialist designer, supplier, installer, and operator of systems that capture, extract and burn gas produced in landfills’ (L.G.I. Pty Ltd, 2014). L.G.I. Pty Ltd has several opportunities that could impact the company’s operations in Australia, such as government regulation, the number of councils and landfills available and the fact that all landfills require a solution to the landfill gas problem. However L.G.I. Pty Ltd also has several threats potentially impacting its operations, for example from large energy generators, large waste companies and opposition to landfill gas. With the continuing pace of global environmental awareness and a general growing consensus about the potential damage of greenhouse gases, the Australian Government may introduction legislation and associated taxation such as the use of carbon credits that are designed punish landfill owners with unabated gas emissions (Department of the Environment, 2011). A company such as L.G.I. Pty Ltd is well placed to install systems that can reduce these emissions and in turn reduce the financial penalties of operating a landfill, many of which are run by local councils and therefore paid for directly by ratepayers. With 565 local government councils in Australia (The Department of Infrastructure and Regional Development, 2014) and each with a need to process its residents’ garbage, many of which themselves operate landfill sites and/or have legacy landfills within their boundaries. Whilst the market has a finite limit there is considerable appeal for councils to adapt such technologies at their landfills and has the potential to generate ‘huge savings for [councils] and the environment’ (Landfill Gas Pty Ltd, 2008). L.G.I. Pty Ltd is committed to take advantage of councils’ needs by having ‘developed successful landfill gas installations on sites of all scales across Australia’ (Landfill Gas Industries Pty Ltd, 2014). Wherever there is a landfill, there is potential dangers aside from the environmental concerns unless mitigation techniques are employed, such as the risk of fire and explosion which for example  occurred in Loscoe, England in 1986 when a nearby house was destroyed (Danish EPA, 2001). There is also the potential of gas migration to occur below the surface and in turn contaminate the groundwater (Environment Protection Authority, 2008). If a landfill site is not suitable for electricity production, gas mitigation is nonetheless desired for safety and hygiene reasons. L.G.I. Pty Ltd ‘manufactures and installs its own range of state of the art flares’ (Landfill Gas Industries Pty Ltd, 2014) allowing the flammable gases to be safely burnt off. Therefore all current and legacy landfill sites are potential business for L.G.I. Pty Ltd The first major threat to L.G.I. Pty Ltd comes from existing large energy generators, such as AGL, Origin and Energy Australia, these 3 companies have a combined market share of over 60% of the energy sector (IBISWorld, 2014). As these companies have the need to supply electricity to their customers they have the desire to source viable and sustainable generation methods, AGL for example already ‘owns and operates several renewable landfill gas and biogas (sewage) generation facilities across Australia’ (AGL, 2014). If these companies decide to expand in this sector and compete for this resource, they could undermine L.G.I. Pty Ltd’s potential simply by means of more efficient access to financial capital required to setup and by the greater potential political bargaining power they possess such as when competing for tenders. Such as with large energy generators, large waste companies also pose a potential threat for L.G.I. Pty Ltd. Many councils utilise outsourced waste collection, processing, recycling and landfill operators to fulfil their needs. Operators such as Veolia and Sita which operate landfills as part of their business must ‘manage odour across [their] landfills in accordance with the Environmental Protection Licence’ (Sita, 2014). These operators have their own equipment and methods for gas mitigation and therefore pose a threat to L.G.I. Pty Ltd if more councils outsource their waste needs to private companies, they in turn aside from environmental requirements have a commercial obligation to seek profit. There is nonetheless opposition to companies that seek to turn landfill gas into electricity, for several reasons such as its relative high costs, local air pollution but namely it suggests that it is acceptable to dump waste at landfill sites rather than pursue waste minimisa tion or recycling initiatives (Shrank, 2011). Veolia states that it ‘encourages waste  minimisation and recycling’ (Veolia, 2014), however if a financial incentive exists if it fails that endeavour then people are right to be sceptical. The threat of a change in public opinion and awareness towards waste disposal could potentially impact L.G.I. Pty Ltd, particularly if they are seen as not encouraging waste minimisation or if their operations produce an unacceptable amount of air pollution. Landfill gas is an unavoidable by-product of our modern society and it possess several risks if left unmanaged to public health and safety. L.G.I. Pty Ltd is well placed to mitigate these risks and also potentially return a financial benefit to its clients, specifically local councils. In terms of opportunities, L.G.I. Pty Ltd faces a finite barrier in terms of number of landfills in Australia, it may seek to export its expertise to markets overseas to pursue further growth. It may also be of benefit to lobby government to encourage further legislation and taxation penalties regarding greenhouse gas emissions, potentially expanding its market. Of the threats facing L.G.I. Pty Ltd, the biggest is represented by existing the large companies in the electricity generating and waste disposal sectors, who invariable have better access to capital and lobbying power to further develop this industry. Finally, public opinion could negatively impact L.G.I. Pty Ltd if they are seen to be exploiting a resource which ideally should be minimised in the first instance. Clarke Energy, (2014).

(Wikipedia) A year later, Flora married a widower, John London and Jack adopts his surname â€Å"London†. At the age of two, the London family moved to Oakland after their son suffered a near fatal case of diphtheria and continued to live within the city though they moved to different locations. During this time he attends West End Elementary in 1882 and then enrolls in Cole Grammar School in 1887 and two years later (at the age of 15), he graduates as an 8th grader.

Free Essays on Jack London The story of â€Å"To build a Fire† by Jack London is about one mans lack of ability to survive under extremely harsh conditions. I found this story to be unappealing and a very boring read. I felt that Jack London wrote it more like an instruction manual of survival than a story, as he repeatedly attempts to teach the reader survival techniques such as building fires, avoiding dangerous springs, and navigating a creek. This idea is especially prevalent in the latter part of the story, when the main character continuously refers to what the old-timer on Sulphur Creek had told him about travel in the Yukon, especially alone. As his situation proceeds to grow worse, the narrator thinks more and more about survival ideas that he had learned or that the old-timer had told him. The story even goes as far as killing animals and using their fur as warmth in order to thaw out from the frostbite. This idea is also evident with Jack London’s character development or the narrator. He purposely created him simplistic and this enabled Mr. London to talk about survival. This concept holds true all the way to the point that we, the readers, do not even learn the narrators or the dogs name. London also tells the readers that his character â€Å"was without imagination† and â€Å"he was quick and alert in the things of life, but only in the things, and not in the significances.† By not being held down by character development and deep thought by the character, London is able to constantly discuss the what to do and what not to do while in a severe environment. While you can argue this was a story of a naà ¯ve man traveling foolishly through the Yukon, one that attempts to take on nature and loses badly. Yes, this story does involve the aspect of the ignorance of man and their arrogance toward nature and peoples advice. This is portrayed by the narrator through thoughts like, â€Å"any man who was a man could travel alone.† This point is also reaffirme...

Life Cycle of The Queen Bumblebee

Life Cycle of The Queen Bumblebee There are more than 255 species of bumblebees worldwide. All share similar physical features: they are round and fuzzy insects with short wings which flap back and forth rather than up and down. Unlike honey bees, bumblebees are not aggressive, are unlikely to sting, and produce relatively little honey. Bumblebees are, however, major pollinators. Beating their wings as fast as 130 times per second, their large bodies vibrate very quickly. This movement releases pollen, helping crops to grow.  Ã‚   The health and well-being of a bumblebee colony depend very largely on the queen bee. The queen, alone, is responsible for bumblebee reproduction; the other bees in the colony spend the majority of their time caring for the queen and her offspring. Unlike honey bees, which overwinter as a colony by clustering together, bumblebees (Genus Bombus) live from spring to fall. Only the fertilized bumblebee queen will survive the winter by finding shelter from the freezing temperatures. She spends the long, cold winter hidden away alone.   The Queen Bumblebee Emerges In spring, the queen emerges and searches for a suitable nest site, typically in an abandoned rodent nest or small cavity. In this space, she builds a ball of moss, hair, or grass, with a single entrance. Once the queen has constructed a suitable home, she prepares for her offspring. Preparing for Bumblebee Offspring The spring queen builds a wax honey pot and provisions it with nectar and pollen. Next, she collects pollen and forms it into a mound on the floor of her nest. She then lays eggs in the pollen and coats it with wax secreted from her body. Like a mother bird, the Bombus queen uses the warmth of her body to incubate her eggs. She sits on the pollen mound and raises her body temperature to between 98 ° and 102 ° Fahrenheit. For nourishment, she consumes honey from her wax pot, which is positioned within her reach. In four days, the eggs hatch. The Queen Bee Becomes a Mother The bumblebee queen continues her maternal care, foraging for pollen and feeding her offspring until they pupate. Only when this first brood emerges as bumblebee adults can she quit the daily tasks of foraging and housekeeping. For the remainder of the year, the queen concentrates her efforts on laying eggs. Workers help incubate her eggs, and the colony swells in number. At the end of summer, she begins laying some unfertilized eggs, which become males. The bumblebee queen allows some of her female offspring to become new, fertile queens. The Bumblebee Circle of Life With new queens ready to continue the genetic line, the bumblebee queen dies, her work complete. As winter approaches, the new queens and males mate. The males die soon after mating. The new generations of bumblebee queens seek shelter for the winter and wait until the following spring to begin new colonies. Many species of bumblebees are now endangered. There are many possible reasons for this, ranging from pollution and habitat loss to climate change.
