Differences between Prokaryotic and Eukaryotic, Plant and Animal Cells, Mechanism of Cellular Processes Free Essay Example, 2500 words

A knowledge of the different cell processes helps one understand the working of a cell at the better level. The process of binary fission was understood based on which population growth of bacterium was studied and doubling time was calculated. The difference between mitosis, meiosis and binary fission was understood as well. The main difference between photosynthesis and cellular respiration was seen and their roles were studied individually. Thus, the assignment gave a thorough insight into the working of different kinds of cells. Virtual Lab: Genetics Purpose: The aim of the work is to understand the basics of genetics and understand Mendel s laws of inheritance. Lab Observations: The virtual lab of drosophila established the laws of genetics where flies were selected according to their phenotypic characters and mated to obtain F1 and F2 generations. The Punnett square helped to understand the percentage of offsprings that could have a particular wing trait. Each result of the experiment complied with the ratios established by Mendel. In the first generation we obtained all Wild types thereby understanding that the wildl type gene was dominant over the recessive vestigial wing.

How Is Mass Media Effecting This Generations Sexuality

Television is one of most pervasive and influential forms of media. Sadly, there is a lot of sexual context on television. It is in movies, TV shows, and commercials. Sometimes it is subliminal but it can be obvious. I can admit to it myself I was completely ignorant to the sexual content in television shows I watched as a child, like show in Figure 1 now that I am older, I can clearly see the signs. Besides being naturally curious, TV is usual the first exposure to sexual content. Research show that sexual content is being shown early through television and that children 6 to 11 are attached to shows with high sexual content (Teenage Sexuality 39). (Figure 1 As a child, I did not notice the sex reference to pornographic magazines in the show Ed, Edd, and Eddy, 2003.) Not only is TV causing adolescents to become more curious but it is also influencing ideas about what is normal and expected during sexual activity (Kittleson 74). Because the way sex is present on TV, adolescents depict it as an activity without risks or consequences. Adolescents become oblivious to unplanned pregnancy, sexually transmitted diseases, and even sex addiction. It was until recent years that TV networks like MTV start airing reality shows about teenage girls becoming young parents. Shows such as Teen Mom and 16 Pregnant have a reverse effect on society because the teenage mothers of these shows are becoming celebrities off their pregnancies. This effect can leave adolescents confused about

No Impact Man free essay sample

People must use less energy, conserve nonrenewable resources, and minimize their negative impact on Earth. An example of this new way of living is that of Colin Beavan in his book, â€Å"No Impact Man. † It is a true story about the year he spent having no impact on the earth and living an entirely eco-effective life. Along with his family, he does so by minimizing his use of electricity, generating no waste, and watching every move they make to ensure his family makes no impact on Earth. Beavan is initially motivated by the global, highly publicized problems, his relationship with his family, and the guilt he feels for his lack of environmental action. Throughout the project, these motivations evolve and he is ultimately motivated by more personal, community problems, maintaining his new relationship with his family, and the guilt he feels about leaving the project. At first, Beavan is concerned with the largely publicized environmental problems. Select the most important and interesting motivating factors and explore how they directly led to the means and methods of such a drastic experiment. For example, why did Beavan shut the lights off when he could have spent a year lobbying his member of congress? Why did he give up some conveniences and products and not others? His motivations dictated his means. And why, for example, did he push through, even when he struggled with his own self-imposed rules and/or the difficulties that he faced in his environment? Finally, ask yourself how Beavan felt about continuing his project during the first week vs. during the last week. In your body paragraphs, find examples from the book and analyze how Beavan’s choices and writing prove your thesis. Do not simply summarize. Demonstrate how he successfully tackles these motivating factors and makes personal inroads at the same time as informing and inspiring his audience. Organize your paper by subtopics instead of moving linearly through the book as this often leads to summary (i. e. First Beavan did this, then he did this, etc. ). For instance, you could use motivating factors as subtopics and discuss how each factor evolves before moving on to the next. Audience Assume that your audience is college-educated (or is a fellow college student) who has read No Impact Man. You should avoid summarizing in this essay, and instead focus on providing evidence for analysis. Procedure Your analysis should include the following: 1. An introduction that introduces the topic of sustainable living, the title of the book, the author’s name, the author’s main goals and arguments, and a strong thesis statement. 2. Several body paragraphs that support your central assertion. Each of these paragraphs should be well-developed, coherent, and focused on a clear topic sentence. Incorporate 3-4 short quotations from the book to support your ideas. Otherwise, use paraphrase when providing evidence. You must also use at least one specific reference to a piece of evidence from the NIM documentary. The body paragraphs need transitions, topic sentences, and support. 3. A conclusion that communicates your thesis in a new way and emphasizes the importance of your topic to the reader. Use a quote from the text, or leave the reader a question to think about. . An MLA-formatted works cited page, including citations for both the book as well as the documentary. Formatting 3. 5-4. 5 pages. The essay must be typed (double-spaced) on 8. 5 x 11 inch sheets of white paper in standard font (for example, un-italicized, un-bolded, black, 12-point Times New Roman). Leave one inch of margin around the page. Left justify. Include your name, the instructor’s name, the title o f the course, and the date in the upper-left corner of the first page of each essay, but do not use a folder or cover sheet. Due Dates

The Ability to Empathize in Between the World and Me, a Book by Ta

The Ability to Empathize in Between the World and Me, a Book by Ta-Nehisis Coates Essay A large part of reading and experiencing Between the World and Me by Ta-Nehisi Coates revolves around the ability to empathize with Coates. Coates’s purpose behind writing this book lies in the recent surge of police brutality on black people, such as with the murders of Trayvon Martin and Michael Brown. This motivation of Coates’s is furthered by his position as a father, which manifests itself as the book taking form as a letter to his teenage son. Throughout the book, Coates uses stories, both personal and impersonal, to get the reader to see the world through his own eyes, and educate the reader about what it means to be black in America in a push to change the state of the present. Coates spends a great deal of time writing about his time at Howard University, his childhood, his son, and his views on recent murders in order to achieve this goal. In â€Å"Empathy is a Privilege?† by John Paul Rollert in The Atlantic Monthly, Rollert writes that the â€Å"sustained terror† described by Coates through his accounts of crimes on black people â€Å"prevents the imaginative escape of empathy by making the flesh unforgettable.† This idea of making flesh unforgettable is used by Coates with his strategy of forcing the reader to come face-to-face with a very bleak and sad reality of unjustified murders portrayed in a haunting way not commonly seen on television or in newspapers. This technique used by Coates makes the reader struggle with not empathizing on at least some sort of level. Ultimately, Coates’s rhetoric of detailed stories, and the way he paints those in the stories as individuals, rather than headlines, makes his argument more effective, because he sets up the reader to empathize with not only him, but also those involved in his stories, such as Prince Jones or his own son. In a description of Prince Jones, Coates wrote â€Å"His face was lean, brown, and beautiful, and across that face, I saw the open, easy smile of Prince Carmen Jones† (77). If Coates had left out such touching and visceral accounts of many events, Coates’s purpose of education would fall deaf on many ears, especially white readers. However, something Coates either fails to realizes or chooses to ignore is the fact that empathy needs to flows both ways in his writing. Coates’s inability to detach from his own self and step away from his, although justified, anger potentially hurts his credibility. The amount of anger in his rhetoric and lack of personal empathizing may deter some readers from wanting to keep an open mind or adopt Coates’s perspective. When writing the difference between black and white children, Coates stated â€Å"No one told those little white children, with their tricycles, to be twice as good. I imagined their parents telling them to take twice as much† (91). Coates’s hostility towards children and his assumptions of how white parents raise their children can easily create offense, because of how serious parenthood is to most parents. Coates has a tendency to make generalizations about white people as a whole, all while asking for white people to stop making gener alizations about black people as a whole. This sort of double standard can set Coates’s rhetorical situation up for failure, because it gives Coates’s reputation room to seem invalid and his argument overly biased. When speaking about President Obama, Rollert mentions Obama’s writing in The Audacity of Hope, specifically, â€Å"to think clearly about race, then, requires us to see the world on a split screen †¦ to acknowledge the sins of the past and the challenges of the present without becoming trapped in cynicism or despair.’† Coates’s â€Å"trauma of fearfulness† hurts his ability to maintain a non-cynical perspective, and this is evident in his account of the events on 9/11 by saying â€Å"my heart was cold. I had disasters all my own.† Also, his slander of â€Å"the ridiculous pageantry of flags, the machismo of firemen, the overwrought slogan. Damn it all.† Although Coates may have every right to be angry, his anger should not mean trivializing such a large event in American history that so many people feel strongly about. His negativity towards 9/11, along with how often he criticizes the merits of the American Dream, may hinder the ability of some readers to empathize with Coates, because they themselves may begin to feel attacked. Coates’s whole purpose relies heavily on his readers’ ability to empathize. Coates wants all of his readers to empathize with him, because it is his best chance of convincing his readers of his argument. When Coates begins to toe the line of what is and is not offensive, this hurts his chances of all of his readers empathizing with him. Athletes and Domestic Violence EssayAlthough Coates has some constraints working against him, such as the magnitude of his anger and how it warps his ability to appeal to some audiences at times, he does an amazing and effective job of persuading the reader and getting them to feel what he himself is feeling on a small scale. Coates’s choices in his diction, framing, and stories are very purposeful, because he understands what it takes to get people to care. And by doing it enough, Coates makes it near impossible for his reader to ignore his palpable fear, anger, and sadness over race relations in America. There is a great deal more to stories than just providing evidence. And there is a great deal more involved when reading and experiencing this book than simply gliding your eyes across the pages; the reader must step out from their own world and into Coates’s in order to fully grasp what Coates is trying to accomplish here.
