...Lesson 3 essay questions Exam # 25085400 1. Directional and disruptive selection can be compared because they both favor extreme phenotypes, they adjust to their environments over time and they both cause a shift in the distribution curve. The contrast in directional selection is the distribution curve shifts one way and only focuses on one extreme phenotype. An example of directional selection would be the gradual increase in size of the modern horse. This change occurred due to the environment changing from forest conditions to grassland conditions. The contrast in disruptive selection is the distribution curve shifts both ways and focuses on two or more phenotypes versus intermediate phenotypes. An example of disruptive selection is the British snails. They live in low-vegetation areas and in forest areas. Thrushes feed on the the snails with dark shells and no bands in the vegetation areas and they feed on the snails with the light bands in the forest areas. Therefore, these snails had to adapt to their own environment. 2. Overuse and misuse of antibiotics can cause resistant bacteria to form through natural selection. When you introduce selective pressure (antibiotics) to a bacterial infection, some of the bacteria can acquire “free” DNA from its environment. Which can mimic the antibiotics genetic make up. This causes some bacteria to create a resistant gene that can be passed to the next generation. As a result the genetically resistant bacteria keeps increasing...

...1. Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Eutrophication is a naturally occurring, slow, and inevitable process. However, when it is accelerated by human activity and water pollution called cultural eutrophication, it can lead to the premature aging and death of a body of water. Cultural eutrophication occurs when humans speed up the aging process by allowing excessive amounts of nutrients in such forms as sewage, detergents, and fertilizers to enter the ecosystem. 2. Compare and contrast the traits and growth patterns of opportunistic versus equilibrium populations. Provide one example of each. Opportunistic species use the r-strategy. They produce millions of eggs and sperm since only a small percent will actually meet, join, and become offspring. Opportunistic species are often the first to colonize a new environment with a “boom and bursts” growth pattern, with a short life cycle. They tend to “crash” when they run out of food, space, oxygen, sunlight, or whatever the limiting factors is in that environment. Examples are most insects, and corals, barnacles, clams, scallops, and oysters, who spawn and fertilize their eggs in the water. Equilibrium species use the K-strategy. The carrying capacity of the environment. These species produce much fewer offspring and usually brood them and/or take care of them in other ways. The populations of these species may first...

...article for a reader who has not read the original article. The critique begins by summarizing the article and then analyzes and evaluates the author’s research. Summaries and critiques help you learn to synthesize information from different sources and are usually limited to two pages maximum. Actions to Take 1. Skim the article without taking notes: Read the abstract. The abstract will tell you the major findings of the article and why they matter. Read first for the “big picture.” Note any terms or techniques you need to define. Jot down any questions or parts you don’t understand. If you are unfamiliar with any of the key concepts in the article, look them up in a textbook. 2. Re-read the article more carefully: Pay close attention to the “Materials and Methods” (please note that in some journals this section is at the very end of the paper) and “Results” sections. Ask yourself questions about the study, such as: o Was the study repeated? o What was the sample size? Is this representative of the larger population? o What variables were held constant? Was there a control? o What factors might affect the outcome? 3. Read the “Materials and Methods” and “Results” sections multiple times: Carefully examine the graphs, tables, and diagrams. Try to interpret the data first before reading the captions and details. Make sure you understand the article fully. 4. Before you begin the first draft of your summary: Try to describe the article...

...literature you will encounter in this class will be "The Loss of the Creature", by Walker Percy. For your preparation to the class I can summarize and give you my explanation of "The Loss of the Creature". Throughout the essay Percy tries to get across how any person with expectations or "packages" will not be able to fully accept and learn from any experience. "The Loss of the Creature" starts off with the definition of beautiful, which is a key point throughout his essay. Next, he moves in to his example of a family of tourists, and their experience (through his eyes) at the Grand Canyon. He describes his theory of the sightseer, and the discoverer; "Does a single sightseer, receive the value of P, or only a millionth part of value P" (pg 1) Value P, being the experience, and the beauty in which that person collected. Following the sightseers was a couple who stumbled upon an undisturbed Mexican Village. The couple thoroughly enjoyed their first experience, but could not wait to return with their friend the ethnologist. When they did return with him, they were so caught up in what his reaction would be; there was a total loss of sovereignty. Due to their differences of interest in the village, the couples return trip was a waste. The second part of the essay includes a Falkland Islander who comes across a dead dogfish lying on the beach. Furthermore, he explains how a student with a Shakespeare sonnet, has no chance of being absorbed by a student due to the surrounding's or...

...Alexandria Clarkson Avc6h6 English Assignment 5 04 July 2016 Dying Young In Susan McCarthy’s essay “On Immortality” she uses the three different appeals, ethos, pathos, and logos, to support her thesis on the scientific possibility of immortality. McCarthy states longevity is possible but not without consequences. She also states that the idea of longevity is something that is going to take time to achieve. She uses words like “unattractive” when talking about the idea of immortality to appeal to the audience’s emotions, Ethos, and tries to sway readers by choosing negative language. She appeals to Ethos and ensures her sources are credible and varied. She also is able to provide many different examples of experiments that are both for and against. The most effective appeal was the appeal to credibility or ethos. This is effective because it is difficult to make a scientific argument if you have people questioning you the whole time. By using credible sources, she is able to get her point across while informing the reader and providing facts to back herself up. McCarthy chooses well known examples that enable the reader to recognize the material she is explaining. Specifically, she mentions an experiment by Dr. Francis Collins, a director of the National Human Genome Research Institute, involving a group of elderly Italian mice who were engineered to be deficient of a protein called p66sch (McCarthy). McCarthy chose one of the most well known human science research projects in...

...Smallpox epidemic in Boston. He decided his biology essay would be about smallpox. Smart choice for Mitty because he seemed to be attached to the envelope, so why not choose the topic. The dead doctor would be at blame, mostly. He had decide it to be a good idea to keep scabs from the 1902 Boston Smallpox Epidemic. Many ‘what if’s’ are in question, such as, What if the doctor had not kept them? Would Mitty have ever had a topic? Would Mitty have possibly contracted the smallpox disease?. All those what if’s and thoughts run through your mind while another one does, who is to blame? His mother would be partially to blame, just not as much as the doctor. She had bought the medical textbook from the doctor and let her son, Mitty Blake, use it. If she knew what the book contained I doubt she would let Mitty near it though. Mitty keeping the scabs a secret was not the right choice to pick on his part either. Since Mitty didn’t tell anyone anything his friends and family suspected nothing, including his mother. If she knew her son was struggling she would blame herself and no one needed that so Mitty kept it to himself. Mr. Lynch, Mitty’s biology teacher, is also kind of to blame. He assigned the assignment to the class and expected many expectations which Mitty is a slacker and procrastinator so he had difficulties completing the task. Mr. Lynch and Mrs. Abram had special plans to get Mitty involved with school more so they assigned essays, one about disease and the...

...Content Structuring Structuring lesson content in order to help students organize key concepts and related details is a crucial element in a student’s learning process. The use of graphic organizers is one way to help facilitate this learning process. Graphic organizers are visual representations of ideas, information, statistics, and/or knowledge. Venn diagrams, concept maps, network trees, and sequential maps are a few examples of graphic organizers. Using graphic organizers aid students in organizing, arranging, and categorizing complex information into manageable components. According to Gary D. Borich, “An advance organizer [graphic organizer] gives learners a conceptual preview of what is to come and helps prepare them to store, label, and package the content for retention and later use.” (2007, p. 271). Extensive research suggests that the use of graphic organizers make the learning process easier to comprehend for all learners. Borich states, “Advance organizers have been found especially helpful for students from diverse culture and English-language learners…” (2007, p. 271). Organizing and introducing a graphic organizer for class use involves preparation. As an educator, it is imperative to organize and comprehend the concepts to be taught to the students. Once the information is gathered and understood, a specific learning objective can be formed. The learning objective is presented to the students in a clear and concise manner. Presenting...

...Gretchel M. Quinones HUMA 101 WORK SHOP 4 Essay Ricardo Serano Greek science and math the influence: Development of Science Long time ago, people lacked knowledge on why certain things happened. Without scientific answers, like we have today, the Ancient Greeks created their own answers about the world and an individual’s place in it. By doing the research for this essay I had learn a lot of the Greeks contribution in science and math methods. Science in Ancient Greece was based on logical thinking and mathematics. It was also based on technology and everyday life. The arts in Ancient Greece were sculptors and painters. The Greeks wanted to know more about the world, the heavens and themselves. People studied about the sky, sun, moon, and the planets. The Greeks found that the earth was round. Many important people contributed to Greek scientific thought and discoveries. Biology, a very vast and interesting topic, was studied by Hippocrates, Aristotle, Theophrastus, Dioscorides, Pliny, and Galen. These men were among the main researchers of Greek biology who contributed many ideas, theories, and discoveries to science. Some of their discoveries were observations, descriptions, and classifications of the various forms of plants and animal life. Other discussions in biology were natural selection and zoology. All living things were the basic concern of biology. Greek biologists were interested in how living things began, how they developed, how they functioned, and...

The question why only needs causes, if comparing with the past about twenty to thirty years ago, there were less people who are homosexual or bisexual than now. This research essay will provides five sections which are five main causes, it includes psychology, experience(social environment), cultural influences and individuals liking due to differences between homosexuality and heterosuxaulity Psychology and Biology The focus on brain and behavior study shows us many evidence that homosexaulity is definitely related to psychology and biology. Could homosexuality be illness if it is only about psychology because human has different idea in everything and also has difference in mental health. However, there are several studies could not find any conclusion that being homosexual is considered an illness or not. “Although dispassionate scientific research on whether homosexuality should be viewed as an illness was largely absent from the fields of psychiatry, psychology, and medicine during the first half of the twentieth century, some researchers remained unconvinced that all homosexual individuals were mentally ill or socially misfit” (Berube, 1990). In the other hand, there are many studies about genetic behavior that point out it is the main cause of homosexuality, but the question is how...
