Pick a clinical condition (disease, syndrome etc) that interests you. First, explain what you know about the condition and the organ system(s) that are affected by this condition. Then explain how this condition is a departure from homeostasis. By studying Human Physiology, what did you learn that allows you to better understand this condition?

Films 1) List the main idea you learned from the film/documentary/series and explain how you can apply what you learned to your life. 2) Identify 3-5 key concepts from the chapters assigned (chapters 1 & 2) Concepts like: religion, syncretism, ritual, sacred, magic, anthropology, etc. Make sure you first give the definition of the key concept and then give direct examples from the film (i.e. “Anthropology is defined by Stein and Stein as the study of humans in time and space (p.10) and in his lecture Wade Davis explains how anthropology enables us to “)Make sure you use a separate paragraph for each of these concepts and you highlight, bold or underline the concept.

The Golden Age of Microbiology changed medicine and microbiology forever. During this age the germ theory of disease was established, disinfectants introduced, the role of immunity established, vaccines developed, surgical techniques and microbiology culture techniques developed. Begin with Edward Jenner and end your essay with the works of Elizabeth Bugie and Rebecca Lancefield. 

Many folks think of evolution as a topic relevant only to Darwin and a few scientists. In reality, evolution touches your life every day. The cereal you eat for breakfast comes from a grain that has evolved to its current state after generations of artificial selection by humans. If you get a flu shot, the reason you have to get one every year is that viruses constantly evolve, and a vaccine that works this year may not work next year. If you wash your hands with antibacterial soap, you will kill some bacteria, but other bacteria may have mutations that make them resistant to the agent used in the soap. Evolution is going on all around us all the time; if we want to help make decisions to protect the environment and ensure a healthy future and a plentiful food supply, we need to understand how it works. Now that you have completed several modules covering various aspects of the theory of evolution, we want you to apply that knowledge to some real-word examples. For this assignment, you should 1. Open the .pdf attachment labeled Evolution, Science, and Society: Evolutionary Biology and the National Research Agenda (a project sponsored by the A. P. Sloan Foundation and the National Science Foundation in 1998). 2. In the .pdf, scroll to “How Does Evolutionary Biology Contribute to Society?” (page 5) 3. There are 6 topics listed on that page. We ask that you pick one of the following 5 topics as the subject on which you will write your paper (NOT “Understanding Humanity”): Environment and Conservation Agriculture and Natural Resources Finding Useful Natural Products Human Health and Medicine Biotechnology Select ONE of these topics and investigate it. To begin, search for the topic/keyword in the actual report (hint: use the find function in your browser / PDF reader). Look for specific examples of how evolution is related to your topic. Next, perform an internet search on your topic to find more examples and add to what you have already learned. You need to identify at least 4 specific examples related to your topic. 4. For each of your 4 examples, write a brief paragraph (3-5 sentences minimum) describing what it is and explaining how this example demonstrates that understanding the principles of evolutionary biology contributes to society. Be specific! If you describe an example but don’t make it clear how our understanding of evolution relates to that example, you will earn no points. These examples must be in your own words – do not copy and paste from your sources; this is academic misconduct/plagiarism and will be treated as such! Make sure to cite the sources that you use. For example, if your topic was “Finding Useful Natural Products”, one of the examples mentioned in the report involved the Pacific Yew tree. So your paragraph might be something like this: Finding useful natural products In the 1960s the Pacific yew was discovered to contain a substance that was useful in treating certain cancers. Sadly, the tree needed to be destroyed in order to produce enough taxol to treat one patient. This destructive harvesting threatened the existence of the Pacific yew. Luckily, by furthering our understanding of the evolutionary relationships within the yew family we discovered that a close relative of the Pacific yew, the European yew, contained a similar compound in its leaves, which allowed for easier extractions and harvests, and did not destroy the individual. Thanks to our understanding of evolutionary biology we were able to more readily produce taxol which has resulted in countless lives saved. Citation: “Drug Discovery”. Understanding Evolution. UC Berkeley. Web. 02 Feb. 2016. (provide link if source cannot be easily found) Note that because it has been provided as a sample answer, you cannot use the Pacific yew as one of your examples in your paper!

Lab 3 QUESTIONS Remember that molality (m) = moles of solute / kg solvent. So, using your data from Table 1, calculate the moles of each solute (glycerol, NaCl, and CaCl2) used in this lab by using the experimental molality and the mass (in kg) of water in each trial.. You must show all work to receive credit. Recall that the molar mass of a substance is expressed in g/mol. If we have a mass of a substance, and we know how many moles of it we have in that given mass, we can divide g/mol to determine the molar mass. So, using your experimental data from Table 1 and your answer to the previous question, calculate the molar mass for each solute. You must show all work to receive credit. Calculate the percent error for your experimental values for each solute. Is your percent error value relatively constant with each trial? If so, what might this indicate (include accuracy and precision as part of your answer)? You must show all work to receive credit. What are some possible sources of error in your experiment? Discuss at least 3 in detail. Which solution of salt (NaCl or CaCl2) may be better to salt the roads? Why? (HINT: Don’t just focus on the final freezing point in each case—consider all your data and how it may be tied to efficiency and economic factors.)

The discovery of the antibiotic Penicillin in the 1920s made a big impact on human history. Not only did it provide a cure for bacterial infections that were once deadly, but it also led to a golden age in the discovery of new antibiotics. The great benefit of these drugs is that antibiotics inhibit the growth of bacterial cells or kill them outright, and yet, on the whole, do not harm eukaryotic cells. Answer BOTH of the following questions: Given the following list of antibiotics and their targets, explain how each stops bacteria without harming human cells. Base your analyses on the differences between eukaryotic and prokaryotic cells. Considering the targets of these antibiotics, explain why antibiotics in general would not be useful for treating a viral infection.AntibioticTargetPenicillinBlocks cell wall synthesisTetracyclineBlocks protein synthesis by binding to the 30S Unit of the ribosome Chloramphenicol Blocks protein synthesis by binding to the 50S Unit of the ribosome SulfonamidesInhibit folic acid synthesisVancomycinBlocks cross-linking of the peptidoglycan in the cell will read this to enhance your understanding of the differences between prokaryotic and eukaryotic cells: How do antibiotics kill bacterial cells but not human cells?
