Sociology final reflection papePAPER: THE REMEMBRANCE PROJECTYou will write a 2-3 page reflection as the final for this course, thus, 20% of your grade in this course depends on the precision, depth, and creativity demonstrated in this paper. Having dived into the study of society and discussed differences across hundreds of variables, the time has come to think about the one variable which is incontrovertible across time and space – death.Every person who has ever lived has had to contend with the facts of existence and no fact is more immutable than all who live will eventually pass away. The existential anUnit 7 DiscussionFungal PathogensChoose any one of the fungal pathogens and discuss its appearance, staining reaction, culturecharacteristics, disease caused, and epidemiologicalcharacteristics (where is it common, who is at risk).Unit 8 DiscussionDisease TransmissionExplain how nosocomial infections are becoming serious health threats within healthcare system. Discuss the known methods used for breaking the chains of disease transmission.Propose a way to educate the general public on their role in preventing disease transmission.Each discussion must be at least 100 wordsgst induced by such realizations often follows on the heels of a close friend or loved one passing away. Of course, just because all people pass away doesn’t mean they agree on what constitutes a life well lived. It is my hope that all of you will live a life that you can consider to be “well-lived” whatever that means to you personally.I think part of living such a life stems from having thought about what we value about ourselves and others, what we are most proud of and ashamed of, and what we hope our legacy will be after we are gone. To facilitate such thinking, I have created this journal exercise based on two thought experiences. All I ask is you sit there and think deeply about each experiment for a few minutes and then commit yourself to writing no less than one page about each one.Thought Experiment #1:Imagine that one of your close friends is talking to one of their friends, someone who knows nothing about you and who has never met you before. Having never encountered you before, this friend of your friend has no idea what you look like, what your voice sounds like, how you dress, what your beliefs are etc. How would you WANT your friend to describe you to their friend?Thought Experiment #2:Imagine that you lived to be 90 years old and passed away while you were sleeping. One hundred years after you die, a researcher begins writing a biography about your life. What would the researcher need to emphasize for you to feel like the biography did a good job of capturing your life?Again, please read the thought experiments carefully and think about them for several minutes before starting to write. You need only include half a page for each experiment, although you are certainly welcome to write as much as you want. The paper is due December 6. 

Please answer only four (4) of the questions below as completely as possible.  Answers to the questions can be found in Introduction to Ocean Science 4th Edition, by Douglas Segar as the questions come from the Critical Thinking Questions in the text.  25 points each.   here is the link to the textbook  http://www.reefimages.com/oceansci.php  (Links to an external site.)  I expect that to answer each question completely, your answer should be between 100 and 200 words in length, but the choice is yours. A few words is not likely to provide a sufficient explanation.   You are sailing across the water into an almost regular swell that comes from directly ahead of you. Suddenly you notice that the same swell now appears to be coming at you from two slightly different directions at a small angle from each side of the boat’s bow and the wave pattern ahead looks confused compared to the smooth swell you were sailing on a few minutes before. What are you seeing, and why? Should you be concerned? Chapter 9 In the Hawaiian Islands the youngest island, Hawaii, is the biggest, has sandy beaches along the smallest fraction of its coastline, and has more black sand beaches than the other islands. Oahu, which is older than Hawaii, is smaller, has a greater fraction of its coastline occupied by beaches, and does not have black sand beaches. Kauai, which is older than both Oahu and Hawaii, is smaller than either of these other islands, has the largest fraction of its coastline occupied by beaches, and also does not have black sand beaches. Explain why this progression of island characteristics with age occurs. (These processes are described individually in several different chapters of this text.)  Chapter 11 If you measured the dissolved oxygen concentration carefully in the photic zone during a spring bloom of phytoplankton, describe how you would expect it to change over 24 h and why. Would the changes in concentration during the 24 h be different at different depths within the photic zone? If so, describe how and why.  Hint:  First list and explain the important factors that control diurnal variations and then explain the result of these processes. Chapter 12 Is it likely that a global climate change in which the Earth’s atmosphere warms by several degrees will alter the frequency or intensity of dinoflagellate blooms? Why? Is it likely that the frequency and geographic extent of periodic anoxia in coastal waters will change? If so, how and why? Chapter 13 The temperature and salinity of the abyssopelagic environment vary little with latitude or from ocean to ocean. This environment is also uniformly dark and the pressure uniformly high. Does this mean that, if we were able to sample every species in a cubic kilometer of deep-ocean water, we could be certain that we had sampled a large majority of all abyssopelagic species that exist in the oceans? Why or why not?  Chapter 15 Coral reefs and kelp forests both have high species diversity compared to some other ocean ecosystems. What are the possible reasons for this high diversity?  Chapter 15 Describe the principal sources of petroleum contamination in the oceans. Discuss what would probably cause more pollution of the oceans: production of oil from drilling platforms in U.S. coastal waters and transport of the oil ashore in seafloor pipelines, or purchase of oil from foreign suppliers and transport to the United States in oil tankers.  Chapter 16

There are actually several categories of viruses. Antivirus software makers typically categorize viruses according to the way they spread from one computer to another, but other methods of categorization are also used. Go online and learn about the different categories of viruses. Pick ONE of the categories to describe and submit and give an example
