Dodos, Dinos, and Deinococcus History of A Habitable Planet Discussion
CHAPTER 17: Questions1) What kinds of landscape features are characteristic of glacial erosion?2) What kinds of landscape features are characteristic of glacial deposition?3) Consider a lecture hall filled with 100 students, 50 men and 50 women.When we say that the ratio of men to women (men/women) is 1:1 we mean that there are the same number of men as there are women.Now, if 25 women leave the room, then there are only 75 people left and the ratio of men to women would be 50/25, or 2:1. Now there are twice as many men as there are women in the room.OK, get ready to think!Consider an OCEAN that is filled with two different kinds of water molecules— H216O and H218O (This is because there are two kinds of oxygen, heavy and light, known as 16O and 18O)Answer the following questions:A) Which is heavier, H216O or H218O?B) Which is more likely to leave the ocean during evaporation. H216O or H218O?C) If the evaporated molecule gets trapped in glacial ice during cold time periods, i.e. not allowed to return to the sea, THEN which kind of water molecule becomes enriched in the remaining ocean water? H216O or H218O?4) A particular level in a deep-sea core has an unusually high ratio of 18O relative to 16O—does this portion of the core represent a global warm-period or a global cool-period?5) Look at Fig 17.6 (titled “Climate Changes During the Cenozoic”) and compare it to Figure 18.5 (“Cenozoic Vegetation/Climate”) in the next chapter. Both plots of temperature (one based on O-isotopes and one based on types of fossil plants) mark a significant cooling even in the Cenozoic. When does this cooling occur? Be as specific as possible.6) Not all climate change occurs on the scale of Milankovitch Cycles. Shorter term changes (10's to 100's of years) can involve big temperature fluctuations (1-5 degrees).What do you think could cause short-term climate change on the order of decades or centuries?CHAPTER 18: QuestionsA couple of nice web sites to accompany your textbook chapter—http://www.ucmp.berkeley.edu/mammal/mammal.html (Links to an external site.)Links to an external site.(In particular, the site above is worth poking around. It will help prepare you for the exam.)http://www.ultimateungulate.com/ (Links to an external site.)Links to an external site.1) Mammals first appear in the Mesozoic Era, which is the so-called “age of dinosaurs.”If they first appear in the Mesozoic, then why is the Cenozoic so often referred to as the “Age of Mammals”??2) Of the four mammal groups--Marsupials/Multituberculates/Monotremes/Eutheria—A) Which group do humans belong to? B) Which group no longer exists (i.e. is extinct) 3) Consider an ecological setting where we have certain predators and prey.If the prey become faster—literally faster runners—then what would you expect of the predators? Would they, over time, become faster or slower?4) Look at Table 18.1 which details some trends in mammalian evolution during the Cenozoic. Associated with the lengthening of limbs, there is a trend towards “digitigrade” locomotion.What is digitigrade locomotion and is it related to your answer to the previous question?5) Ungulates come in two general types (artio- and perrisodactyls). What are ungulates?Did the ratio of these two types remain constant through the Cenozoic?6) Compared to reptiles, WHY do mammals need to eat more frequently?CHAPTER 19: Questions1) They sound so similar—hominid and hominoid—but they're different!What is a hominid?What is a hominoid?2) How far back in the fossil record do we find the very broad group of animals known as “Primates”?How far back do we find the more specific group called hominids?3) Go on-line and do a search in order to learn about the famous Piltdown Hoax—a rather cruel trick in which a chimpanzee jaw was crudely attached to a relatively modern human skull, and then touted as an actual early human fossil!Some historians of science have pointed out that “Piltdown Man” remained in the scientific literature for an unusually long period of time, even though evidence demonstrating the absurdity of the “fossil” was quickly established.Here's the QUESTION--Why were scientists resistant to giving up on Piltdown? Why did it take them so long to say “yeah, this stupid thing is not real, it is nothing more than a hoax!” ?(Hint: They had thought that the Piltdown fossil supported an important feature of human evolultion....which turned out to be wrong!) 4) Homo sapiens refers to both genus and species. Genus=Homo, species=sapiens.Lots of different critters within the genus Homo.For example: Homo habilis, Homo ergaster, Homo heidelbergensis, Homo neanderthalensis, etc.!Today, there is only us (H. sapiens), but how far back in the geologic record does one have to go in order to find multiple co-existing species within the genus Homo? Explain.***********************The textbook is Historical Geology, Evolution of Earth and Life Through Time, 7th Edition, by Wicander and Monroe.

HCA 407 Stratford University Health Policy Non-Profit Health Clinic Essay
final Project:You are part of a team of like-mined healthcare professionals who wants to develop a non-profit Health Clinic located in a disadvantaged and crime-prone part of Miami, Florida. Before the Clinic starts operating you will need to develop a comprehensive health care policy that fully describes the Clinic's operation, goals, limitations, access to care, quality of care, financing and delivery of care, and provide evidence that the policies meet federal, state, and local policies.The document you are being asked to produce is both complex and thorough. It covers a wide array of concepts, tools and techniques of health policy, formulation, process and implementation.For this project you will create the following two deliverables:Health Policy: This is an approximately 20 page document were you describe in detail all elements of the policy that governs the operation of this new health clinic and insures safety and quality of care. As you formulate the policy be sure to keep in mind the patient population that you will most likely encounter: culturally diverse, majority either on Medicare or Medicaid, or homeless without insurance, and exposed to the ills of a crime-prone urban settings. In addition, there is a scarcity of qualified upper level medical personnel who are interested in working in this area. Security, both physical and digital, is a major issue. Lastly, remember that this Clinic is a non-profit entity.The document should include:Mission, Vision, GoalsBoard of DirectorsFinancial policiesOperational policiesSafety and Quality care policiesCare of vulnerable populations policiesStaffing policiesEthical behavior policiesAnd alignment of policies with local, state, and federal government policiesPresentation: You will be presenting the Clinic Healthcare Policy directives to the County Board of Directors for permission for the clinic and, as such, all data as well as resources used must to be appropriately referenced. The presentation should be no more than 15 minutes and be clear, concise, informative, and engaging. Use digital media but do not confine yourself to powerpoint.

Acid Titration Lab
Calculations :
calculate moles of NaOH from the average volume used in Part 1, and the given molarity.
calculate moles of HCI present originally
calculate the molarity of the HCI solution.
calculate moles of NaOH from the average volume used in Part 2, and the given molarity.
calculate moles of acetic acid present originaly.
calculate the molarity of the acetic acid solution
calculate the mass of acetic acid in 1 L of solution
Calculate the percentage of acetic acid in the vinegarQuestions :1. While doing a titration, it is permissible to use a wash bottle to wash down any material that may have splashed higher up. this would appear to increase the volume of the acid in the flask. why will it have no effect on the results?2. what was the reasoning for rinsing out the buret with NaOH solution before starting the titrations?3. By law, vinegar must be not less thqn 4% by mass acetic acid. did your sample meet these specifications?
