Student Instructions For each assignment, you will use the M.U.S.E. link to complete the lab. Access the M.U.S.E. by clicking on Learning Materials. https://class.aiu-online.com/_layouts/MUSEViewer/MUSE.aspx?mid=3319400 In this lab, you will determine how an invasive species—the zebra and quagga mussel—affects other species in the freshwater lake. Use the animation to help you come up with an answer to the following: Why do you see increases and decreases in the invasive species population? What are the implications associated with these alterations to the ecosystem as a whole? The Effects of Zebra and Quagga Mussels Introduced into a Freshwater Lake As you have learned, population dynamics are caused by the biotic potential of the population and the effects of environmental resistance. When there is minimal environmental resistance impacting a population, it will exhibit a population explosion. One reason for minimal resistance could be factors that no longer regulate a population (e.g., predator decline or resource increases). Another reason for a population explosion is the introduction of an invasive species. Invasive species are species foreign to an ecosystem and are not immediately regulated by the environmental restraints of the particular ecosystem that they invade. This in turn allows their populations to grow seemingly uncontrolled and to displace other indigenous populations. Examples of such an invasive species into North America are dreissenid mussels, commonly known as zebra and quagga mussels. Their introduction into the Great Lakes has caused economic hardship and a reorganization of the ecosystem. This has led, in part, to pollution-causing effects that can be linked to an alga known as Cladophora. Ecosystems are webs of intricately balanced interactions, what happens when a new species is introduced that uses a disproportionate share of the ecosystem’s resources? Using the M.U.S.E. link, review the background information and animation to complete your report. Use the Lab 5 worksheet for assignment instructions and data collection.
We know that exercise is very important for our overall health in general but why is exercise so important for our muscles? After researching this subject please share with the class, in your own words, why you feel exercise is so important for our muscles and what will happen to our muscles if we don't exercise.
Your assignment is to write a 2-3 page essay in which you address the scenario below. Suppose that you have a house guest from another country. He is curious about the lifestyles that we tend to lead in the United States. He wants to know why there seems to be such a big problem with nutrition and lack of exercise. Explain to him why nutrition and exercise are important to the health of our society as a whole. Case assignment expectations: Use information from the modular background readings as well as any good quality resource you can find. Please cite all sources and provide a reference list at the end of your paper. LENGTH: 2-3 pages typed and double-spaced. The following items will be assessed in particular: 1. Your ability to explain why lifestyle factors such as nutrition and exercise are important to the health of a society 2. Some in-text references to modular background readings (APA formatting preferred) Be sure that your opinion is justified with evidence from the literature. Try to use several scholarly references for each assignment. All references should be cited properly in the text of the paper as well as at the end. Please limit your response to 3 pages maximum. Assignments are due on the Monday after a module ends.
Select one (1) composition by Tchaikovsky that you enjoy. Describe the music and subject matter of that work, and explain why you enjoy it.
Personal Autonomy and Health Policy Choose a current health policy issue or law that has ongoing relevance in public health. Some options include, but are not limited to, banning trans fats in local municipalities, controlling the size of sugary drinks sold in restaurants, requiring nutrition information on menus, indoor and outdoor smoking bans, removing sugary drinks from schools, or mandating vaccines for health care workers or children entering school. Describe why the chosen policies or laws are controversial. In your response, discuss how these policies affect personal autonomy (the cost to the individual) to benefit society. Provide a professional statement* on why these policies and laws are important to the overall health of the community. *Personal and professional opinions may or may not align. It is very important in your employment to be able to provide a professional opinion, regardless of how it aligns with your personal beliefs. Professional opinions are based in research and fact and reflect the beliefs of the organization as a whole and all those who work for the organization.
