Describe the organization of the human body at increasingly complex levels.

Biology homework help
Select a journal article on the subject of supplements and write a 500–700-word review of the article.  The media (newspapers, magazine articles, television news programs, and Web-based information sources) provide us with much of what we know about human biology. After taking a course on human biology, you might be interested in taking advantage of these resources for additional learning. Journal articles on a special topic are particularly informative, because they often go into depth and are a good source of current information, which you can use to continue learning or reviewing biology as a lifelong practice. Journal articles are a good source of information about current advances in a particular area of human biology, and they also highlight possible future advances in the treatment of certain conditions. Show Less Yet, with so much information available in the media, it is important to understand how to evaluate the credibility of these sources. We have all seen questionable statistics presented in the media, or information that appeared to be biased, misleading, or even inaccurate. How can we be sure we are taking in information that is objective, thorough, and accurate? Although we may not be experts, we can do our best to be informed and critical evaluators of information.  By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:
•Competency 1: Describe the organization of the human body at increasingly complex levels. ◦Discuss how supplements affect cells and body systems.  •Competency 5: Evaluate the objectivity and legitimacy of biology information found in articles and online. ◦Compare article with multiple sources of information about the same concepts. ◦Incorporate an analysis of sources into an article review. ◦Compare the main points presented about supplements, including specific areas of research and the findings.
•Competency 6: Apply biological concepts to factors related to human health. ◦Examine the role of supplements in athletics and discuss why supplements are currently unregulated. ◦Interpret whether or not supplements should undergo more stringent testing.
•Competency 7: Communicate effectively in a variety of formats. ◦Write coherently to support a central idea in appropriate format with correct grammar, usage, and mechanics, including correct APA format and citations.
You are encouraged, but not required, to use Senchina’s 2013 article “Athletics and Herbal Supplements,”

Welcome to Biology!
For your primary post, select ONE of the following discussion topics. Please select only one of the three topics listed. Using your own words, write a primary post of at least 125 words that follows the instructions. Be sure to address everything listed in the instructions. Each topic has two subtopics [a, b]; please address both of them.
Your primary post is worth up to 14 points. Also, make a substantive reply to a fellow classmate on any topic. Use your own words. You don’t need to use any sources other than the ones specified, but if you do use other sources, you must cite them.
Topic 1. Climate Change / Terrestrial Species. Watch the 7.5 minute video by Cox (2016) about how climate change affects the “species range” of terrestrial species. This video can be found in the “Instructor Insights” of Week 1. Based on the video, address the following:

  1. Describe three things you learned from the video.
  2. Explain how the video relates to the field of biology.

Topic 2. Evo-devo. Watch the video (Olsen, 2007) featuring Sean Carroll discussing the science of evolution and the field of evolutionary-developmental biology (evo-devo).

  1. Describe three things you learned from the video.
  2. Tell me what these things teach us about biology.

Topic 3. The cusp of a revolution in medicine. In a recent op-ed, Craig Venter (2017) shares his opinion that we are “on the cusp of a revolution” in medicine.
Venter also addresses the issue of human germline editing, which is something we discuss in a later part of this course. For now, let me just note that editing the human germline means making permanent changes to the DNA of eggs, sperm, or a fertilized ova. Such changes would be permanent and would be passed on to future generations.

  1. Describe three things you learned from this opinion article.
  2. Explain how this article relates to biology.

Describe how many herbivores and omnivores you added (and what they eat) in order to create an ecosystem in which all three plant species can coexist

Biology homework help
Read the Overview and launch this ecolosystem simulator. Familiarize yourself with the simulator interface. Notice that you can control which species are present in your environment initially and what the diets of each species are. The types of species possible in the program are Plants (A,B,C), Herbivores (A,B,C), Omnivores (A,B) and one top Predator. You can control the diet of each by indicating what they feed on. By setting up different starting configurations you can investigate the evolution of this simulated ecological system.
•   A. In a couple of sentences describe what happens when you start with only plants (A & B) and then all species of plants present.
•   B. Describe how many herbivores and omnivores you added (and what they eat) in order to create an ecosystem in which all three plant species can coexist. (if you cannot accomplish the survival of Plant C describe your best configuration. Describe your ecologies by identifying the species present and their diet, for instance:
Omnivore A eats Herbivore A, Herbivore A eats plant A and plant B, Herbivore B eats plant A, All plants present.
•   C. If you can accomplish part B., see if you can get all of the species to coexist. (limit your time on this entire experiment to 90 minutes)
•   D. If we assume that this simulation is a reasonable oversimplification of a typical ecosystems food web what does it tell us about biodiversity and ecology- are they robust or fragile? In general is an ecosystem’s biodiversity preserved as it responds to change?

4. Is the cross in Case 1 sex-linked or autosomal? Explain.
5. Based on the data obtained, is the most likely mode of inheritance in Case 2 autosomal or sex-linked? Explain.
6. From the data presented, what is the genotype of the parental (before the F1 generation; not shown here) generation?
7. Determine the degrees of freedom. This is the number of categories (red eyes or sepia eyes) minus one. For the data in Case 1, what is the number of degrees of freedom?
