address questions 1, 2, and 3 below Use standard English grammar and spelling  Topic The studies of fossil records indicate that current insects evolved from giant ancestors. Watch the video titled “The Age of Giant Insects” to learn more about insect evolution. Some scientists argue that the era of giant insects ended as the levels of atmospheric molecular oxygen declined; others stated that as birds conquered the skies, they outcompeted larger insect species. To learn more about this passage in evolutionary history, read the article titled “Reign of the giant insects ended with the evolution of birds” available at the Indiana Public Media website.  Link to the video titled “The Age of Giant Insects” https://youtu.be/-wQLKMUWANg Link out the article titled “Reign of the giant insects ended with the evolution of birds” https://news.ucsc.edu/2012/06/giant-insects.html  Questions 1.  Postulate a hypothesis to explain the disappearance of giant insects during evolution?  2.  Explain the evidence that supports the stated hypothesis. 3.  Proposed at least one experiment to test the stated hypothesis.

Diversity, Benefits and Detriments of Microbes Microbiology is both a basic and an applied science. It is not a single subject! It has many areas of specialization, including bacteriology, mycology (study of fungi), phycology (study of algae), virology, medical microbiology & immunology, public health, food microbiology, biotechnology, microbial genetics, and cell & molecular biology. In this assignment, we will discuss some of the various disciplines associated with microbiology and the beneficial microbes associated with them. Feel free to download the  Week One Discussion  assignment instructions and  Grading Rubric .

Figure out the vitamin deficiency or toxicity from which the patient is suffering from. Explain what made you draw conclusions. What is the normal role of the vitamin in the cell / body? Examples Mary and the red tounge While working in an extremely impoverished area of the world where the primary (and some days, the only substantial) food source is corn, you are approached by Mary, a young woman who has the largest, reddest tounge you’ve seen you agree to examine her because she complains of other symptoms. During the examination, you notice a rash that is particularly prominent on the areas of her body most often exposed to sun, her neckline and hands. The woman also complains of feeling depressed and apathetic, suffering from memory loss, and having frequent diarrhea. Answer : I suspect that Mary has a vitamin B3 (Niacin) deficiency and is suffering from pellagra. The key symptoms that lead me to this conclusion are her red tounge, rash in sun – exposed areas, her diarrhea, and confusion. I can differentiate the niacin deficiency from a riboflavin deficiency ( which also has a red tounge) because of the rash, diarrhea, and the clue that Mary eats a lot of corn. Corn contains niacin that is tightly bound to other proteins ; however, the niacin can be released if corn is exposed to alkaline conditions before consumption. 1. You where tasked by your mother to visit your cousin who had given birth at home to a beautiful baby girl, named Suzy upon arriving at her home you saw blood oozing out from suzy’s mouth and nose.

Prior to beginning work on this discussion forum, please read the article by Barnham (2015), Quantitative and Qualitative Research: Perceptual Foundations, and the article by Rutberg and Bouikidis (2018), Focusing on the Fundamentals: A Simplistic Differentiation Between Qualitative and Quantitative Research Links to an external site. . Watch the Qualitative vs. Quantitative  (Links to an external site.)  video, and participate in the interactivity How to Read a Scholarly Article  (Links to an external site.) , as well as the embedded video Identifying and Finding Quantitative and Qualitative Research  (Links to an external site.) . Refer to the APA Formatting Template  (Links to an external site.)  to help you correctly cite journal articles. This discussion forum is the first part of a two-part integration. The peer and instructor feedback you receive in this discussion forum will be integrated and submitted in this week’s written assignment. You must provide feedback on your peers’ initial posts by Day 5 of this week. Begin to gather background information about the topic of interest and the research focus you identified in Week 1. This is the beginning of developing an understanding of the topic and a prelude to narrowing the topic. Identify three peer-reviewed academic journal articles that report on qualitative research studies that address the research topic or research focus of interest to you. In an initial post of at least 300 words that incorporates and cites information from at least two required resources, Identify and provide a complete APA citation for three articles that report on qualitative research studies that address your research topic or research focus. Consider accessing the Ashford Writing Center’s Formatting Your References List  (Links to an external site.)  for more on completing a complete reference citation. Append your three articles to your initial discussion form post by Day 3. The simplest way to post more than one file to a Canvas discussion is to zip the multiple files together and then upload them as a single file in your discussion post. Follow the How to Create and Open Zip Files on PC and Mac  (Links to an external site.)  for step-by-step instructions for zipping and unzipping files on either a PC or a Mac. Identify the characteristics of each article that tell you the study is a qualitative research study, and not a quantitative research study, citing at least two required resources. Assess how these three studies are useful in helping you develop a better understanding of your topic of interest or your research focus, and what you learned from each study. Guided Response: Answer any questions your instructor has about your initial post. Review several of your classmates’ posts, prioritizing those who have not received feedback, and respond to at least two of your classmates’ posts by Day 5. Each of your responses to your classmates should be at least 100 words in length. Indicate whether you agree that the studies identified by your classmate are qualitative research studies. Provide specific information to reinforce your assessment. Reflect on your classmate’s appraisal of the usefulness of each study. You are encouraged to post your required replies early in the week to provide opportunities for interaction and further discourse within this forum. Continue to monitor the discussion forum through Day 7, and respond with robust dialogue to anyone who replies to your initial post. Compile your instructor’s and classmates’ feedback and navigate to this week’s assignment to complete Part 2.

Darwin was not the first to consider evolution as a process, but he did come up with the first effective explanation for how it happens. In a 1-2 page Word document, describe Darwin’s theory of evolution by natural selection. Explain how this theory was a major advance over prior ideas as to how organisms changed over time. Give evidence in support of evolution and describe the driving forces for evolutionary change.

Read through the instructions prior to beginning this assignment. Select a particular historical event that you have encountered in the course of your research for your term paper.The subject of your timeline entry does not need to be an ‘event’ per se. It could feature a historical figure or institution, but it should explain what this person did or what happened in the institution named. Try to make the subject of your entry as specific as possible. For instance, rather than the medicine in World War I, you might look into Harold Gillies’s establishment of a unit in Queen Mary’s hospital dedicated to reconfiguring facial injuries sustained in the war. Describe the event. Be sure to indicate its relevance to medical history and to situate the event in its broader social or cultural context. Seek factors within this context that may help to explain why the event occurred when and where it did. Your description and analysis must be at least 250 words in length. To receive credit, you must also include your own name at the top of your description. Include an image relevant to the specific subject of your entry or its broader context if one is available.The Wellcome Collections and Wikimedia Commons are both fine sources of copyright-free images. You still must attribute the image according to the credit line listed on the website and provide a link to the image. Cite any sources of information you used in preparing your timeline slide with a complete bibliographic entry. Please use either APA or Chicago formats for your citations.
