[SOLVED] Childhood Vaccinations
Please answer the following questions after listening to the recent episode of the Diane Rehm show from National Public Radio on childhood vaccinations. What is the argument against childhood vaccinations? What are the benefits of childhood vaccinations? Are they outweighed by the negatives? What type of research is being performed to ensure the safety of vaccines? Do you believe that single-dose vaccines are better than administering vaccines in cocktails?
[SOLVED] Recreation of the Human Body
if you had a chance to recreate the human body, system to system, what would be changed, add, or improve, would we change? Add, or use bionics? Please include systems below integumentary system, muscular system, Skelton system, endocrine system, cardiovascular system, lymphatic system/immune system, respiratory system, digestive system, urinary system, reproductive system male-female, cranial areas/ senses brain, eye, ears, and mouth. The style to write is double spaced. Note that APA I don’t know what that is.
[SOLVED] Polar and Non-polar Amino Acids
What are the differences between polar and non-polar amino acids and what is the role of polarity in amino acids? What are the two types of absorption involved in amino acid absorption? Provide a 3 paragraph response.
[SOLVED] Streptococcus Pyogenes
1. Type Microorganism you have 2. Gram reaction (if any), shape, and arrangement 3. Virulence factors 4. How the organism evades the immune system 5. Disease your organism can cause 6. How your organism can spread to others 7. Ways to prevent infection 8. How your organism will be treated 9. What a nurse needs to know about your organism 10. Prepare APA format typed essay that documents YOUR understanding of the information and how it pertains to your assigned organism. APA is 12 point font Times New Roman with one-inch margins. 11. Include at least 4 APA style references from scholarly articles and resources. For each reference, you will provide an in-text citation by providing a quote or paraphrasing the author’s information.
[SOLVED] Darwins Theory
The minimum length for this assignment is 1,200 words. 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. Describe Darwins 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.
[SOLVED] Mycobacteria Tuberculosis
History and prevalence of the microbe. Characteristics of the microbe including the environment of where the bacteria grows, what are the growth requirements (will it only grow on a certain medium? Is it a halophile? Is it a thermophile?) How is the microbe currently treated in hospitals? What about countries who may not have as well-equipped facilities as the United States? What is the current research on the microbe? Are there any interesting current advancements? Any other interesting facts about the pathogen. The paper must have the following to be considered complete: You must write at least 1000 The paper must be double spaced You must use a standard font, Times New Roman. Citations must include a Reference section and In-text citations. This is a research paperyoull have a lot of in-text citations. APA is preferred.
[SOLVED] Prokaryotic and Eukaryotic
Prokaryotic and eukaryotic are the two major categories of cells making up life on earth. Both of these types require water and carbon. Describe the characteristics of water and carbon that make them important to living things in general, and to specific forms of life including plants, animals, and prokaryotes. Why is NASA looking for water on Mars? Describe the differences in prokaryotic and eukaryotic cells. How have the characteristics of each kind of cell put limitations and provided opportunities for the survival and divergence of modern living things? Why might both cell types be considered equally successful? Make sure to consider both Domains of Prokaryotes.
[SOLVED] Disease System
For your final lab assignment, I would like you to pick a clinical condition (disease, syndrome etc) that interests you. First, explain what you know about the condition and the organ system(s) that are affected by this condition. Then explain how this condition is a departure from homeostasis. By studying Human Physiology over the past few weeks, what did you learn that allows you to better understand this condition?
[SOLVED] Use of a Dichotomous Key
Classification is often done through the use of a dichotomous key, a series of binary decisions (yes/no, true/false, blue/green, rod/circle, etc) based on features of what is being classified, whether it is bacteria or candy. The attached files show two ways that a dichotomous key can be constructed for the classification of candy. In both forms, the largest distinction is placed at the top and is followed by further distinctions until all items are classified. The flow chart version is often easier to understand so start with that. The tabular format at first is more difficult to understand but works the same way except that instead of lines connecting from higher to lower keys, a series of jumps (go to’s) are used. For this assignment you will need to produce a dichotomous key for the following organisms Bacillus megaterium Corynebacterium hofmanni Klebsiella pneumonia Micrococcus luteus Mycobacterium smegmatis Proteus vulgaris Rhodospirillum rubrum Spirillum serpens Staphylococcus auerus based on their morphology and staining (use any or all of the stains used/observed in lab – simple, gram, acid-fast, spore, flagella and capsule). To construct your dichotomous key, begin by creating a table listing the organisms across the columns and their morphology and staining down the rows. Once constructed, find the row that provides the most complete division into two groups (hint: it will be what can be considered THE microbiology stain). Then move rows to sort by increasing refinement. Your first row will be the first pair in the tabular construction or the first box in the flow chart. Since the flow chart is easier to visualize, you may find it useful to create it in its entirety to check your key then convert to tabular format. If you can generate the flowchart in digital form, it can be submitted instead.
[SOLVED] Genetics and Mutation
Watch and take notes on Dr John Sanford’s November 2018 45 min. presentation to the National Institute of Health on, plus the 20+ questions and answers that follow. https://uncommondescent.com/evolution/john-sanford-gives-lecture-at-nih-on-mutations-and-human-health/ Answer the following questions: Name 2 famous geneticists who expressed grave concerns about the effects of mutation accumulation on human fitness. According to Haldane, what is the theoretical maximum rate of mutations we can sustain and still survive indefinitely? What did Kimura’s graduate student convince Dr Kimura about the true nature of “neutral mutations”? What software did Dr Sanford use to simulate the effects of mutation and natural selection upon human fitness? What evidence did Dr Sanford provide that indicates mutation accumulation is driving the human race toward extinction? What did Dr Sanford suggest to be our best plan at slowing the rate of loss of human fitness? In the Q & A session, Dr Sanford’s claim that mutation accumulation is rapidly leading the human race toward extinction. What observation and assumption did they base their claim on? In your opinion, which do you think is more reliable: (A) Dr Sanford’s evidence that mutation accumulation is degenerating the human race or (B) mutation + natural selection has given rise to and sustained complex life forms for hundreds of millions of years?
