Instruction: Read the assigned articles. Submit a one page either in MS Word or pdf format.Please write clearly and be succinct.I have the following research question:To what extent does COVID-19 in pregnancy alter the risks of adverse birth outcomes such as low birth weight, premature birth, and infant death compared with pregnant individuals without COVID-19?Do you recommend to use relative risk (RR) or odds ratio(OR)? Why? Explain.
OverviewIn the last week, we talk and discuss the macromolecules, and you identify the uses of some of them, the befits, and the side effects of its overconsumption. Perhaps, not all the time we are aware that indirectly we are over consuming some of these substances (steroids and hormones).DirectionsRead the next articles:1. The hormones and steroid in our food (Links to an external site.) https://www.caasn.com/ultimate-truth-about-hormones-antibiotics-in-foods.html2. Regulations of labeling food by USA (Links to an external site.)https://www.fda.gov/drugs/drug-safety-and-availability/fda-approves-new-changes-testosterone-labeling-regarding-risks-associated-abuse-and-dependenceA. Go to the refrigerator and pantry room, and check the food that you consume over the week. In the label, you will find if the product contains or not hormonesWrite a short paragraph (minimum 350 words) where you debate the use of hormones and steroids to grow the food that we eat. In your paragraph include if you think the published concerns are true or not.B. Then provide two example on how your classmates can use the concepts learned in this class in their lives . Minimum of 100 words per example in your reply.

Discussion: Pesticide and Antibiotic ResistanceViral diseases, such as HIV, SARS, and Ebola strike fear in the hearts and minds of those who understand the nature of these illnesses. Every year, people throughout the world visit medical clinics to receive vaccinations to protect them from seasonal influenza, another kind of virus. Deadly viruses and bacterial infections are among the evolving enemies to which the title of Chapter 11 in your course text refers. How do these enemies evolve? What makes them especially dangerous?For the Discussion, you learn about the evolving enemies known as pesticide and antibiotic resistance and propose a strategy for addressing one specific resistance example.To prepare for this Discussion: Think about the title of Chapter 12: An Evolving Enemy and consider this question: To what enemies does the title refer, and how did they evolve? As you review Chapter 12, also focus on the following:o What the term resistance meanso How resistance is related to natural selectiono The impact that different forms of resistance may have on human health You may consider your personal knowledge or experience regarding pesticide or antibiotic resistance. For example, you may be aware of a news story about a troublesome insect that is difficultto control with pesticides. Or, you may be aware of a friend or acquaintance that contracted an infection that did not respond well to antibiotics. You may draw upon your knowledge and experience to narrow your search for a topic for this Assignment. Conduct additional research, focusing on either pesticide or antibiotic resistance. Choose one particular example of resistance to address in the Discussion. This weeks OptionalResources suggest websites where you could start your search. Based on what you have learned about resistance and on the information you have gathered during your research, consider strategies that could address the resistance.http://www.nationalgeographic.com/http://www.sciencemag.org/http://www.scientificamerican.com/http://www.sciencedaily.com/Post a proposal (at least two paragraphs long) for a strategy to address the antibiotic or pesticide resistance you selected. Your proposal should include the following: A brief description of the resistance A brief explanation of when and how the resistance occurred A description of the impact of the resistance on human health A strategy to address the impact of the resistance, including reasons why this strategy would be useful References to at least two sources outside the Required Resources All references cited in APA format
write about reproductive isolation and the 3 typesEssay assignment guidelines:For this assignment, be sure that you follow the standards of academic writing. The assignment consists of a 1-page essay about a topic of your choice based on the lectures covered in midterm 2 (lectures 11-17). Your essay will require a brief introduction, a concise and focused claim about the topic selected, two to three main points you will address, solid reasoning, and textual evidence along with an explanation of its significance. Worth: 2 point bonus towards Midterm 2 overall grade (out of 15 points).Requirement: Single-spaced. Times New Roman 12-point font. All citations will be MLA parenthetical citation. Include an additional References page.Citing sources: correct and complete citation of sources is vital. Failure to properly cite your sources amounts to plagiarism. For example, in-text citations should look like this:
Instructions for the BYS 318 Vertebrate ReproductionThe assignment centers on an analysis of a recent article from the journal Science, Rapid speciation via the evolution of pre-mating isolation in the Iberá Seedeater by Turbek et al. The article is available in the Files tab of Canvas. Notice that the structure of this article places Materials and Methods at the end. It is not necessary to read the M&M closely (were not concerned about the details of analyzing genomes), but you should pay attention to reported Results and generally why. I would expect that to fully discuss the findings of this research in context will require about 2000 words.The title of the article tells you what this assignment is about: the evolution and maintenance of pre-mating isolation in a bird. Your assignment is to describe how this pre-mating isolation functions and may have originated, and compare these mechanisms to what weve read about this semester. The authors examine the evolutionary and behavioral relationship of two very similar species of bird from Argentina. You must consider and compare the authors conclusions to findings by authors with other animals in readings in this class this semester. In particular, you should consider: Assortative mating; Various possible aspects of sexual selection such as male plumage, song, territoriality (this includes evidence for color patterns in light wavelengths not visible to humans); Significance of the pattern of extra pair copulations found; Chromosomal linkage of sexual selection related genes, especially on the Z chromosome; The significance of genetic similarities and differences between the two species, and genomic techniques used; Why might the above observations create reproductive isolation, even those these two species are syntopic (have completely overlapping ranges and habitat usage)?In short, Im asking you to write a comparative synthesis of evidence presented on the seedeaters compared to work and concepts weve read about this semester. This could be along the lines of, how would think Badyaev and Qvarnstrom would interpret these findings, how does this work compare to the findings of Tuttle with white throated sparrows, would the findings about sex linkage in poeciliid fishes be relevant or informative to this research, does the paper on complex phenotypes in salmon by Thompson et al. inform Turbek et al.s findings. You can and probably should reference ideas by theoreticians as Fish and Trivers to place the article findings in correct context.Jargon:SNP, single-nucleotide polymorphism: A difference of nucleotide found at a specific sequence position in DNA, useful for characterizing relatedness and evolutionary divergence.PCA, principal components analysis. A commonly used statistical technique for ordination with a data set about different individuals or species, how do you rank their similarity or difference.FST, the fixation index (FST) is a measure of population differentiation due to genetic structure. It is frequently estimated from genetic polymorphism data, such as single-nucleotide polymorphisms (SNP) or microsatellites. Its reported on a scale from 0 to 1, with a value of 0 meaning total mixing, and a value of 1 meaning total separation.
