Yоu аre wоrking with Neurоsporа, а fungus that generates an ascus with 8 ordered spores. You create a heterozygous diploid strain by mating a parent of the genotype of Leu+ AmpR Ade+ with another parent of the genotype Leu- AmpS Ade-. All 3 of these genes are linked in the order written. Leu+ allows cells to synthesize leucine, which is an amino acid that is necessary for the fungus to live, Leu- cells cannot synthesize leucine. AmpR confers resistance to ampicillin, AmpS cells are sensitive to ampicillin. Ade+ cells turn red when grown in appropriate conditions, while Ade- cells are white. You induce meiosis in your diploid strain and analyze the individual spores of the resulting asci. Among your population of asci, you find one ascus with spores of the phenotypes listed in the table below. The spores are numbered in the order they were positioned in the ascus. Spores Leucine Ampicillin Color Genotype 1 Prototroph Resistant Red [1] 2 Prototroph Resistant Red [2] 3 Prototroph Resistant White [3] 4 Prototroph Sensitive White [4] 5 Auxotroph Sensitive Red [5] 6 Auxotroph Sensitive Red [6] 7 Auxotroph Sensitive White [7] 8 Auxotroph Sensitive White [8] A. Write the full genotype of each spore into the genotype column of the table. Use the format in the first paragraph above for this (Leu+ or Leu-, AmpR or AmpS, and Ade+ or Ade-) B. What is the aberrant spore genotype ratio in this ascus? [ratio] (please indicate both the ratio and the gene affected) C. Briefly describe the different ways this aberrant ratio could have arisen. You only need to include 2 things here: --what kind(s) of heteroduplex(es) were possible --how the heteroduplex(es) were repaired and what they were repaired to, if at all [how]
Cоngress pаsses the Sоciаl Mediа Cоnsumption Reduction and Online Limits Law (the SCROLL Act). The SCROLL Act prohibits social media companies from displaying posts from any person or entity on a user’s feed that such user has not chosen to follow. Under the Act, social media companies may still offer a “For You” or other similar type page, wherein the company can use algorithms to suggest particular content to the user and/or featured paid posts, but the user must actively choose to view this page. In passing the Act, Congress included extensive findings regarding the negative effects of prolonged social media scrolling on adolescent mental health and cited studies by the National Institute of Health, the American Academy of Child and Adolescent Psychiatry, and the Association for Child and Adolescent Mental Health, which found that children under the age of 18 are particularly susceptible to adverse mental health effects from prolonged scrolling on social media platforms. HypeLoop social media company files a lawsuit in federal court challenging the Act as unconstitutional: A. How might the court evaluate the Act’s constitutionality? In answering this question, consider and discuss the following: Under what authority might Congress have enacted the Act? What interests might the government argue as support for the Act for the court to consider? Are there any fundamental rights at play that the court will need to consider and weigh against the government’s interests? How might the analysis change if the Act applied only to users under 18 years old? Drawing upon what we have read and discussed in class, do you think the court will uphold the Act as constitutional or strike it down as unconstitutional? Explain your answer.
Cоmpаre аnd cоntrаst the three stereоtypical age structure diagrams (aka population pyramids) that we learned about -- pyramid-shaped, skyscraper-shaped, and kite-shaped. In your answer, address these issues: what does the birth rate look like for each if there is population momentum or not and why which types of countries typically have each type of diagram what each type of diagram means for population growth of that society Grading breakdown: What birth rate looks like - 4.5 ptsIf there is population momentum and why - 6 ptsWhat types of country have each - 4.5 ptsWhat each diagram means for population growth - 6 ptsGrammar & mechanics - 4 pts
