Assume those who received folic acid had incidence of NTD equal to 2 cases per 10,000 population, and those received a placebo had a disease Y incidence of 5 cases per 10,000 population. What is the efficacy (shown as a percent) of folic acid in preventing fetal NTD based on this study? Show calculations for credit.

Dihybrid In rabbits, grey hair is dominant to white hair. Also in rabbits, black eyes are dominant to red eyes. Short hair is dominant over long hair, and curly hair is dominant over straight hair. BB = black eyes Bb = black eyes bb = red eyes GG= grey hair Gg - grey hair gg = white hair SS = short hair Ss = short hair Ss = long hair CC = curly hair Cc = curly hair cc = straight hair 7. A male rabbit with the genotype GGbb is crossed with a female rabbit with the genotype ggBb. What are the genotypes and phenotypes of the F1 generation? Genotype: Phenotype:
Does blood type influence COVID-19 symptoms? Research regarding variable presentations of COVID-19 continues rapidly. Some of this new research hypothesizes blood type influences. Initial Post Read ABO Blood Types and COVID-19: Spurious, Anecdotal, or Truly Important Relationships? A Reasoned Review of Available Data. Focus on the general concepts, as opposed to understanding every word. After completing the reading, answer the following question for your initial post: “How does blood type influence symptom variations in people exposed to COVID-19?” Use the assigned article, with appropriate APA citations, to support your position.

Skin cancer carries a lifetime risk nearly equal to that of allother cancers combined. Following is a graph [modified fromK. H. Kraemer (1997). Proc. Natl. Acad. Sci. (USA) 94:11–14]depicting the age of onset of skin cancers in patients with orwithout XP, where the cumulative percentage of skin cancer is plotted against age. The non-XP curve is based on 29,757 cancerssurveyed by the National Cancer Institute, and the curverepresenting those with XP is based on 63 skin cancers from theXeroderma Pigmentosum Registry.

Some people have a genetic predisposition for developing priondiseases. Examples are described in Table 25.6. In the case ofGerstmann-Straüssler-Scheinker disease, the age of onset istypically 30–50 years, and the duration of the disease (whichleads to death) is about 5 years. Suggest a possible explanationwhy someone can live for a relatively long time withoutsymptoms and then succumb to the disease in a relativelyshort time.

Link: Lack of RAC1 in macrophages protects against atherosclerosis - PMC (nih.gov) Could somone explain exactly what this means below? NOT HW just trying to get a better understanding on what this experiment is about. To produce mice that are deficient for RAC1 in macrophages, female C57BL/6 mice homozygously expressing the floxed Rac1 gene (Rac1fl/fl) [6] were crossbred with male mice homozygously expressing Cre under the monocyte-specific lysozyme M promoter (LC) [12]. Mice were genotyped for Rac1 deficiency as previously described

In the pathological manifestations of intestinal and brain tissues in NEC neonatal rats section of the results section the authors wrote “The histological score of intestinal tissues revealed a significant difference (P = 0.016) between normal (0 +/- 0) and NEC (2.33 +/- 0.58) groups (Table 1), which further indicated a successful construction of NEC models.” Other than saying there was a significant difference, how do you know that there was a significant difference? link to article: https://doi.org/10.1186/s12868-022-00749-1
