6. The following is a type of the drug currently being tested to see if it is effective in the treatment of COVID-19.   

Anti-inflammatories/ immunosuppressives – ex. Actemra

explain how anti-inflammatories and immunosuppresives are being used to treat COVID-19 and how they work in general

Choose correct answers: Which of the following are true of nuclear receptors?

Question 7 options:

Suppose that goats have one gene that codes for color, where A is brown and a is white. The goats also have another gene that codes for height, where B is tall and b is short. If these two genes are unlinked, what is the probability that a cross between Aa Bb × Aa bb parents will produce two out of six offspring that are brown and short? Enter your answer as a decimal, rather than as a percentage.

waht is the Number ? Number:____.

1. In the MIC assay, why did it matter what the E. coli density is? (Why was a diluted culture used to inoculate the broths?)
2. The MIC assay measures inhibition, not killing. If you wanted to conduct a Minimum Lethal Concentration, how could it be done?

Hypothesis 1: Mercury in thimerosal caused neurological damage in children, and is at least partly responsible for
the increase in autism diagnoses.

Hypothesis 2: Te rate of autism incidence is not increasing, only the rate of autism diagnoses, as greater awareness
of the syndrome and increased screening of children yields more positive diagnoses of autism.

What are the observations that led to the generation of the above hypotheses? Do both hypotheses make testable predictions? How could you test them?

Given the viral life cycle pictured, identify 3 stages of the cycle which you might target with a therapeutic molecule in order to both (i) prevent or inhibit spread of the virus, and (ii) avoid affecting human cells. Explain your choice in detail in all cases.

Explain what meat allergy (or alpha-gal syndrome) is and how it develops.

A sixty year old man is found comatose. He has dry mucus membranes and a blood glucose level of 650 mg/dL but no ketones in blood. A urine dipstick test is positive for glucose but negative for ketones. What would be your diagnosis and why?

You are researching a population of brittle stars that varies in the number of legs that they produce. You survey the local population, and come up with the numbers below. Assume that the phenotypes you encounter represent the full range of possible phenotypes in this population.

1. Calculate the phenotypic variance in this trait.
2. Do the traits in this population appear to be normally distributed? Give an explanation of why this pattern might be observed.

3. Through a series of breeding experiments, you calculate that h2 for this population is 0.3. If no dominant alleles contribute to this trait, and there are no epistatic interactions involving the gene loci that control this trait, what is VE for this population?

#of legs: # of individuals:

5 ; 420

6 ; 189

7 ; 72

8 ; 5

9 ; 3
