A biologist wants to measure the effect of gene flow between populations. Which of the following investigations will allow her to accomplish this goal? 1.An investigation that determines a change in allelic frequency of a wolf population by theimmigration of a wolf from another population
2.An investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes.
3.An investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig.
4.An investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(μm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
