Alfred kinsey conducted research to determine what percentage of the population was heterosexual and what percentage was homosexual. why would he have avoided asking the question, "do you identify as gay or straight? "a. he needed to justify his research by having lots of questions. b. he believed that sexuality is a continuum and wanted to classify people more precisely. c. he believed that people would lie to him and needed to be tricked into revealing that they were gay. d. he didn't really believe in sexual orientation, but saw "homosexual" and "heterosexual" as socially constructed and constantly changing. e. he thought that there would be a large number of transgendered people in his sample.

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.
