Aplant grows faster and fuller due to large amounts of fertilizer. if the plant cross-pollinates with another plant later, how will the use of fertilizer on the parent plant affect the plant’s offspring? . a) all of the offspring will be taller than average because the parent plant’s genes were affected.. b) some of the offspring will be taller than average because some of the alleles were affected.. c) the height of the offspring will not change because the parent’s genes did not change.. d) the height of some of the offspring will be taller if the other parent plant was also fertilized.

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.
