You have been assigned the job of maintaining one population of horses exactly like they are (same genetic variety and characteristics) far into the future, while promoting genetic change in a second group. Using the two islands, drag the conditions for each of the groups onto the island in order to either promote change (evolution) or stifle it.
Miles of ocean discourage Evolving Population
Stable Population horses from attempting to swim towards the mainland.
Dominant stallions prevent other stallions from mating.
Mutations occur, but over generations these mutations do not persist.
Small population size Large population size A few horses are able to swim across the channel to join mainland herds
The gametes of the mares tend to suffer from mutation caused by certain plants on the island.
Reset Stallions and mares show no preference in mate choice.

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.
