1. A virus killed most of the seals in the North Sea (e. g., dropped the population from
8000 to 800). In an effort to help preserve
the species, scientists caught 20 seals and
used them to start a new population in the
northwest Pacific Ocean. Which of the
following mechanisms would most likely
have the most impact in this new
population?
A) Mutation
B) Non-random Mating
C) Genetic Drift
D) Natural Selection

How does the carbon cycle involve an exchange of carbon

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.
