Treatment Resistant STI Quiz

A   Humans have provided the selection pressure that results in more harmful strains of bacteria. 

B   Bacteria can mutate in order to be immune to antibiotics.

C   Bacteria are becoming resistant to antibiotics much more slowly than humans can invent new antibiotics.

D   Resistance alleles in the bacterial populations in the human body are in Hardy-Weinberg equilibrium.

E   It takes decades or longer for organisms to evolve by natural selection.

A   subject to stabilizing selection. 

B   a strong predictor of adult weight.

C   not a heritable trait.

D   subject to directional selection.

E   subject to disruptive selection.

A   Divergent evolution and adaptive radiation into new niches often result in convergent evolution.

B   The basic shapes of fish, penguins, and dolphins are vestigial structures.

C   The similarities are probably due to random chance.

D   Parallel evolution is common among aquatic mammals.

E   Fish, penguins, and dolphins all faced the same physical constraints during their evolution and converged upon the same body plan. 

A   very similar DNA 

B   very different proteins

D   organisms that are perfectly adapted to their environments

E   None of the above is correct. 

A  Migration of individuals into a population generally increases the genetic variability within a population.

B  Migration of individuals into a population generally causes no change in the genetic variability within a population because it is a case of artificial selection.

C  Migration of individuals into a population generally causes that population to diverge to the extent that it becomes a new species.

D  Only choices a) and c) are correct.

E  Migration of individuals into a population generally decreases the genetic variability within a population.

B   it must be in an unstable environment.

C   its members must possess inheritable variation. 

D   the mutation rate must be low.

E   individuals must be migrating in and out of the population.
