Treatment Resistant STI Quiz

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

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

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

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

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

A   a strong predictor of adult weight.

B   subject to disruptive selection.

C   subject to stabilizing selection. 

D   not a heritable trait.

E   subject to directional selection.

A   Parallel evolution is common among aquatic mammals.

B   The similarities are probably due to random chance.

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

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

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

A   very different DNA

A   that reduce mortality.

B   that are heritable.

E   that are acquired in an individual’s lifetime.

A   organisms that are stronger.

B   uniformity.

C   more intricate adaptations.

D   organisms that are perfectly adapted to their environments

E   None of the above is correct. 

A  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.

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

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

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

E  Only choices a) and c) are correct.

A   it must be in an unstable environment.

B   its members must possess inheritable variation. 

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

D   the mutation rate must be low.

E   it must have a small population size.
