Treatment Resistant STI Quiz

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

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

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

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

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

A   subject to stabilizing selection. 

B   subject to directional selection.

C   subject to disruptive selection.

D   a strong predictor of adult weight.

E   not a heritable trait.

A   The similarities are probably due to random chance.

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

C   Parallel evolution is common among aquatic mammals.

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

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

A   none of these, their is no relationship between DNA and relatedness

B   very different DNA

C   very different proteins

D   very similar DNA 

A   that are heritable. 

B   that are adaptive.

C   that reduce mortality.

D   that confer a reproductive advantage.

E   that are acquired in an individual’s lifetime.

A   more intricate adaptations.

B   organisms that are stronger.

C   uniformity.

D   organisms that are perfectly adapted to their environments

E   None of the above is correct. 

A  Only choices a) and c) are correct.

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

C  Migration of individuals into a population generally decreases 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  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.

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

B   it must have a small population size.

C   it must be in an unstable environment.

D   the mutation rate must be low.

E   its members must possess inheritable variation.
