Treatment Resistant STI Quiz 2

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

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

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

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

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

A   subject to disruptive selection.

B   a strong predictor of adult weight.

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

C   The similarities are probably due to random chance.

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

B   very different proteins

C   very different DNA

D   very similar DNA 

A   that are adaptive.

B   that are acquired in an individual’s lifetime.

C   that confer a reproductive advantage.

D   that are heritable. 

E   that reduce mortality.

A   organisms that are stronger.

B   more intricate adaptations.

C   organisms that are perfectly adapted to their environments

D   uniformity.

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 decreases the genetic variability within a population.

C  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.

D  Only choices a) and c) are correct.

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

A   its members must possess inheritable variation. 

B   it must have a small population size.

C   the mutation rate must be low.

D   it must be in an unstable environment.

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

A   STIs can be transmitted through the mouth or the anus.

B   STIs are annoying and uncomfortable but they are never fatal.

C   Genital herpes can be treated and cured with antibiotics.

D   STIs can only be transmitted through sexual intercourse. 

E   Nearly all STIs have severe and obvious ongoing symptoms.

C   None – all of these are advantages.

D   The offspring of sexual reproduction are genetically different.
