Below are the questions for the exam with the choices of answers:
Question #1
A Humans have provided the selection pressure that results in more harmful strains of bacteria.
B Bacteria are becoming resistant to antibiotics much more slowly than humans can invent new antibiotics.
C Bacteria can mutate in order to be immune to 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.
Question #2
A subject to disruptive selection.
B not a heritable trait.
C subject to stabilizing selection.
D a strong predictor of adult weight.
E subject to directional selection.
Question #3
A Fish, penguins, and dolphins all faced the same physical constraints during their evolution and converged upon the same body plan.
B The similarities are probably due to random chance.
C Parallel evolution is common among aquatic mammals.
D Divergent evolution and adaptive radiation into new niches often result in convergent evolution.
E The basic shapes of fish, penguins, and dolphins are vestigial structures.
Question #4
A very different proteins
B very different DNA
C none of these, their is no relationship between DNA and relatedness
D very similar DNA
Question #5
A that confer a reproductive advantage.
B that reduce mortality.
C that are heritable.
D that are acquired in an individual’s lifetime.
E that are adaptive.
Question #6
A uniformity.
B organisms that are stronger.
C more intricate adaptations.
D organisms that are perfectly adapted to their environments
E None of the above is correct.
Question #7
A Migration of individuals into a population generally causes that population to diverge to the extent that it becomes a new species.
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 Only choices a) and c) are correct.
D Migration of individuals into a population generally increases the genetic variability within a population.
E Migration of individuals into a population generally decreases the genetic variability within a population.
Question #8
A the mutation rate must be low.
B it must have a small population size.
C individuals must be migrating in and out of the population.
D its members must possess inheritable variation.
E it must be in an unstable environment.
Question #9
A STIs can only be transmitted through sexual intercourse.
B STIs are annoying and uncomfortable but they are never fatal.
C Genital herpes can be treated and cured with antibiotics.
D Nearly all STIs have severe and obvious ongoing symptoms.
E STIs can be transmitted through the mouth or the anus.

B uterus; ovary
C cervix; uterus
D vagina; uterus
E uterus; oviduct
Question #12
A seminal vesicles
B urethra
C bulbourethral glands
D prostate
E epididymis
Question #13
