Below are the questions for the exam with the choices of answers:
Question #1
A It takes decades or longer for organisms to evolve by natural selection.
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 Bacteria are becoming resistant to antibiotics much more slowly than humans can invent new antibiotics.
E Resistance alleles in the bacterial populations in the human body are in Hardy-Weinberg equilibrium.
Question #2
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.
Question #3
A The basic shapes of fish, penguins, and dolphins are vestigial structures.
B Divergent evolution and adaptive radiation into new niches often result in convergent evolution.
C Parallel evolution is common among aquatic mammals.
D The similarities are probably due to random chance.
E Fish, penguins, and dolphins all faced the same physical constraints during their evolution and converged upon the same body plan.
Question #4
A none of these, their is no relationship between DNA and relatedness
B very different DNA
C very different proteins
D very similar DNA
Question #5
A that are heritable.
B that are acquired in an individual’s lifetime.
C that confer a reproductive advantage.
D that are adaptive.
E that reduce mortality.
Question #6
A organisms that are perfectly adapted to their environments
B more intricate adaptations.
C uniformity.
D organisms that are stronger.
E None of the above is correct.
Question #7
A Only choices a) and c) are correct.
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 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 individuals must be migrating in and out of the population.
C it must have a small population size.
D its members must possess inheritable variation.
E it must be in an unstable environment.
Question #9
A Genital herpes can be treated and cured with antibiotics.
B STIs can be transmitted through the mouth or the anus.
C STIs are annoying and uncomfortable but they are never fatal.
D STIs can only be transmitted through sexual intercourse.
E Nearly all STIs have severe and obvious ongoing symptoms.

C testosterone; menstruation
D none of these is correct
E testosterone; ovulation
Question #11
A uterus; oviduct

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