BIOL 1104 Exam 1 Questions With
Outlined Answers
\.you will take every exam in this class twice - Answer- yes
\.from the Uga academic honesty policy, there are a number of examples of prohibited conduct.
which one of these choices is not prohibited conduct - Answer- present information with
appropriate attribution
\.homeostasis refers to the relatively _____ state inside the body of an animal - Answer-
stable
\.imagine there are three forms of a gene (alleles) that determine coat color in squirrels (grey,
black, and white). white squirrels are eaten comparatively less often by predators in snowy
habitats than the grey or black squirrels. What can we expect will happen to the frequency of
the white coat allele in a highly snowy habitat, given the information above - Answer- the
frequency of the white coat allele will increase over generations
\.evolution is the _____ in allele frequencies from one generation to the next - Answer-
change
\.(couldn't upload image) This histogram shows two overlapping distributions of the effective
number of alleles for two types of paw paw populations. The distribution for wild populations is
shown in teal. The distribution for anthropogenic populations is shown in red. What can you
conclude from these data - Answer- anthropogenic populations tend to have lower effective
number of allele than wild populations
, \.in pea plants, purple flowers (P) are dominant to white (p) and yellow peas (Y) are dominant to
green (y). With two independent genes each having two alleles, how few squares would you
need to make a punnet square analysis of a cross between PPYY and PPYy plants? To put it
another way: how many possible genotypes result - Answer- 2
\.Mendel's experiment with pea plants convinced him that an individual plant carried how many
copies of each gene that affected a discontinuous trait (such as flower color) - Answer- 2
\.Mutation is largely a ______ process, whereas _____ is directed, non random process -
Answer- random/natural selection
\.rats were subjected to electric shock when exposed to a sweet, fruity odor to which they
normally are attracted. as expected, they developed a tremendous fear and sensitivity to the
odor. What was one unexpected results of that experiment - Answer- the offspring of the rats
in the experiment also had a fear and sensitivity to the odor
\.a reason we study and compare populations of a species is to understand how traits vary
within their environment - Answer- true
\.environments are always changing. _____ is the outcome of differential survival and
reproduction over generations. _____ is a response in individual (either physical, psychological,
behavioral, etc) to changing environmental conditions - Answer- adaptation/acclimation
\.the process of peer review differentiates the publication of scientific research from tother
types of publications (books. magazines, news, twitter, etc). Which is the following is true of the
standard peer review process - Answer- manuscripts are submitted to journals, which then
allow other experts in the field to read/review/suggest changes and ultimately accept or reject
the manuscript from publication
