If a mother deer produces more milk than usual, she will likely grow
more as well. - ANSWERS-False
The majority of energy in the milk consumed by a fawn will be
converted to biomass during growth. - ANSWERS-False
During an unusually cold fall, a mother deer will face a tradeoff between
endothermic thermoregulation and milk production. - ANSWERS-True
Forget Roses, House Finches Are Red
While female house finches are brown, males can obtain a red coloration
by obtaining carotenoids (antioxidants) in their diets. This is thought to
be an honest signal of health because only the healthiest house finches
can develop into a bright red color. The males range in color from bright
red to dull yellow. Females seem to prefer the red colored males.
However, researchers find that in different environments, they see
different results. See the graphs below for different selection pressures
on red coloration.

41. The graph on the top right represents the shape of the selection curve
if redder males are producing the most offspring. - ANSWERS-False
If predators cued in on the red coloration such that the yellow males
could camouflage and the brightest males were fast enough to escape,
we would see a selection curve like the one in the top right corner. -
ANSWERS-False
The graph in the top left represents stabilizing selection. - ANSWERS-
False
If too much red coloration meant that house finches had no energy left
for reproduction, we would expect a selection curve like that on the
bottom right. - ANSWERS-False
If house finches populate an urban area with no predators, unlimited
food resources and unlimited mates, you may start to see a selection
curve like the lower right, indicating no selection on this trait. -
ANSWERS-True
