Answer:
brown in summer, grey in winter -> camouflage from predators
storing fat during the summer -> gives them extra energy in the winter when there is less food
antlers with forward projections -> allows them to dig in the snow to uncover more food sources, also good for fighting predators
widely spaced hooves -> easily walk on snow and to dig for more food
migrate in herds -> find new area for more food & escape extreme weather, predators, and pesky bugs
Explanation:
We know that Hardy-Weinberg conditions include the following equations:

where 
And where p = dominant, and q = recessive; this means that
is equal to the homozygous dominant,
is the heterozygous, and
is the homozygous recessive .
So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of
or 0.04. Let that equal our
value.
So when we solve for q, we get:


Now that we have our q value, we can use the other equation to find p:



So then we can solve for our heterozygous population:

This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:

So now we know that there are 32 heterozygous cats in the population.
