Describe what happened to beaver colonies after 1995 (when wolves were reintroduced). Then describe the relationship between the number of beaver colonies and the willow tree ring area.

Decreases.

Explanation:

Decrease occurs in beaver colonies when wolves were reintroduced in the area because wolves feed on beaver and as a result, the population of beaver decreases. There is a direct relationship between the number of beaver colonies and the willow tree ring area because willow tree is a source of food for beavers so if willow tree are more in the area, more food available for the beaver and they will increase in number.

i believe it is c: genes for body color and wing size are inherited separately from each parent.
