the diagram shows how a random error in dna replication results in a point mutation.

b.
the diagram shows how crossing over results in new genetic variations.

c.
the diagram shows how changes in nitrogen bases may be passed on to offspring during meiosis.

d.
the diagram shows how uv light (photons) may cause changes in dna.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
