Answer 1

Answer:

(A) The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.

Explanation:

The vertebrate and many of the other parts of the skeletal structure of the gorilla and chimpanzee are alike. (and, by using a little background knowledge, you can figure this out by thinking; if humans share 98% of DNA with chimpanzees and about 96% of DNA with gorillas, then the two animals must share a lot of DNA as well.)

I hope this helps !!!

Answer 2

Answer:

1, 3, 4

Explanation:

The gorilla and the chimpanzee have very similar anatomy, so they are closely related.

There is a small resemblance between the dog and the frog, but nowhere close to the one shared with the gorilla and chimpanzee, so NO

the dog IS more closely related to the frog than the chimpanzee since it looks more similar

yes, all of them are vertebrates and therefore share a single vertebrate ancestor
