Why do a chicken embryo and a cow embryo look very similar even though the adults do not? They are not related, but still have similar development. They are distantly related, so their development is similar. The embryos mutate in utero to form different structures. The genetic makeup of the two species changes during development.

The correct answer is 2nd statement.

Explanation:

Both the chicken embryo and the embryo of a cow look quiet identical as they both are distantly associated, and thus, it can be concluded that their development would be identical. The development of both the cow and chicken at the beginning similarly takes place. The resemblance in the development of both the embryos is the same because of the similarity of both ancestors.  

This suggests that both the chicken and cow have originated from a similar organism, and then afterward got diverged into distinct species. It has been found that the organism that exhibits the same kind of embryonic development demonstrates similar ancestry.  

The second option or answer letter B

Explanation

I just took the test on E2020 and it was correct

hope this helps :)

its temperature is increasing. this causes molecular vibrations to increase.

japan is the correct anwser because i already took the test and i passed it
