Convergent evolution is the development of similar traits in species that are not closely related.

#13

13. What type of rocks are formed from the accumulation of organic remains, such as shells and coral?

Sedimentary

Explanation

Sedimentary rocks form from the accumulation of organic remains, like shells and coral.
