Question

if two organisms are in the same clade, what can you predict about their relationship?
one organism evolved into the other organism. they are not closely related. they share a common ancestor.
they compete for resources.

Explanation:

A clade is a group of organisms that includes an ancestor and all of its descendants. So, if two organisms are in the same clade, they must share a common ancestor. The statement "One organism evolved into the other organism" is incorrect as a clade is about shared ancestry, not direct evolution from one to the other. "They are not closely related" is wrong because being in the same clade implies a close evolutionary relationship. "They compete for resources" is not a prediction based on being in the same clade; competition for resources is more about ecological niche and availability of resources rather than clade membership.

Answer:

They share a common ancestor.
