Which statement is supported by the diagram?
Homo neanderthalensis is an ancestor of Homo sapiens.
Homo erectus is an ancestor of Homo sapiens.
Some ancestors can be on several branches in the hominids.
Some ancestors of Homo sapiens have not yet been identified.

The diagram shows that Some ancestors of Homo sapiens have not yet been identified.

Explanation:

The diagram (see in the picture) shows a common ancestor gave rise to Homo erectus, H. neanderthalis and H.sapiens, the first two hominids, but with evolutionary lines different from H. sapiens. At present it is not known with certainty which were the ancestors of the first individuals of the genus Homo.

The oldest evidence of the presence of H. sapiens places it in Africa (Ethiopia) about 200 years ago, and that it could have been a descendant of the H. heidelbergensis species, which migrated to Africa shortly before becoming extinct. However, the ancestors of today's man have not been clearly identified.

Biological evidence, such as the mitochondrial genome, suggests that there is no evolutionary relationship between H. neanderthalis, H. erectus and H. sapiens, which does not rule out the existence of a common ancestor that originated all three species.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
