Question

multiple choice question
functions of the cerebral hemispheres are divided, such that _.
o one hemisphere is usually dominant for certain intellectual functions
o they are equally active in most people; one does not dominate the other

Explanation:

In neuroscience (a subfield of Natural Science, specifically Biology - related to brain function), cerebral hemispheres show functional lateralization. This means one hemisphere (usually left or right) is dominant for certain intellectual functions like language (left in many) or spatial reasoning (right in many). The second option is incorrect as hemispheres aren't equally dominant for all functions; there's specialization.

Answer:

A. one hemisphere is usually dominant for certain intellectual functions
