Folding of the allows for its –square-foot surface area to fit into the skull.

a.

cerebral cortex . .1.5

b.

corpus callosum . . 2.5

c.

right hemisphere . . 2.5

d.

cerebrum . .1.5

the answer is a cerebral cortex . .1.5

Folding of the cerebral cortex  allows for its  1.5 square-foot surface area to fit into the skull.

Option A

Explanation:

The cerebral cortex also known as the convoluted outer layer of the cerebrum. It can be bent and folded so that its surface area remains about 1.5 sq ft which can be folded into or packed into the skull area which was discovered by Hubel and Wiesel, in 1979.

Cerebrum is the biggest portion of the brain approximately constitute 75 percent of it and by weight 85 percent and it is divided into two right hemisphere and left hemisphere of brain which ultimately forms the whole cerebrum.

explanation:

the old way of life was represented by superstition, an angry god, and absolute submission to authority. the thinkers of the age of reason ushered in a new way of thinking. this new way championed the accomplishments of humankind. individuals did not have to accept despair. science and reason could bring happiness and progress. kings did not rule by divine right. they had an obligation to their subjects. europeans pondered the implications for nearly a century. americans put them into practice first.
