• A) Venus' surface is 4 billion years old and has not been affected by flooding or slow evolution.
• B) Venus' surface is made of rocks that are much harder than Earth's and thus last longer.

Definitions:

White Matter

Nervous tissue in the brain and spinal cord that contains myelinated axons. Compare with gray matter.

Myelinated Axons

Myelinated Axons are nerve fibers covered by a myelin sheath, which insulates the axon and increases the speed of nerve impulse transmission, crucial for efficient functioning of the nervous system.

Unmyelinated Axons

Unmyelinated Axons are nerve fibers that lack a myelin sheath, resulting in slower transmission of nerve impulses compared to myelinated axons, commonly found in the autonomic nervous system.

Body Temperature

The measure of the body's ability to generate and get rid of heat, critical for maintaining metabolic processes in homeothermic species.
