True/False

Natural selection acts on variations of the phenotype within the population.

Definitions:

Depolarization

A reduction in the difference in voltage across a cell's plasma membrane, making it more positive inside.

Hyperpolarization

An increase in a cell's membrane potential, making it more negative, and often reducing the likelihood of producing a nerve impulse.

Repolarization

The process of restoring the resting negative charge inside a cell membrane after depolarization, crucial for the function of nerve and muscle cells.

Nervous System

The complex network of nerve cells and fibers that transmits nerve impulses between parts of the body, comprising the central and peripheral nervous systems.
