Question

the membrane of a resting neuron is said to be
○ deconcentrated.
○ concentrated.
○ depolarized.
○ polarized.

Explanation:

A resting neuron's membrane has a voltage difference (negative inside, positive outside) due to ion distribution (more Na⁺ outside, K⁺ inside, and negative ions inside). This state is called polarized. "Deconcentrated" and "concentrated" don't describe membrane potential. Depolarized is when the membrane potential becomes less negative (e.g., during an action potential), not the resting state.

Answer:

D. polarized
