Question

the inside of a neuron is composed of ___ charged ions when at rest.
multiple choice
negatively
unambiguously
neutrally
positively

Explanation:

In a resting neuron, the inside has a negative charge due to ion distribution (e.g., more $K^+$ inside but also anions, and $Na^+$ outside). "Unambiguously" and "neutrally" don't fit ion charge context. "Positively" is incorrect for resting neuron interior.

Answer:

A. negatively
