Question

what happens to a neuron as the impulse passes a section of its length? multiple choice positive ions will move outside of the nerve cell. the neuron will return to a positive charge. the neuron will return to a negative charge. the neuron will remain neutral.

Explanation:

After an action potential (impulse) passes a section of a neuron, the neuron undergoes repolarization and then returns to its resting membrane potential, which is negatively charged inside relative to outside. So the neuron returns to a negative charge.

Answer:

The neuron will return to a negative charge.
