D) no charged particles.

Question

Quizplus · Accepted Answer

A neuron at rest typically contains a high concentration of positively charged sodium ions outside the cell and a high concentration of negatively charged chloride ions and protein molecules inside the cell. This creates a potential difference known as the resting membrane potential, which is around -70mV. The presence of both positive and negative ions contributes to this potential difference.
