What happens when a resting neuron's membrane depolarizes? A)There is a net diffusion of Na⁺ out of the cell. B)The equilibrium potential for K⁺ (E_K)becomes more positive. C)The neuron's membrane voltage becomes more positive. D)The cell's inside is more negative than the outside.

When a resting neuron's membrane depolarizes, the neuron's membrane voltage becomes more positive. This occurs due to an influx of positively charged ions, such as Na+ or Ca2+, into the neuron.
