Adding a drug which decreased the neuron's membrane permeability to sodium would do what to the resting potential?
A. Decrease the neuron's resting potential to a more negative value since fewer sodium ions will enter the cell.
B. Decrease the neuron's resting potential to a more negative value since fewer sodium ions will leave the cell.
C. Increase the neuron's resting potential to a less negative value since fewer sodium ions will enter the cell.
D. Increase the neuron's resting potential to a less negative value since fewer sodium ions will leave the cell.
E. Have no effect on the neuron's resting potential since it depends solely on potassium conductance.
