Solution

The maintenance of a resting membrane potential is due to three factors:

(1) The concentration of K+ inside the membrane is higher than that outside the membrane. This is due to the activity of the sodium-potassium pump, which pumps K+ into the cell.

(2) The concentration of Na+ outside the membrane is higher than that inside the membrane. This is also due to the activity of the sodium-potassium pump, which pumps Na+ out of the cell.

(3) The membrane is more permeable to K+ than Na+. This means that K+ ions can pass through the membrane more easily than Na+ ions. This difference in permeability contributes to the maintenance of the resting membrane potential.
