A) the intracellular concentration of potassium ions will increase.
B) the neuron will slowly depolarize.
C) the membrane will slowly lose its capacity to generate action potentials.
D) the inside of the membrane will have a resting membrane potential that is more positive than normal.

B) diffusion of sodium ions into the cell
C) membrane permeability for sodium ions greater than potassium ions
D) membrane permeability for potassium ions greater than sodium ions
E) The interior of the plasma membrane has an excess of negative charges.
