If you were stranded on the ocean in a raft, what would happen if you kept drinking ocean water? a) your blood would become hypotonic b) your blood would become hypertonic c) the concentration of water in your blood would increase d) the concentration of water in your blood would decrease e) water would flow out of your body cells f) the excess water would flow into your cells

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
