water reacts with sodium mental to produce sodium hydroxide and hydrogen gas along with heat and light. what are the reactants in this chemical reaction?

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.

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
