Uncontrolled cellular division poses a serious risk to surrounding tissue because it-? produces toxins that kill cells
replaces the DNA in healthy cells
crowds out healthy tissue
alters the functioning of organs

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.
