List three components of traditional cell theory

The generally accepted parts of modern cell theory include:

All known living things are made up of one or more cells.

All living cells arise from pre-existing cells by division.

The cell is the fundamental unit of structure and function in all living organisms.

Cells are the basic unit of structure and function for all living things.

All organisms are made of cells.

All cells come from preexisting 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.
