If you ground up a cell and put all the molecules from the cell in a test tube, would this mixture of molecules be alive? explain why or why not.

No, because if you ground up a human and put it in a test tube, it would be dead but still have the same molecules

Explanation:

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.
