Explanation:

electronic virus or sickness virus?

if electronic i think 3

if sickness i also think 3

Explanation:

for electronic i think 3 because first it would most likely be the freezing/lagging then it would be weird glitches like things popping up then for the third it would be like the electronic stops working or its working by itself

for sickness i think because first it would start off with light symptoms (minor headaches, minor stomachaches, etc) then maybe you start getting sick like coughing, throwing up, sneezing a lot, + plus minor symptoms and then it would be that you would become so sick that you need to stay in bed alot, bad symptoms, can barely walk, etc.

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.
