Cell mediated immunity uses what type of WBC to attack and kill the infected cells

In these instances,the Immune System uses cell-mediated immunity to destroy infected body cells.

T Cells are responsible for cell-mediated immunity,they assist with the elimination of infected body cells by releasing toxins into them and promoting apoptosis.

T Cells,are also called T Lymphocyte,type of leukocyte (White Blood Cell) that is an essential part of the immune system.

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.
