Giving brainliest need ! how does the structure of epithelial tissue it to perform its function? a. its ability to conduct electrical signals allows for control and coordination of body movements. b. its fibrous layers allow the tissue to be a strong yet flexible binding agent. c. its contractile cells that make up the tissue allow for movement. d. its tightly packed cells allow for protection against harmful substances.

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.
