In your own words, explain how the precise timing of an element's radioactive decay helps scientists find the actual age of a material? (5 points)

Precise time can be studied with the help of amount of carbon in the body. By measuring the amount of carbon in the body scientist can find the actual age of a material

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.
