The correct answer is- survive and reproduce more.

Explanation:

Natural selection is a long term process in which the organism is adapted according to the environment. These organisms tend to survive and reproduce more in comparison in those who did not adapt their-selves as per the conditions.

Such an organism that adapts according to the environment shows the increase in their size as they also tend to reproduce more each generation.

Thus, the correct answer is - survive and reproduce more.

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.
