The heat of the sun provides energy to make the water cycle work. #1 I The sun evaporates water from the lakes, rivers, oceans into water vapor which rises up.

#2 : The heat of the sun also causes water to evaporate from plants.

#3 : The water vapor condenses into clouds as it cools in the atmosphere.

#4 : Water drops form in clouds, which then falls to Earth as precipitation like rain and snow.

#5 : Rainfall & Snow become runoff which flows into lakes, rivers, & oceans.​

explanation:

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.
