How does the water move between the hydrosphere and atmosphere?

 The total amount of water found on the earth is known as the hydrosphere. Water can be found on the surface of the earth, underground, and even in air.

It can be liquid, vapor or in the form of ice. The water on earth is found in ocean, sea, wells et cetera.

The water that is present in ocean and sea evaporates due to the heat absorbed by the sunlight. The evaporated water reaches into the atmosphere.

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.
