Photosynthesis makes oxygen but cellular respiration takes that oxygen so how is there oxygen in the air?

Explanation:

in day time photo in photosynthesis make Oxygen and that oxygen is used by cellular respiration which produces which releases carbon dioxide in written in return so it is Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (. The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.

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.
