In the light reactions, electrons from replenish chlorophyll molecules that have given up electrons.

 The light reactions of noncyclic photophosphorylation takes place in the chloroplast. The light energy is converted to chemical energy to produce both ATP and NADPH, which act as energy-transfer molecules in the light-independent reactions of the Calvin cycle. The addition of phosphate due to synthesizing of ATP by cells results to photophosphorylation.

Moreover, the electrons from water replenish chlorophyll molecules that have given up electrons by photolysis. The two electrons from the water molecule are kept in photosystem II, while the 2H+ and 1/2O2 are left out for further use.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
