Na: positive; OH: negative
<h2>Answer:</h2>
The correct answer is option A which is, "Electrons are re-energized to be used in NADPH production".
<h3>Explanation:</h3>
In photosystem II, light energy is used to split water molecules which release electrons.
These electrons then move to photosystem I to reduce NADP to NADPH.
Hence electrons in photosystem II are ultimately used to produce NADPH and option C is the correct statement.
For purposes of making a prediction, the underlying reason for a correlation does not matter. As long as the correlation is stable–lasting into the future–one can use it to make predictions. What a correlation does not tell you is why two things tend to go together.
I think the correct term would be carbon dioxide. When a person removes co2 from the lungs by exhaling, the person also removes carbon dioxide from the blood. As the blood flows in the lungs, carbon dioxide would pass out from the blood and by diffusion to the alveoli. Then, by exhaling it is removed from the the lungs.
