Light excites the electrons in chlorophyll a molecules of photosystem 1. As these electrons move to another primary electron receptor, electrons from photosystem 2 replace them.
Therefore the answer is FROM PHOTOSYSTEM 2.

The answer is B. The first cross between the black-eyed mendelian and an orange-eyed mendelian resulted in all of them having black eyes. This means that black-eyed is the dominant trait in the species. That means if a phenotype is orange-eyed then it is homozygous recessive (bb). There will be no black-eyed since all of them are recessive.
