Answer:
either one of the two alleles in a diploid individual.
Explanation:
A trait is expressed only when two alleles pair up. Thus, an allele pair during cell division assort independently into two individual alleles so that each gamete receive one of the two allele
For example
During gamete formation XX and XY allele pairs divide to contribute one allele to each gamete respectively.
Thus, XX allele pair will divide to give X gene to both the gamete
And XY pair will divide to give X gene to one gamete and Y gene to other gamete
Answers:
1) Water
2) NADH
--------
1) Water donates the initial electron in photosynthesis. The process of photolysis splits the water into H+ and O2 (oxygen, a byproduct of photosynthesis), and releases electrons which are taken up by photosystem II.
2) The electron transport chain is in the last step of cellular respiration, oxidative phosphorylation. NADH donates the electrons, which are used to pump H+ against the gradient into the intermembrane space of the mitrochondria. These H+ flow back across the membrane through ATP synthase to generate ATP.
