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.

The question is incomplete. The complete question is:
Consider the following experiment: True-breeding tall pea plants are cut short before being pollinated to determine if there is an affect on the offspring. Which explanation for trait inheritance is this testing?
A Blended inheritance
B Gene theory
C An organism's experiences are passed to their offspring
D None of the above
Answer:
Gene theory
Explanation:
Gene theory is the proposition that genes are the basic units in which characteristics or traits are passed from one generation to another generation. Genes themselves, as derived from Mendelian theory are the basic units of heredity. The gene theory provides a basis for understanding how genes enable parents to transmit traits to next generation.
The experiment aims to discover weather the gene for tallness is still passed on to the offspring irrespective of the experience of the parents.
