hey buddy here is your answer
b -that the first occurs in the mitochondria and the second occurs in the chloroplasts
explanation:
Oxidative phosphorylation occurs on the inner mitochondrial membrane and the high energy electrons originate from reduced coenzymes NADH and FADH2 (from the Krebs Cycle, Link Reaction and Glycolysis), whereas non-cyclic photophosphorylation occurs on the thylakoid membrane in the chloroplasts, and the electrons
The location that should have lowest oxygen concentration would be the tissue because it is the furthermost location.
Other location with lowest oxygen concentration should be in the right part of the heart. It is when all unoxygenated blood pooled before going to the lungs. But the left part of the heart will have highest oxygenated blood, so it's ambiguous.
High oxygen concentration should be found in the environment, lungs, and the blood.
A new substance is produced
C.
The nonnative species would not affect biodiversity because it's unlikely the species would survive.
