Answer:
c. a proton gradient set up across the thylakoid membrane
Explanation:
During the photosynthesis (this also occurs in cellular respiration in mitochondria), hydrogen ions (H+) move across the thylakoid membrane down their electrochemical gradient (from the area of their higher concentration to the area with hydrogen ions lower concentration). An ion gradient can be used for the production of ATP.

What is the backup energy molecule that can be rapidly converted to ATP in active skeletal muscle?
The answer would be D. Phosphocreatine, because phosphocreatine plays a major role on energetic homeostasis in both active skeletal and cardiac muscles. Phosphocreatine is basically creatine but phosphorylated, and that is why it has such a name. It has the role of turning ADP (adenosine diphosphate) into ATP (adenosine triphosphate).
Remember, ATP is the currency of life! That is what my biology teacher taught me.

Explanation:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
