Answer:
D) ATP Synthase (Hopefully that was an option, I'm not sure if option D intentionally left out the P)
Explanation:
ATP synthase is responsible for synthesizing ATP through the phosphorylation of ADP. This is the result of mechanical energy being generated by the proton motive force (H+ ions moving into the matrix). The asymmetrical rod changes the affinity for ATP, ADP, and inorganic phosphates of each subunit in the F1 subunit, allowing ATP to be produced/prepped/released. In all, this enzyme is very important in the entire process of oxidative phosphorylation.
the dense connective tissue is a scar tissue. It doesn't exert forceful contraction like muscle. The muscle as a whole is still functional although the contraction will be weaker.
The muscle is still functional because the connective tissue only replaces the damaged parts of the large muscle.
Answer:
The first question is answer A. The question asks for the independent variable, meaning this variable doesn't depend on any other variable. B is the dependent variable because the life span depends on the vitamin.
The second answer is A, the control group. It cannot be the other groups because they aren't real groups. Independent and dependent are variables, not groups.
