Answer:
Chlorplast plays a major role in photosynthesis. It can’t be all organisms since we humans don’t have chlorplast. Some aquatic organsisms uses chlorplast but not all, so the best answer here is A, Photosynthetc organsims.
Answer:
c. A single enzyme typically reacts with many different substrates.
Explanation:
Enzymes are proteins that have catalytic activity and they are specific. This means that a single enzyme has only one specific substrate. They act as a "lock and key" complex, so one substrate activates to one enzyme.
Also, enzymes accelerate the rate of a reaction by lowering its activation energy. Finally, they can act in an aqueous environment, so the answer is c.
<h3><u>Answer;</u></h3>
C. Energy is transferred from organisms in one level to those in the level above.
<h3><u>Explanation;</u></h3>
- Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
- As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
