Answer:
1. B. Sucrose.
2. D. Ph
3. D. Carbon
Explanation:
Sucrose is 1. because carbohydrates are sugars, starches and fibers found in foods.
2. is Ph because enzymes are proteins that bring about a reaction. In this case, the Ph affects the acidic levels.
For 3. the answer is carbon because carbon assists with cellular reproduction, photosynthesis, and cellular respiration. Without carbon, the cell cannot reproduce, which eventually causes it to die off.
Molecules that contain carbon are proteins, carbohydrates, nucleic acids, and lipids.
