True step one is making observations
Too bad there's not the options, but the answer must be the hydroxyl and carbonyl group.
The solubility of sucrose in water as well as organic solvents is very high. In non-aqueous solvents is generally lower. On the other hand, sucrose is not soluble in nonpolar solvents. This solubility in the polar solvent as well as the water is due to the hydroxyl (-OH) and carbonyl (-C = O) functions creating hydrogen bonds with the solvent molecules making it easier to dissolve.

C. A gene is a segment of a DNA strand
Explanation:
Just took test
Answer:
Used as the primary source of energy in living organisms
Explanation:
Proteins are the main structural and functional molecules of the body. They make up hormones that are used in signaling, make up the structure of cells, immunoglobulins, carrier proteins, and etcetera. However, the main energy source of the cells is glucose (sourced from carbohydrates). Protein is metabolized as the last resort after glucose and fats. This is because protein breakdown has toxic nitrogenous byproducts (such as creatinine, ammonia, and urea) due to their amino group.
