a. Lipids will dissolve in water but not carbohydrates.
b. Carbohydrates will dissolve in water but not lipids.
c. Carbohydrates contain hydrogen, carbon, and oxygen and lipids do not.
d. Lipids contain hydrogen, carbon, and oxygen and carbohydrates do not.

Answer 1

Lots of differences, but here's one: Carbohydrates are more rapidly transformed by the body into energy than lipids are. As a result, carbohydrates have a more pronounced impact on insulin levels than lipids do.

Answer 2

B. Carbohydrates will dissolve in water but not lipids

Step-by-step explanation:

Both carbohydrates and lipids have oxygen, carbon and hydrogen molecules in their compositions.

However, the difference is that carbohydrates are polar and lipids are nonpolar. Nonpolar substances can only be dissolved in nonpolar solvents and so they are insoluble in water (which is polar). Compounds with this feature are called hydrophobic.
