which of these is not true of a fat molecule?
a. fats provide long - term energy storage.
b. fat molecules are a complex carbohydrate.
c. fat molecules can be obtained by eating oily foods.
d. fat molecules are found in the tissues of organisms.

Explanation:

• Option A: Fats are known for long - term energy storage, so this is true.
• Option B: Fat molecules are lipids, not carbohydrates (complex or simple). Carbohydrates and lipids are distinct macromolecule types. So this statement is not true.
• Option C: Oily foods are a source of fat molecules, so this is true.
• Option D: Fat molecules are present in the tissues of organisms (e.g., adipose tissue), so this is true.

Answer:

B. Fat molecules are a complex carbohydrate.
