Question

which biomolecule provides long term storage and insulation? protein lipid carbohydrate nucleic acid

Explanation:

To determine the biomolecule for long - term storage and insulation, we analyze each option:

• Proteins are mainly for structural support, enzyme activity, etc., not long - term energy storage or insulation.
• Lipids (like fats) are known for long - term energy storage. Also, in organisms, lipids (such as fat layers) provide insulation (e.g., in mammals to retain heat).
• Carbohydrates are for short - term energy storage (e.g., glucose, glycogen for quick energy needs).
• Nucleic acids (DNA, RNA) are for storing and transmitting genetic information, not for energy storage or insulation.

Answer:

B. Lipid
