Waterproof surfaces like the cuticle of a leaf and the protective covering of an insect's body are:
Correct answer: B. Waxes
- A. Phospholipids
- B. Waxes
- C. Terpenoids
- D. Acylglycerols
Explanation
The correct answer is waxes. Waxes serve as a protective coating because they are hydrophobic, making surfaces waterproof. This property makes them ideal for the cuticles of leaves and the exoskeletons of insects, providing a barrier against water loss and environmental factors. Phospholipids, while essential for cell membranes, do not provide a waterproof coating. Terpenoids are more related to plant pigments and scents rather than waterproofing. Acylglycerols, commonly known as fats and oils, are primarily involved in energy storage rather than forming protective barriers.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
