The polar region of a phospholipid molecule is:
Correct answer: B. Hydrophilic head
- A. Hydrophobic head
- B. Hydrophilic head
- C. Hydrophilic tail
- D. Hydrophobic tail
Explanation
Phospholipids are composed of a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails. The head is polar, allowing it to interact with aqueous environments, thus making it the correct answer. The tails are made from fatty acids, which are non-polar and do not interact with water, explaining why the other options are incorrect.

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.
