Final answer:
A phospholipid molecule is considered 3) amphipathic because it contains both hydrophilic (water-loving) and hydrophobic (water-hating) parts.
Step-by-step explanation:
The term applied to a molecule such as a phospholipid that has distinct regions that are 'water-loving' and 'water-hating' is amphipathic. A single phospholipid molecule consists of a polar 'head' that is hydrophilic, meaning it is attracted to water, and two nonpolar 'tail' chains of fatty acids that are hydrophobic, meaning they repel and are repelled by water. Phospholipids are a prime example of amphipathic molecules, as they contain both hydrophilic and hydrophobic regions within the same molecule.
