Final answer:
An entity that is both hydrophobic and hydrophilic is described as amphipathic, such as phospholipids which have a hydrophilic head and hydrophobic tails.
Step-by-step explanation:
The word that describes an entity that experiences both hydrophobic and hydrophilic effects is amphipathic. Hydrophilic refers to ions or polar molecules that interact well with other polar molecules, such as water, meaning they are "water-loving". On the other end of the spectrum, hydrophobic refers to uncharged non-polar molecules that do not interact well with water, hence they are "water-fearing". An example of an amphipathic molecule is a phospholipid, which contains a polar head that is attracted to water (hydrophilic) and nonpolar fatty acid tails that repel water (hydrophobic).
