A plasma membrane is composed of a phospholipid bilayer that prevents hydrophilic solutes, such as sodium ions and potassium
ions, from freely entering the cell. By contrast, most solutes that are very small, hydrophobic, or non-polar are able to cross the
plasma membrane under appropriate conditions. Which statement best describes a condition that would enable a hydrophobic
solute to enter the cell?
