C. negatively charged
D. hydrophilic
E. a sugar


Sagot :

Final answer:

Hydrophobic molecules can freely diffuse through a phospholipid bilayer, while hydrophilic or charged molecules face difficulty. Examples of molecules like potassium chloride and fructose are less likely to diffuse through due to their properties.


Explanation:

Hydrophobic molecules can diffuse freely through a phospholipid bilayer. Large polar or ionic molecules, which are hydrophilic or charged, cannot easily pass through. For example, potassium chloride and fructose are less likely to diffuse through the membrane due to their properties.
