Diffusion is the movement of a substance? A. only through a lipid bilayer membrane
B. from an area of low concentration to an area of higher concentration
C. only in liquids
D. from an area of high concentration to an area of lower concentration

D.from an area of high concentration to an area of lower concentration

Explanation:

Explanation:

Diffusion also happens for gases, so it is not C. Diffusion does not require energy, so it is not B. It cannot be A as diffusion can happen through other membranes, I think? Therefore, it is D.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
