The correct answer is: D.All of the above

Passive transport includes processes that move substances across the cell membrane without the use of energy (ATP). These processes rely on the natural tendency of molecules to move from areas of high concentration to areas of low concentration.

Here’s a breakdown of each option:

A.Osmosis: This is a type of passive transport specifically for water molecules. Water moves through the cell membrane (or via specialized channels called aquaporins) from an area of h...
