Question

which type of passive transport involves the movement of small molecules across the cell membrane, not specifically referring to the movement of water, from areas of high concentration to areas of low concentration? enter the answer

Explanation:

Passive transport has types like diffusion, osmosis (water movement), and facilitated diffusion. The question asks for passive transport of small non - water molecules from high to low concentration. Diffusion (simple diffusion) is the movement of small, non - polar or small polar molecules across the cell membrane down the concentration gradient without the need for energy, and it's not specifically about water (osmosis is for water). Facilitated diffusion needs transport proteins, but the question doesn't mention that. So the answer is simple diffusion (or just diffusion as the key type here).

Answer:

Simple diffusion (or Diffusion)
