The term _______________ describes the movement of molecules across a membrane down a pressure gradient from an area of higher pressure to and area of lower pressure normally resulting from hydrostatic forces

a. Filtration
b. Carrier-mediated diffusion
c. Active transport
d. Osmosis

a
Rationale: a. Filtration is correct.
b. Carrier-mediated diffusion occurs when a protein is involved in binding and causing change in membrane shape to allow diffusion.
c. Active transport involves the use of energy to cause diffusion.
d. Osmosis is the movement of water from an area of low solute concentration to an area of high solute concentration.
