Question

osmosis is a form of passive transport. which defines osmosis? (1 point)

the movement of water across a semipermeable membrane up a concentration gradient from low to high, using energy

the movement of water across a semipermeable membrane down a concentration gradient from high to low, using energy

the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy

the movement of water across a semipermeable membrane up a concentration gradient from low to high, using no energy

Explanation:

Osmosis is passive transport, so it uses no energy. Passive transport moves substances down their concentration gradient (from high to low concentration). Osmosis is the movement of water across a semipermeable membrane. So the correct definition is water moving down the concentration gradient (high to low) across a semipermeable membrane with no energy use.

Answer:

the movement of water across a semipermeable membrane down a concentration gradient from high to low, using no energy
