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 up a concentration gradient from low to high, using no 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

Explanation:

Osmosis is a passive - transport process. It involves the movement of water molecules across a semi - permeable membrane from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration) without the use of energy.

Answer:

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