Answer 1

The correct definition of osmosis is:

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

This process occurs naturally as water moves from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration) without the use of energy.
