Final answer:
During osmosis, water molecules move from a region of higher water concentration to a region of lower water concentration to balance solute levels across a semipermeable membrane.
Step-by-step explanation:
During osmosis, individual water molecules move from an area where they are in higher concentration to an area where they are in lower concentration. This process occurs to balance the concentration of solutes on either side of a semipermeable membrane. Although water molecules move randomly due to their kinetic energy, resulting in motion in both directions, there is a net flow of water from the side with lower solute concentration (higher water concentration) to the side with higher solute concentration (lower water concentration). Osmosis is vital as it maintains water balance in cells and is utilized by the body to regulate water distribution. Therefore, the answer is 1) From a region of higher water concentration to a region of lower water concentration.
