Final answer:

Osmosis is the transport of water through a semipermeable membrane from a region of higher concentration to a region of lower concentration, which is the opposite of the original statement. The statement is false.

Step-by-step explanation:

The statement that osmosis is the movement (diffusion) of solvent molecules through a selectively permeable (semipermeable) membrane into a region of lower solute concentration is false. Osmosis is actually the transport of water from a region of higher water concentration to a region of lower water concentration, across a semipermeable membrane. The direction of osmosis is driven by the imbalance in water concentration, which is inversely proportional to the solute concentration. This means that water moves across the membrane to the side where there are more solute particles, effectively towards the area of higher solute concentration, in an attempt to balance the solute concentrations on both sides of the membrane.

For example, when your body has a higher concentration of water compared to an environment like Epsom salt, water will move out of your body to balance the concentration levels. Similarly, in the kidneys, both osmosis and dialysis are processes that help cleanse the blood, with osmosis focusing on water transport and dialysis on other solutes.
