Question

osmosis moves water from a region of ____ to a region of ____. low concentration of dissolved material; high concentration of dissolved material high concentration of dissolved material; low concentration of dissolved material low concentration of water; high concentration of water hypertonic solution; hypotonic solution

Explanation:

Osmosis is the passive movement of water across a semipermeable membrane. Water moves down its concentration gradient, which means it travels from an area where dissolved solute (dissolved material) is low (so water concentration is high) to an area where dissolved solute is high (so water concentration is low). A hypertonic solution has high solute concentration, hypotonic has low, so water moves from hypotonic to hypertonic, which eliminates the last option. The correct pair matches the direction of water movement relative to dissolved material concentration.

Answer:

low concentration of dissolved material; high concentration of dissolved material
