Final answer:
Once osmotic equilibrium is reached, no net water flow occurs across a semipermeable membrane as the water concentration on both sides is equalized.
Step-by-step explanation:
After osmotic equilibrium is reached, no net flow of water will continue across a semipermeable membrane. This is because osmotic equilibrium means that the water concentration on both sides of the membrane has become equal, halting the osmotic flow. Osmosis is a critical biological process where water moves across a membrane to balance solute concentrations. While individual water molecules may still move through the membrane, there is no overall movement of water in any specific direction because the concentration gradient has been equalized.
