Question

4 what is osmosis? multiple choice the movement of water across a semipermeable membrane the active transport of water across a semipermeable membrane endocytosis of water the net movement of water from an area of low water concentration to an area of high water concentration

Explanation:

Osmosis is the passive movement of water molecules across a semi - permeable membrane from an area of high water concentration to an area of low water concentration. It is a type of diffusion and does not require energy input (unlike active transport). Endocytosis is a different cellular process involving the engulfing of substances into the cell.

Answer:

the movement of water across a semipermeable membrane
