Question

if a cell contains 95% water in its cytoplasm and the environment surrounding the cell contains 90% water water will flow into the cell by osmosis. water will flow out of the cell by active transport. water will flow out of the cell by osmosis. water will flow into the cell by active transport. water will flow into the cell by facilitated diffusion.

Explanation:

Osmosis is the movement of water across a semi - permeable membrane from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration). The cell has 95% water (so 5% solute) and the environment has 90% water (so 10% solute). So the water concentration is higher inside the cell. Water will move out of the cell (from higher water concentration inside to lower water concentration outside) by osmosis. Active transport requires energy and is for moving substances against concentration gradients, and facilitated diffusion is for specific molecules with the help of proteins, not water in this case.

Answer:

C. water will flow out of the cell by osmosis.
