Question

please give me the right answer.

thanks

In many biological solutions, water is the solvent, meaning that solute molecules are dissolved in it (think of salt or sugar water). If a solute does not move across a semipermeable membrane, it is асr known an osmotically active solute. For the following examples, assume that the solute is osmotically active. In osmosis, water molecules move across the cellular membrane down the gradient (from an area of low solute/high water concentration to an area of high solute/low water concentration) in order to equalize the solute concentration on either side of the membrane. This can be confusing, so consider the following example. In which direction(s) will the majority of water molecules move. For this activity, assume that the volume inside the cell is equal to the volume in the environment (the black box). Water molecules are indicated by blue circles, solute molecules are indicated by yellow dots. O Majority of water will enter the cell Majority of water will leave the Cell OThe same amount of water that enters the cell will leave the cell

Answer 1

Answer: The same amount of water that enters the cell will leave the cell.

Explaination

Osmosis refers to movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.

As the concentration of solute is same inside and outside the cell, it will remain in equilibrium i.e., "The same amount of water that enters the cell will leave the cell".
