Question

a red blood cell is placed into an aqueous solution. the red blood cell has a lower concentration of protein and sugar than the aqueous solution, as shown in the diagram. in the diagram, the volume of the cell is equal to the volume outside the cell. what is most likely to occur? water from the solution will diffuse into the red blood cell protein and sugar from the red blood cell will diffuse into a solution protein and sugar from the solution will diffuse into the red blood cell water from the red blood cell will diffuse into the solution

Explanation:

Osmosis occurs when there is a concentration - gradient. The red blood cell has a lower concentration of protein and sugar (higher water concentration relatively) compared to the aqueous solution. Water will move from an area of higher water concentration (inside the cell) to an area of lower water concentration (outside the cell) through osmosis. Proteins are large molecules and do not easily diffuse across the cell membrane, and sugar concentration is higher outside the cell so it won't diffuse into the cell in this case.

Answer:

Water from the red blood cell will diffuse into the solution
