Answer:
Step-by-step explanation:
The cell will undergo osmosis when placed in the aquarium with distilled water. As the aquarium water is 100% water, and the cell has a solute concentration of 20%, water will move from the area of high concentration (aquarium water) to the area of low concentration (inside the cell). This means that the cell will gain water and swell up in size. The movement of water into the cell will continue until the solute concentration inside and outside the cell is equal.
