Students studying the workings of the kidneys completed an investigation. The students prepared four model cells by using dialysis tubing containing the same solution of blue dye and water. Each of the model cells originally had a mass of 10 grams. The students then placed each model cell in a beaker containing different concentrations of dye in water. After 24 hours, they recorded the mass of the model cells. Their data appears in the table.
Concentration of Water % Mass of Model Cell (g)
100 12
90 11
80 10
70 9
What is the most likely reason that the model cell placed in 100% water increased in mass?
Water reacted with chemicals in the model cell.
All of the water of the model cell evaporated.
Only half of the water entered the model cell.
Water diffused from the beaker into the model cell.
