Which of the following best explains what is causing the red blood cells in solution 1 to change size over the 5-minute period?

• Water is moving into the cell from its environment

• Water is moving out of the cell to the surrounding environment

• Water is moving in and out of the cell in equal rates

• Solutes are moving into the cell from its environment
