A tea bag can model a cell. The fabric of the bag represents the cell membrane. In part of the model, materials move out of the bag and into the water. Which of the following cell processes does this best model? O A. A vacuole opens to release substances into the area outside the cell O B. Small molecules easily pass between the phospholipids in the cell membrane. O C. Substances move from an high concentration of low concentration to an area of O D. Transport proteins use energy to push large molecules across the cell membrane
