31. The diagram below represents a cell in water. Formulas of molecules that can move freely across the membrane are shown. Some molecules are located inside the cell and others are in the water outside the cell. CO₂ 0₂ C₂H12O6 OCHO CO₂ CO₂ 0₂ 0₂ C₂H12O6 NH, 0₂ CO₂ 0₂ 0₂ C₂H₁₂O6 Based on the distribution of molecules, what would most likely happen to these molecules after a few hours? (1) The concentration of C6H₁2O6 will increase inside the cell. (2) The concentration of CO₂ will increase outside the cell. (3) The concentration of NH3 will increase inside the cell. (4) The concentration of O₂ will increase outside the cell.
