Which investigation could MOST LIKELY demonstrate whether materials are getting into a cell by active transport as the cell maintains homeostasis? A Exposing the cell to a solution in which the concentration of the material on the outside of the cell has a lower concentration of material than the inside of the cell, and energy is required to maintain homeostasis B Exposing the cell to a solution in which the concentration of the material outside the cell membrane is the same as the concentration of the material inside the cell, and energy is required to maintain homeostasis C Exposing the cell to a solution in which the concentration of material outside the cell membrane is the same as the concentration of the material inside the cell, and no energy is required to maintain homeostasis D Exposing the cell to a solution in which the material on the outside of the cell has a lower concentration of material than the inside of the cell, and no energy is required to maintain homeostasis
