Question

which investigation could most likely demonstrate whether materials are getting into a cell by active transport as the cell maintains homeo- and no energy is required to maintain homeostasis. oa exposing the cell to a solution in which the material on the outside of the cell has a lower concentration of material than the insid- ob exposing the cell to a solution in which the concentration of the material outside the cell membrane is the same as the concentrat- material inside the cell, and energy is required to maintain homeostasis. oc exposing the cell to a solution in which the concentration of material outside the cell membrane is the same as the concentration c material inside the cell, and no energy is required to maintain homeostasis. od exposing the cell to a solution in which the concentration of the material on the outside of the cell has a lower concentration of ma- the inside of the cell, and energy is required to maintain homeostasis

Explanation:

Active transport moves materials against a concentration gradient (from low to high concentration) and requires energy. Option D describes a situation where the material outside the cell has a lower concentration than inside the cell (against - concentration gradient) and energy is required to maintain homeostasis, which is characteristic of active transport.

Answer:

D. 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
