directions. Does the model indicate that the molecules are moving in equal amounts in both
directions? Justify your answer using complete sentences.

Answer 1

Based on the information given in the statement, the model suggests that molecules tend to move across the membrane in both directions. However, the model does not indicate that molecules are moving in equal amounts in both directions. The random movement of particles implies that molecules may move in various directions and at different rates. Therefore, while molecules may be moving across the membrane in both directions, the quantities and rates of movement may differ, and they do not necessarily indicate equal amounts moving in each direction.
