Question 9
Cell and Its EnvironmentFig. 2: Experiment to demonstrate osmosis
What would happen if solution Y is more concentrated than solution X in Fig. 2?
- A.The level of X would rise, Y would fall
- B.The level of X would rise, Y would rise
- C.The levels of X and Y would stay the same
- D.The level of Y would rise, X would fall
- E.The level of Y would fall, X would fall
Show the answer and explanation
Answer: D (The level of Y would rise, X would fall)
Explanation
Water moves by osmosis from the weaker solution X through the membrane into the stronger solution Y, so Y rises and X falls.
