Why do some vegetables lose water when salt is applied to them?
Correct answer: B. Due to the more negative water potential of the external environment that the cell
- A. Due to the less negative water potential of the external environment than the cell.
- B. Due to the more negative water potential of the external environment that the cell
- C. Due to the less positive water potential of the external environment than the cell
- D. Due to more positive water potential of the external environment than the cell
Explanation
Water potential becomes more negative with solutes (salt) (less negative with purity). When salt is applied to the vegetable the osmotic (water) potential of the external surface of vegetables becomes more negative as a result of which water moves down the water potential gradient out of the cell, making them lose water.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
