Answer:
Water is a polar molecule and also acts as a polar solvent. When a chemical species is said to be "polar," this means that the positive and negative electrical charges are unevenly distributed. The positive charge comes from the atomic nucleus, while the electrons supply the negative charge. It's the movement of electrons that determines polarity. Here's how it works for water
Explanation:
If the membrane only allows osmosis to take place, the cell would shrink.
Osmosis is the thermal movement of water molecule (solvents) through a selectively permeable membrane (the cell membrane) from a region of low concentration of solute to a region of high concentration of solute.
When a cell contains 50% solute and 50% solvent is means it is isotonic.
When a solution surrounding a cell contains more solute (70%) and less solvent (30%) than the cell, it is said to be hypertonic.
Therefore when an isotonic cell is placed in a hypertonic solution, there would be movement of water molecules from the cell, which has low concentration of solute to the surrounding solution with high solute concentration.
