Question

9. The human cell contains 0.9% solutes (dissolved materials. There is 99.1% water in these cells. The Pacific Ocean contains 3.56% salt. Although this seems like a silly question, how much water is in the ocean? You are cast adrift in this ocean. What would happen to your cells if you were to drink the saltwater? 10. If human cells contain 0.9% solutes what do you think is the solute concentration of the fluid around cells? Explain what would happen to the cell if this solute concentration were to increase. Explain what would happen to the cell if this solute concentration were To decrease. 11 Frnlain wwhot onponod wbon

Explanation / Answer

9) Human cells contain 0.9% solutes and 99.1% water. The Pacific ocean contains 3.56% solutes and therefore 96.44% water. Seawater is hypertonic when compared to human cells. So, if a person drinks sea water, due to osmotic movement of water across the cell membrane, the cells will lose water and shrinks in their size.

10) If human cells contain 0.9% solutes, the concentration of fluid around the cells is higher.

If the solute concentration were to increase, the cells will lose water because of osmosis. They become dehydrated and their size decreases.

If the solute concentration were to decrease, there will be movement of water molecules into the cell and therefore their size increaes.
