• They are not exposed to enough sunlight.

• Salt lowers the freezing point of water.

• Salt affects the osmosis process in plants.

• They dislike cold weather.

In osmosis, water moves from an area of high concentration to an area of:

• High solute concentration

• Low solute concentration

• Equal solute concentration

• No solute concentration

What happens to the water level on side B of the U-tube when salt is added?

• It remains the same

Why is pure water not used in IV fluids?

• It is not sterile

• It is too heavy

• It can cause red blood cells to burst

• It is too expensive

How do root hair cells absorb water from the soil?

• By active transport
