What is a solute in a solution?

• The liquid that dissolves another substance

• The substance that is dissolved

• A gas that forms bubbles in water

• A solid that remains undissolved

Which of the following is an example of a solvent?

• Sugar in tea

• Salt in water

• Water in saltwater

• Oxygen in air

A solution is a mixture where

• The solute and solvent are evenly distributed

• The solute settles at the bottom

• The solvent and solute separate over time

• The substances react to form a new compound

Which of the following is NOT a characteristic of a solution?

• It is a homogeneous mixture

• The solute and solvent are evenly distributed

• The solute can be separated easily by filtration

• The solute is dissolved in the solvent

A hypotonic solution has

• A higher solute concentration than the cell

• A lower solute concentration than the cell

• The same solute concentration as the cell

• No effect on cells

A hypotonic solution will cause a cell to

• Lose water and shrink

• Gain water and swell

• Stay the same size

• Absorb solutes but not water

Diffusion is the movement of molecules

• From lower to higher concentration

• From higher to lower concentration

• Against the concentration gradient

• In a fixed position

Which of the following is an example of diffusion?

• Sugar dissolving in tea

• Oxygen moving from the lungs into the blood

• Saltwater evaporating

• Water freezing into ice

If a red blood cell is placed in pure water, what will happen

• It will shrink due to osmosis

• It will stay the same

• It will swell and possibly burst

• The solute concentration will increase

A person drinks seawater, which is a hypertonic solution. What happens to their cells

• Water enters the cells, making them swell

• Water leaves the cells, making them shrink

• The cells remain unchanged

• The cells gain solute but no water
