A sugar cube has completely dissolved in a glass of warm water. What can be said about the solution?

• There are an equal number of sugar molecules and water molecules.

• The concentration of sugar is the same throughout, meaning it has reached equilibrium.

• Sugar and water molecules stop moving.

• Diffusion has stopped, and active transport has begun.

• isotonic

• hypertonic

• hypotonic

• retrotonic

What do the processes of exocytosis and endocytosis have in common?

• They are a way to move materials out of a cell.

• They are a way to move materials into a cell.

• They use energy to move materials into or out of the nucleus.

• The cell membrane uses energy to surround materials that need to be transported in or out of the cell.

Cells take in different nutrients that are molecules of varying sizes. How might cells take in molecules that are too large?

• passive transport

• active transport

• diffusion

• osmosis
