How does the structure of the cell membrane help the cell regulate water?

• It repels water from the cell membrane

• It controls the movement of water into and out of the cell

• It allows water to freely enter and exit the cell

• It prevents water from entering the cell

Is this an atom or a molecule? (Refer to the diagram)

• Atom

• Protein

• Molecule

• Cell

The red spheres represent oxygen atoms, and the blue spheres represent hydrogen atoms. Is this substance a compound? (Refer to the diagram)

• Yes, because it contains different types of atoms

• No, because it only contains one type of atom

• Yes, because it is a mixture of elements

• No, because it is a pure substance
