What is the primary difference between osmosis and diffusion?

• Osmosis involves the movement of solutes, while diffusion involves water

• Osmosis requires energy, while diffusion does not

• Osmosis involves the movement of water, while diffusion involves solutes

• Osmosis occurs only in plant cells, while diffusion occurs in all cells

How does a hypothesis differ from a theory in scientific terms?

• A hypothesis is a proven fact, while a theory is a guess

• A hypothesis is a tentative explanation, while a theory is well-substantiated

• A hypothesis is more complex than a theory

• A hypothesis is a law, while a theory is an observation

DOK Level 2: Skill/Concept

Evaluate the importance of the cell membrane's selective permeability.

• It allows all substances to enter the cell freely

• It prevents all substances from entering the cell

• It allows the cell to maintain homeostasis by regulating entry and exit of substances

• It has no significant role in cell function
