Question

question 1

___ is the term used to describe the total solute concentration of a solution.

• osmolarity
• molarity
• absorption
• molality

question 2

which of the following is a type of active transport which involves moving larger materials out of a cell?

• simple diffusion
• endocytosis
• facilitated diffusion
• exocytosis

Explanation:

Analyze Question 1

Using the Tonicity knowledge point, we evaluate the term for total solute concentration.

• Osmolarity measures total solute concentration per liter of solution.
• Molarity measures moles of a specific solute per liter.
• Molality measures moles of solute per kilogram of solvent.
• Absorption is a physical or chemical process, not a concentration measure.

Thus, osmolarity is the correct term.

Analyze Question 2

Using the Exocytosis knowledge point, we identify bulk transport out of a cell.

• Simple diffusion and facilitated diffusion are passive transport mechanisms.
• Endocytosis is active transport that moves materials into the cell.
• Exocytosis is active transport that expels large materials out of the cell.

Thus, exocytosis is the correct choice.

Answer:

Question 1

• (A) Osmolarity (Correct answer)
• (B) Molarity
• (C) Absorption
• (D) Molality

Question 2

• (A) simple diffusion
• (B) endocytosis
• (C) facilitated diffusion
• (D) exocytosis (Correct answer)
