BIO 100 M1 LAB ASSIGNMENT ACT II
SCIENTIFIC REASONING ACTUAL QUESTIONS
WITH VERIFIED SOLUTIONS
◉ Does the passive transport require energy?
Answer: No
◉ Does the active transport require energy?
Answer: Yes
◉ What is diffusion?
Answer: Movement across a selectively permeable membrane
following a concentration gradient
◉ What is osmosis?
Answer: spontaneous net movement of solvent molecules through a
semipermeable membrane into a region of higher solute
concentration, in the direction that tends to equalize the solute
concentrations on the two sides
◉ What is facilitated diffusion?
Answer: Diffusion via a carrier protein
