Question 2

Question

Answer
  • True
  • False

Question 3

Question
What is Diffusion??
Answer
  • Movement of water across a selectively permeable membrane, from an area where it is at a greater concentration to an area where it is less.
  • Spreading out of particles (gases) from areas of higher concentration to areas of lower concentration along a concentration gradient.

Question 4

Question
What is Osmosis??
Answer
  • Special case of diffusion.
  • Spreading out of particles(gases) from an area of higher concentration to an area of lower concentration along a concentration gradient.
  • Movement of water through a selectively permeable membrane, from an area where it is at a greater concentration to an area where it is less.
