Answer:
b) The passive movement of a solute across a permeable membrane, diffusion is when particles move from a high concentration to a low concentration
c) As the size of an organism increases, its surface area to volume ratio decreases. This means it has relatively less surface area available for substances to diffuse through, so the rate of diffusion may not be fast enough to meet its cells requirements.
d) one way is the temperature: higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.
another way is the mass of the solute, the temperature of the environment, the solvent density, and the distance travelled.
The greater the difference in concentration, the more rapid the diffusion. The closer the distribution of the material gets to equilibrium, the slower the rate of diffusion becomes.
3a) active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
