Answer:
1) b) hypotonic
2) a) hypertonic
3) a) water
4) a) B to A
5) c) osmosis
Explanation:
We have two compartments with water (A) and a solution in which the solvent is water and the solute is starch (B). The solutions are separated by a semipermeable membrane, which means that only the water molecules pass through the membrane.
1) In comparison with B, compartment A has a lesser amount of solute so it is hypotonic.
2) In comparison with A, compartment B has more solute (starch) so it is hypertonic.
3) The solvent is water, which dissolves the solute (starch).
4) Only the water molecules will pass through the membrane, and the molecules always move from the compartment with a higher concentration of solute (B) to the compartment with a lesser concentration of solute (A). So, the water moves from B to A.
5) The process in which the molecules of solvent move from a more concentrated solution to a less concentrated solution through a semi-permeable membrane is called osmosis.
