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.

Eva8 [605]

Answer:

The leaf discs only float in bicarbonate solution and in the light environment.

Explanation:

The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:

NaHCO3 + H2O → H2CO3 + OH- + Na+

Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen
