Answer:
- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.
- The solutions are hypotonic to the solution in the potato cells.
Explanation:
According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.
Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
I believe that hair and limbs are homology because all mammals have hair and similar limb structure. Hair loss and social behavior on the other hand are homolasy because not all mammals have them. Homology is the similar traits due to common ancestry while homoplasy is similar traits for other reasons other than common ancestry.
