Answer:
1. A hypotonic solution has less solute and more water potential.
2. If two solutions are of the same concentration they have the same water potential and are considered isotonic.
3. A hypertonic solution has lower water potential and more solute.
Answer:
Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.
Explanation:
Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.
Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.
