Biogeographic isolation means that a population is separated and there are two populations in two different areas. As normal mutations take place, but certain mutations will be seen as advantageous in the different areas. For. Example if an area had taller trees the organism may develop a gene to grow taller. This is then passed down to offspring. This process continues so that more gene differences are created within the species and the frequency of these alleles increased: leading to two different species developing-
Answer:
The correct answer is option D which is release of water from the vacuoles.
Explanation:
The difference in second plant from the first one is rigidity. Second one is wilted and not rigid. This is due to the release of water from the vacuoles in the cell of plants.
Vacuoles are present in the center of plant cell. They are usually filled with water and provide structural support to the cell.
In the absence of water filled vacuoles, plants shoots are wilted as in case of second plant.
The right answer is pluripotent
