B)speciation
C)convergent selection
D)stabilizing selection
Answer:
B)speciation
Explanation:
Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.
An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.

Explanation:
O The water would move into the cell and the cell would increase in size.
O The salt would move into the cell and the cell would increase in size.
O The salt would move out of the cell and the cell would decrease in size..
Answer:
The water would move out of the cell and the cell would decrease in size.
Explanation:
This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.
In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size
If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell and the cell would decrease in size.
If an animal cell with an internal salt concentration of 10% is placed in a salt solution with a concentration of 30%, the water would move out of the cell due to osmosis. The higher external salt concentration draws the water out of the cell, causing the cell to shrink or decrease in size.
