Answer: Allopatric Speciation
Explanation:
Allopatric speciation occurs when new distinct species are formed due to the separation of a specie into two separate groups. These two groups are kept away from each other.
In allopatric speciation there is no exchange of genes between the two separate groups.
Allopatric speciation can also be known as geographical speciation.
Answer:
aka Ethenone
Explanation:
Ethenone is an organic compound made out of the elements Carbon, Hydrogen, and Oxygen. It is an example of a covalent molecule. The Hydrogens are single bonded to the carbon and then the carbons and oxygen are double-bonded to each other. Additionally, because there are 2 Hydrogens and 1 Oxygen the ratio is 2:1, as stated in the question.

<span>Cells of most organisms freeze due to the fact that. Water is less dense as a solid than as a liquid. To elaborate when you quickly freeze and organism the internal portion of that organism is freezing at a much slower rate. SO the outside portion becomes rigid eventually breaking is you freeze it at a slower rate less cells will be damaged.</span>
