Answer:
<em>Geographic isolation</em>
Explanation:
Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.
The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.

<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>
