Answer:
Biogeographic isolation causes changes in gene pools that result from populations being separated.
Explanation:
Biogeographical isolation consists in the separation of a population by a geographical barrier, giving rise to <u>subpopulations</u>.
With isolation, the subpopulations start to suffer different pressures from the environment and consequently the selected genes in one subpopulation will be different from the other subpopulation.
Due to the biogeographic isolation, the two subpopulations will be prevented from crossing and the differences between them will become more and more accentuated, and with that the <u>subspecies</u> appear.
Over time, these subspecies may become so different from each other that reproduction between them becomes impossible.
When this happens, reproductive isolation occurs and, consequently, the emergence of new species. When speciation occurs due to geographic isolation, it is called allopatric speciation.
Answer: Mitochondria
Explanation: mitochondria convert food energy to power the cells
Answer:
Survival of the fittest is where the most adapted or best well suited animal will survive and thrive.
Explanation:
The correct answer among the options given is the last option. Fossil fuels are the resources that cannot be renewed. Resources that cannot be renewed or replenished are referred as non-renewable resources. Fossil fuels are made for very long periods of time and cannot be replenished instantly.
