Answer:
The reasons are explained below -
Explanation:
The large finches living on the Galapagos islands are different from the original source population from a nearby islands because of the following reasons -
- A natural selection favored only the large finches because they are more fit to the current environmental conditions.
- A genetic drift has been occurred in the two populations living on the nearby islands.
- Due to the separation of habitat on both the islands, the gene flow between the two islands is reduced.
All the above listed reasons are responsible for the difference in the finches found on the two islands.
Fermentation enables cells to produce chemical energy from the breakdown of sugar
The statement given in the question is TRUE.
Both government and many business organization have make grand efforts to conserve and preserve natural resources and to keep the environment from been polluted. The government has enacted many laws that has to do with conservation of environment and natural resources, some of these laws have to do with how much pollutant business organizations can release into the environment. Overall, all the preservation and conservation efforts have impacted positively on the environment.
Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.
