Pepsin, a digestive enzyme that works best at low pH is a good example. Pepsin begins the process of protein digestion in the very acidic environment of the stomach. During digestion, The stomach contents pass into the small intestine where the pH of pepsin rises from pH 2 to about 7.5. Pepsin goes above pH 5.5 to denature so that this enzyme will become inactive in the small intestine. From there protein digestion continues with the assistance of trypsin, an enzyme that functions well at the higher pH.

Answer:
A. Some speculate that they were blown out to the islands by a massive storm
Explanation:
The common rosefinches are thought to have arrived on the Hawaii islands between 6 and 7 million years ago. As the common rosefinches are not big birds and they can not fly over very long distances, the scientists believe that it is a massive storm that blow some individuals to the Hawaii islands. This is nothing weird, as it has been witnessed numerous times how massive storms manage to carry some smaller birds to places where they are not able to fly on their own. Once there, the birds encountered suitable conditions for living and lot of open niches in the food chain. This resulted in quick diversification of the common rosefinches, with members of the species gradually adapting to a particular niche, experiencing changes to be more competent, and creating numerous new species after some time.
