The active site of the enzyme is bound by a substrate and probably the enzyme catalyzes a hydrolysis reaction. The poison mimics the substrate and competes with the substrate for the active site of the enzyme. The poison may bind permanently to the enzyme rendering the enzyme unavailable for other substrates. This could make a particular biochemical reaction, in which the enzyme is involved, to reduce drastically hence threatening life.

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.
