Explanation:
Parrotfish spend 90% of their day cleaning the reef of algae. This cleaning (eating) helps corals grow and thrive, and healthy reefs support more fish in the sea. ... They snack on the hard parts of coral which becomes a white sandy material in their stomachs that they leave behind on the reef.
Since Science is all about experiment and reasoning, ' Which kind of milk tastes the best?' and ' Is it ethical to raise cows to produce milk?' - these two questions cannot be answered through science.
<h3>What Is Science?</h3>
- Science is a methodical endeavor that creates and arranges knowledge in the form of universe-related explanations and predictions that can be put to the test. Some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old, and science may be as old as the human species.
- Society values science because it may be used to better living conditions and meet a wide range of fundamental human needs. Just two current examples include the search for a cancer cure and a clean source of energy.

Answer:
If the original finches that had been blown over to the Galápagos from South America had already been genetically different from the parental population of South American finches, even before adapting to the Galápagos, this would have been an example of
E) both the first and third of these.
Explanation:
Genetic drift was the process of changing of allele frequencies over generations in a random fashion.
Founder effect is closely linked with the genetic drift. In this case, a few individuals of the original population start a new colony isolated from the other members of the species.
A founder effect happens when a new colony started from few members of the original population. The small size of population means that the colony may have a small variation of the genes in the original population.
A founder effect event happens when a small group of individuals was separated from the rest of the population, whereas a bottleneck effect occurs when most of the population is destroyed.
In the human body the nervous system function is deleting and responding to stimuli.
