The hypothesis was that a species from a Pacific Rim may have been the ancestor of 28 distinct species on the Hawaiian Islands. Which of these supports this hypothesis AND could be the result of observational testing?

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
