Scientists discovered a new species of freshwater fish that lives in a pond with a very low o2 level. when they measured the oxygen extraction efficiency of the fish, it was twice as high as that of closely-related fresh water fish. answer the following questions.

a. propose a hypothesis to explain how the fish achieve a high o2 extraction efficiency.

b. list predictions that derive from your hypothesis. be as specific as possible.

c. propose an experiment to test your predictions. be sure to describe types of measurements you will make, and what comparisons you will make (i. e., what is your control
