10. This tiny animal, a rotifer, "breathes" by absorbing oxygen directly through its skin and letting the gas diffuse throughout its body. The rotifer uses all the oxygen it takes in to survive. If the rotifer doubled in diameter, would it still be able to absorb enough oxygen to stay alive? ENTRE ASTERN -0.5 mm- A. Yes, because the large and small rotifers have the same chemical make-up. B. Yes, because the larger rotifer has a greater surface area through which oxygen can pass. C. No, because the larger rotifer has to supply oxygen 8 times the body mass although the surface area increases only 4 times. D. No, because the oxygen has to travel farther in the larger rotifer.
