The goosefish tends to lives on the bottom of the ocean, where oxygen levels may be significantly less than the surface of the water, where the mackerel often swims. assume that the partial pressure for oxygen is 50 mm hg where the goosefish lives, and 100 mm hg where the mackerel lives. adjust your answer to the question you answered above based on this new information – that is, how much more oxygen will cross the respiratory membrane of the mackerel compared to the goosefish? (hint – again, express an answer in how many times more gas would exchange in the mackerel gill). (3)
