- Many, but not all, marine fishes are simultaneously both osmoregulators and ionoregulators. Say that a friend caught a fish off of the Cape Cod coast where the seawater has an osmotic pressure of 1,050 mosmol.L-1 and a Na+ concentration of 450 mmol.L-1. Which of the following plasma compositions might reasonably be consistent with your friend's fish being such an osmoregulating and ionoregulating species? A. plasma osmotic pressure = 350 mosmol.L-1; plasma Na+ concentration = 430 mmol.L-1 B. plasma osmotic pressure = 1,050 mosmol.L-1; plasma Na+ concentration = 450 mmol.L-1 C. plasma osmotic pressure = 1,035 mosmol.L-1; plasma Na+ concentration = 170 mmol.L-1 D. plasma osmotic pressure = 355 mosmol.L-1; plasma Na+ concentration = 161 mmol.L-1 E. None of the above answer choices correctly answers the question.The concentration of O2 in the atmosphere declines with increasingelevation. Why do you think the times of endurance events at the1968 Olympics, held in Mexico City (elevation: 2200 m), wererelatively slow?How does the countercurrent exchange system increase the efficiency of gas exchange between a fish’s gills and blood?
