In a laboratory, scientists exposed freshwater bony fish (Prochilodus lineatus) to water high in aluminum and compared their blood osmolarity to that of fish exposed to water with normal aluminum levels (control). The scientists also measured the activity of Na+/K+-ATPase in the gills of the fish exposed to aluminum and compared it to that of the control fish. What do you suppose were their results? Explain.
