Biology QUESTION 1. compared the seawater (SW) acclimation response of three salmonid species. All fish were maintained in freshwater (FW) prior to the experiment, and then were transferred directly to SW and acclimated for up to 30 days. Blood samples were collected from fish in FW and at defined intervals during SW acclimation, and then used to measure plasma osmolarity. In the plot below, points marked with an asterisk (*) indicate a significant difference from the FW control in the same species. The figure below displays results from an experiment that 450 Arctic char Atlantic salmon Rainbow trout 425 - 400 375 350- 325 300 ot FW1 2 4 10 30 Time after SW transfer (days) C) Which of the three salmonid species is more tolerant to SW and why?
