Homework Answers
A. Gain electrolytes across the skin and gills.
( Due to higher osmotic concentration inside the body of fresh water fish,. the produce excess urine in kidney. By which electrolytes also loosed in urine. To compensate this special gills cell continually taking up the electrolytes from the environment.)
