- Many types of fishes live in freshwater. Generally, water moves by osmosis from the surrounding fresh water into the fish's body. This observation helps to explain which feature of the excretory systems of freshwater fishes? a. They tend to produce dilute, watery urine. b. They tend to produce concentrated, dark urine. c. They do not produce urine, but instead conserve or re-use nitrogenous wastes. d. They may produce either dilute or concentrated urine, depending on the activity of the fish.arrow_forwardDraw a labelled diagram of excretory system of "common carp" fish?arrow_forwardHow does the hormone Angiotensin II affect MAP?
