• A. Desert mouse
• B. Carnivorous bird
• C. Freshwater fish
• D. Garden bladder

Answer 1

The correct option is C Freshwater fish

The main function of loop of Henle is the reabsorption of water from the contents of renal tubules. Freshwater fish has no loop of henle. Their bodies take on water by osmosis, therefore they rid their bodies of excess water rather than conserve it. Freshwater fish drink little water and produce large amount of urine. these mechanism work to maintain their body fluids hypertonic to their freshwater surroundings. Thus, option C is correct. Desert mouse, carnivorous bird and garden bladder has loop of henle to conserve water.
