Kidneys
Explanation:
ADH is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced.
The key evolutionary development of animals seen for the first time in sponges is that of Multicellularity. A Multicellular organism has a longer lifespan than an unicellular organism and since it has multiple cells, it can perform more functions. Sponges do not have distinct circulatory, respiratory, digestive, and excretory systems – instead the water flow system supports all these functions.
