Waste product of Hydra is:
Correct answer: B. Ammonia
- A. Urea
- B. Ammonia
- C. Uric Acid
- D. None
Explanation
The correct answer is Ammonia. Hydra, an aquatic organism, excretes ammonia as its waste product. This is because ammonia is highly soluble in water, making it easier for aquatic animals to excrete it directly into their environment. Urea and Uric Acid are more common in terrestrial animals, as they provide ways to conserve water. The option None is incorrect because Hydra does produce waste products. Understanding the habitat and biological processes of Hydra helps in determining the type of waste they excrete.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
