Metanephridia is excretory organ of:
Correct answer: D. None
- A. Planaria
- B. Hydra
- C. Cockroach
- D. None
Explanation
The correct answer is 'None'. Metanephridia are a type of excretory and osmoregulatory system found in certain invertebrates, particularly annelids like earthworms. Planaria have protonephridia, hydra lack specialized excretory organs, and cockroaches rely on Malpighian tubules for excretion. Therefore, none of the options listed possess metanephridia as their excretory organ.

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.
