Correct answer: B. Cockroach
- A. Earthworm
- B. Cockroach
- C. Frog
- D. Man
Explanation
Cockroach shows uricotelism. Excretion of uric acid is known as uricotelism and the animals which excrete uric acid are called uricotelic. Animals which live in dry conditions have to conserve water in their bodies.Therefore, they synthesize crystals of uric acid from ammonia.Uric acid crystals are nontoxic and almost insoluble in water. Hence, these can be retained in the body for a considerable time. Uricotelic animals include most insects,(e.g., cockroach),land reptiles (e.g. lizards and snakes) and birds.

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.
