Hints & Solutions
(b) Uric acid is the chief nitrogenous component of the excretory product of cockroach. Animals which live in dry conditions have to conserve water in their bodies. Therefore, they synthesise crystals of uric acid from ammonia. Uric acid crystals are non-toxic and can be retained in the body for a considerable time. Uricotelic animals include insects, reptiles and birds.
