Which of the following waste products in grasshopper is not excreted and is used in other metabolic activities?
Options
- ACarbon dioxide
- BWater
- CUric acid
- DFaeces
Correct answer
B. Water
Step-by-step solution
Excretory organs of grasshopper are the Malpighian tubules and the main excretory product is uric acid. Malpighian tubules of insects such as grasshoppers not only help to excrete the waste but also function to conserve water, which is then used in other metabolic activities. In the Malpighian tubules, bicarbonates of potassium and sodium, water and uric acid are formed during the process of excretion. A large amount of water and bicarbonates of potassium and sodium are reabsorbed by the cells of Malpighian tubules
