Match the Column I with Column II
| Column I (Organisms) | Column II (Mode of Excretion) |
|---|---|
| (A) Spiders and scorpions | (I) uricotelic |
| (B) Cartilagenous fishes and many aquatic reptiles | (II) ammonotelic |
| (C) Birds and land snails | (III) ureotelic |
| (D) Bony fishes and tadpole | (IV) guanotelic |
Options:
Answer:
B
Solution:
Spiders and scorpions excrete guanine as their primary nitrogenous waste, hence they are guanotelic.
Cartilaginous fishes and many aquatic reptiles excrete urea, hence they are ureotelic.
Birds and land snails excrete uric acid to conserve water, hence they are uricotelic.
Bony fishes and tadpoles excrete ammonia, which is highly toxic and requires a large amount of water for elimination, hence they are ammonotelic.
Thus, the correct matching is A-IV, B-III, C-I, D-II.
Answer: A-IV, B-III, C-I, D-II
