Which of the following mechanisms for osmoregulation or nitrogen removal is correctly paired with its corresponding animal?
A) metanephridium-earthworm
B) Malpighian tubule-frog
C) kidney-insect
D) flame- bulbsnake
The correct pairing for osmoregulation or nitrogen removal mechanism with its corresponding animal is:
C) kidney-insect
The kidney is the correct organ for osmoregulation and nitrogen removal in insects. Insects have specialized organs called Malpighian tubules that serve as excretory and osmoregulatory structures. These tubules help remove nitrogenous waste and regulate water and ion balance in insects. So, the correct pairing is Malpighian tubule - insect.
Therefore, option C) kidney-insect is the correct answer.
To determine the correct answer, we need to understand the different mechanisms for osmoregulation or nitrogen removal in various animals.
A) Metanephridium is the excretory organ in earthworms, responsible for osmoregulation and nitrogen removal in these organisms. Therefore, option A is correctly paired.
B) Malpighian tubules are the excretory organs in insects, not frogs. These tubules remove nitrogenous waste and help with osmoregulation in insects. Therefore, option B is incorrect.
C) The kidney is the excretory organ responsible for osmoregulation and nitrogen removal in vertebrates, including mammals, birds, reptiles, and most fish. Insects, on the other hand, possess Malpighian tubules. Therefore, option C is incorrect.
D) Flame bulbs are specialized structures found in some species of marine worms and are not related to osmoregulation or nitrogen removal in snakes. Therefore, option D is incorrect.
Based on the explanations, option A (metanephridium-earthworm) is correctly paired.
