NEET 2023 Zoology Excretory System Match the Following Question

To provide a comprehensive explanation for the matching question on the excretory system in zoology, we need to understand the components of both lists (List I and List II) and how they relate to each other.

Explanation of the Correct Answer (B)

Assuming List I contains terms related to different excretory systems found in various animal groups, while List II contains the corresponding animals, we need to correctly pair them based on their physiological characteristics.

Example Pairings:

1. A - Nephridia: This is the excretory organ found in segmented worms (e.g., earthworms, phylum Annelida).
2. B - Malpighian Tubules: This is a unique excretory structure found in insects and some arachnids.
3. C - Kidneys: These are the excretory organs found in vertebrates, including mammals.
4. D - Green Glands: These are excretory structures found in crustaceans.

Given this understanding, let's analyze the correct answer (B) and see why it correctly matches the pairings:

• A-III: Nephridia (A) would match with an organism in List II that possesses this system, which could be an earthworm.
• B-II: Malpighian Tubules (B) would correctly match with insects from List II.
• C-IV: Kidneys (C) aligning with vertebrate animals in List II makes sense as mammals and birds possess kidneys for excretion.
• D-I: Green Glands (D) match with crustaceans in List II.

This option B matches all components based on the physiological structures present in the respective animal groups.

Clarification of Incorrect Options

Let's briefly explain why the other options are incorrect:

• Option A (A-I, B-II, C-IV, D-III):

  • This option incorrectly matches Nephridia with the wrong organism (I). If I does not correspond to segmented worms, the pairing is wrong.

• Option C (A-II, B-I, C-IV, D-III):

  • Here, Nephridia (A) is matched incorrectly with (II), which would not be correct if (II) is not about segmented worms. Also, Malpighian Tubules (B) are incorrectly matched with (I), which does not belong to insects.

• Option D (A-I, B-II, C-III, D-IV):

  • Similar to A, this option also presents incorrect matches. For instance, if A is matched with (I) and D with (IV), it does not follow the described physiological characteristics.

Conclusion

The correct answer is indeed B because it accurately pairs the excretory systems with their respective animal groups based on their physiological designs. Understanding the structure-function relationship in zoology is crucial for identifying these matches.

In summary, when reviewing animal physiology, always ensure to cross-reference the anatomical structures with the respective organisms to make accurate matchings.
