Which of the following pairs is wrong ?

Options

A. Uricotelic`"________"` Birds
B. Ureotelic`"________"` Insects
C. Ammonotelic `"________"` Tadpole
D. Ureotelic `"______"` Elephant

Answer

To determine which of the following pairs is wrong, we need to analyze the terms and their corresponding nitrogenous waste excretion methods.

1. **Understanding the Terms:**
- **Eurycotallic:** Refers to animals that excrete uric acid as their primary nitrogenous waste.
- **Euryotallic:** Refers to animals that excrete urea as their primary nitrogenous waste.
- **Ammonotallic:** Refers to animals that excrete ammonia as their primary nitrogenous waste.

2. **Analyzing Each Pair:**
- **Eurycotallic birds:** Birds primarily excrete uric acid, so this pair is correct.
- **Euryotallic insects:** Insects primarily excrete uric acid, so this pair is incorrect because insects are not classified as Euryotallic; they are Eurycotallic.
- **Ammonotallic tadpole:** Tadpoles excrete ammonia, which makes this pair correct.
- **Euryotallic elephant:** Elephants excrete urea, so this pair is also correct.

3. **Identifying the Wrong Pair:**
- The only incorrect pair is **Euryotallic insects** since insects are Eurycotallic, not Euryotallic.

**Final Answer:**
The wrong pair is **Euryotallic insects**.
