Insects are

Options

A. Ammonotelic
B. Uricotelic
C. Ureotelic
D. None above as they excrete only guanine

Answer

To answer the question "Insects are," we need to analyze the options provided and understand the type of nitrogenous waste that insects excrete.

### Step-by-Step Solution:

1. **Understanding Nitrogenous Waste**:
- Organisms excrete nitrogenous waste in different forms based on their metabolic processes. The main types are:
- **Ammonotelic**: Excrete ammonia (e.g., fish).
- **Ureotelic**: Excrete urea (e.g., mammals).
- **Uricotelic**: Excrete uric acid (e.g., birds, insects).

2. **Identifying the Correct Term for Insects**:
- Insects primarily excrete nitrogenous waste in the form of uric acid. This adaptation helps them conserve water, which is crucial for survival in various environments.

3. **Analyzing the Options**:
- **Option A**: Ammonotelic - Incorrect, as insects do not excrete ammonia.
- **Option B**: Ureotelic - Incorrect, as this refers to organisms that excrete urea.
- **Option C**: Uricotelic - Correct, as insects excrete uric acid.
- **Option D**: None above - Incorrect, since option C is correct.

4. **Conclusion**:
- Based on the analysis, the correct answer is that insects are **Uricotelic**, as they primarily excrete uric acid.

### Final Answer:
Insects are **Uricotelic** (they excrete uric acid).
