The snakes living in deserts are mainly

Options

A. Ammonotelic
B. Aminotelic
C. Ureotelic
D. Uricotelic

Answer

To solve the question regarding the type of nitrogenous waste excreted by snakes living in deserts, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: The question specifies "snakes living in deserts." Snakes are classified as reptiles.

2. **Understand Nitrogenous Waste Excretion**: Different organisms excrete nitrogenous waste in various forms, primarily ammonia, urea, and uric acid. The method of excretion is often adapted to the organism's habitat and water availability.

3. **Consider the Habitat**: Desert environments are characterized by limited water availability. Organisms in such habitats tend to conserve water.

4. **Identify the Excretion Method in Reptiles**: Reptiles, including snakes, primarily excrete nitrogenous waste in the form of uric acid. This is an adaptation that allows them to conserve water, as uric acid is less toxic and requires less water for excretion compared to ammonia or urea.

5. **Define the Terms**:
- **Aminotelic**: Excretes ammonia.
- **Ureotelic**: Excretes urea.
- **Uricotelic**: Excretes uric acid.

6. **Select the Correct Answer**: Since snakes (reptiles) excrete nitrogenous waste mainly in the form of uric acid, the correct answer is **uricotelic**.

### Final Answer:
The snakes living in deserts are mainly **uricotelic**.
