Ameoba is

Options

A. Ammonotelic
B. Ureotelic
C. Uricotelic
D. None of the above.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the type of nitrogenous waste excreted by Amoeba. The options provided are monotelic, ureotelic, uricotelic, and none of the above.

2. **Identifying Amoeba**: Amoeba is a unicellular organism classified under the kingdom Protista. It primarily inhabits freshwater environments.

3. **Nitrogenous Waste Excretion**: The type of nitrogenous waste an organism excretes is related to its habitat and physiology. There are three main types of nitrogenous waste:
- **Monotelic**: Organisms that excrete ammonia as their nitrogenous waste. This is typical for aquatic organisms.
- **Ureotelic**: Organisms that excrete urea. This is common in mammals, including humans.
- **Uricotelic**: Organisms that excrete uric acid. This is typical for reptiles and birds.

4. **Analyzing Amoeba's Habitat**: Since Amoeba is found in aquatic environments, it has access to a large amount of water. This allows it to excrete ammonia, which is highly toxic but can be diluted in water.

5. **Conclusion**: Given that Amoeba excretes ammonia due to its aquatic habitat, it is classified as **monotelic**. Therefore, the correct answer to the question is **A) monotelic**.
