Removal of metabolic waste in the form of urea is called

Options

A. Ammonotelism
B. Ureotelism
C. Uricotelism
D. Aminotelism

Answer

To solve the question "Removal of metabolic waste in the form of urea is called," we can follow these steps:

### Step 1: Understand Metabolic Waste
Metabolic waste refers to substances that are produced as byproducts of metabolic processes in the body. These substances cannot be utilized by the organism and must be excreted to maintain homeostasis.

**Hint:** Think about what happens to substances in the body that are no longer needed.

### Step 2: Identify the Forms of Nitrogenous Waste
There are different forms of nitrogenous waste that organisms can excrete:
- **Ammonia**: Highly toxic and requires a lot of water to excrete.
- **Urea**: Less toxic than ammonia and requires less water.
- **Uric Acid**: Even less toxic and requires the least amount of water.

**Hint:** Consider the toxicity of each waste product and the water requirements for excretion.

### Step 3: Analyze the Options
1. **Ammonotelism**: This refers to the excretion of ammonia and ammonium ions. This is not correct for urea.
2. **Ureotelism**: This is the process of excreting urea, which is the focus of the question.
3. **Uricotelism**: This involves the excretion of uric acid, which is also not correct for urea.
4. **Immunotelism**: This is not a recognized form of excretion.

**Hint:** Match each term with its definition to find the correct one.

### Step 4: Conclusion
Based on the analysis, the correct term for the removal of metabolic waste in the form of urea is **ureotelism**.

**Final Answer:** The removal of metabolic waste in the form of urea is called **ureotelism**.
