Sudorific glands are characteristic feature of

Options

A. Birds
B. Mammals
C. Poisonous snakes
D. Toads.

Answer

**Step-by-Step Solution:**

1. **Understanding Sudorific Glands**: Sudorific glands, also known as sweat glands, are specialized structures in the skin that produce sweat. This process is important for thermoregulation (regulating body temperature) and excretion of certain waste products.

2. **Identifying the Organisms**: The question lists four groups of organisms: birds, mammals, poisonous snakes, and toads. We need to determine which of these groups possesses sudorific glands.

3. **Analyzing Each Group**:
- **Birds**: Birds do not have sudorific glands. They primarily regulate their body temperature through other means, such as behavior and feather insulation.
- **Poisonous Snakes**: Snakes, including poisonous ones, do not have sudorific glands. They rely on behavioral adaptations and environmental factors to regulate their body temperature.
- **Toads**: Toads, which are amphibians, also lack sudorific glands. They have different mechanisms for temperature regulation and moisture retention.
- **Mammals**: Mammals are the only group among the listed organisms that possess sudorific glands. These glands play a crucial role in thermoregulation through the process of sweating.

4. **Conclusion**: Based on the analysis, sudorific glands are a characteristic feature of mammals. Therefore, the correct answer to the question is "mammals."

**Final Answer**: Sudorific glands are a characteristic feature of mammals.
