Camel is different from other mammals in having

Options

A. Subcutaneous fat
B. No sweat glands
C. More than seven cervical
D. Oval shaped R.B.C vertebrae

Answer

**Step-by-Step Solution:**

1. **Understanding Camel's Unique Adaptations**: Camels are known for their unique adaptations that allow them to survive in harsh desert environments. One of the most significant adaptations is related to their blood.

2. **Identifying the Options**: The question presents several options regarding what makes camels different from other mammals:
- Subcutaneous fats
- No sweat glands
- More than 7 cervical vertebrae
- Oval-shaped red blood cells (RBCs)

3. **Evaluating Each Option**:
- **Subcutaneous Fats**: While camels do have subcutaneous fat, this is not a unique feature as many mammals have it, especially those in cold climates.
- **No Sweat Glands**: This is not entirely accurate. Most mammals have sweat glands, but camels have adapted to sweat less to conserve water.
- **More than 7 Cervical Vertebrae**: Most mammals, including camels, have seven cervical vertebrae. The exception is the Bradypus (sloth), which has more.
- **Oval-shaped RBCs**: Camels have oval-shaped red blood cells, which is a unique adaptation that helps them manage dehydration effectively. This shape allows their blood to flow more easily and helps them retain water.

4. **Conclusion**: The correct answer to the question of how camels differ from other mammals is that they have oval-shaped red blood cells. This adaptation is crucial for their survival in arid environments.

**Final Answer**: Camels are different from other mammals in having oval-shaped red blood cells (RBCs).
