Longest podomere of cockroach's leg is

Options

A. Coxa
B. femur
C. Tibia
D. Tarsus

Answer

To determine the longest podomere of a cockroach's leg, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Podomeres**: Podomeres are the segments or subunits of the cockroach's leg. Each leg of a cockroach is made up of several podomeres.

2. **Identify the Structure of the Leg**: The cockroach leg consists of several parts:
- **Coxa**: The base segment that connects the leg to the body.
- **Femur**: The segment that follows the coxa.
- **Tibia**: The segment that follows the femur.
- **Tarsus**: The segment that consists of multiple smaller segments (tarsal segments).

3. **Compare the Lengths of Podomeres**:
- The femur is shorter than the tibia.
- The tibia is longer than the femur.
- The tarsus, which has five segments, is shorter than the tibia.

4. **Conclusion**: Since the tibia is longer than both the femur and the tarsus, the longest podomere of the cockroach's leg is the **tibia**.

### Final Answer:
The longest podomere of the cockroach's leg is the **tibia**.
