The correct Answer is:
To solve the question regarding the structure formed by the 7th, 8th, and 9th sterna in female cockroaches, follow these steps: ### Step-by-Step Solution: 1. **Identify the Sterna**: In female cockroaches, the 7th, 8th, and 9th sterna are specific segments of the exoskeleton located in the abdominal region. 2. **Understand the Function**: The sterna serve as protective and supportive structures for the internal organs. They play a crucial role in the reproductive system of female cockroaches. 3. **Determine the Combination**: The question asks what structure is formed by the combination of the 7th sternum with the 8th and 9th sterna. 4. **Recognize the Structure**: The 7th sternum, along with the 8th and 9th sterna, forms the **genital pouch** (also referred to as the brood pouch). This pouch is essential for the reproductive processes of the female cockroach. 5. **Conclusion**: Therefore, the correct answer to the question is that the 7th sternum together with the 8th and 9th sterna forms the **genital pouch**. ### Final Answer: The 7th sternum together with the 8th and 9th sterna forms the **genital pouch** in female cockroaches. ---
