उत्तर
In cockroaches, air enters the body through spiracles.
Explanation:
Spiracles are small, valve-like openings located along the sides of a cockroach’s body. Air enters through these holes and flows directly into an internal network of air tubes, called tracheae, to deliver oxygen directly to the cells.
