Question

The adaptation which empowers cockroaches to live without their heads for some time is -

• A. Closed circulatory system
• B. Segmented bodies
• C. Malpighian tubules
• D. Spiracles

Answer 1

The correct option is D

Spiracles

A cockroach can live for a week without its head. Due to their open circulatory system, and the fact that they breathe through little holes or spiracles in each of their body segments, they are not dependent on the mouth or head to breathe. The roach only dies because without a mouth, it can't drink water and dies of thirst. cockroaches have spiracles on their exoskeletons to allow air to enter the trachea.
