Question

Why would it be impossible to kill a cockroach by holding its head down underwater?

• A. Cockroaches have lived for many centuries and are tolerant to many dangers.
• B. Cockroaches can survive without oxygen for many hours.
• C. Cockroaches take in air through holes situated elsewhere away from the head.
• D. Cockroaches have no blood and respire anaerobically.

Answer 1

Answer: (C)

Cockroaches take in air through holes situated elsewhere away from the head.

Various experiments have shown that it is not possible to kill cockroaches by holding its head underwater as it can hold its breath for over 40 minutes. This is because cockroaches can breathe air in for respiration through holes situated elsewhere away from their head.

So, the correct answer is 'Cockroaches take in air through holes situated elsewhere away from the head.'.
