Question

Which one is odd one out on the basis of respiration:
Amoeba, cockroach, earthworm, euglena

Answer 1

Cockroach is you answer.

Step-by-step explanation:

They do this by using a very efficient breathing system that uses air filled tubes, called trachea, to deliver oxygen directly to cells. Oxygen flows in as required into the tracheal system through valves on the insect, called spiracles. But, sometimes, they shut their spiracles and stop breathing.
