InterviewSolution

1.	Assertion : Insects develop a complex system of air tubes called trachea for respiratory purpose. Reason : Exchange through body surface is not possible in insects.
Answer» Correct Answer - a As the integument of insect is thick and impermeable ot minimize lose of body water , they can not carryout gas exchange though their body surface. To overcone this difficulty they have developed a complex system of air tubes called trachea to reach the air direclty near the tissue cells. Each trachea communicates with the exterior through openings in the body wall.
