Vedclass · Answer

(A) In cockroach,respiration occurs through a system of air tubes called tracheae.Inspiration (intake of air) in cockroaches is primarily a passive process.When the abdominal muscles relax,the abdominal cavity expands.This expansion creates space for the tracheal trunks to expand,which reduces the internal pressure within the tracheal system.Due to this pressure gradient,atmospheric air rushes into the tracheae through the spiracles.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: In cockroach,inspiration is a passive process.
$R$: Expansion of abdominal cavity allows the space for expansion of the tracheal trunk,as a result,air enters through the spiracle.
