The hypothesis that the fluttering of spiracles might help in preventing the partial pressure of oxygen (PO 2 ) from reaching a toxic level is viable or not. Given: Researchers exposed pupae to a different level of atmospheric oxygen (O 2 ) to study the activities of spiracles in differing atmospheric conditions and the effects this might have on the rate of carbon dioxide (CO 2 ) release and O 2 concentrations. They then measured levels of CO 2 release and O 2 concentrations during the fluttering stage. The results are depicted in the graphs shown below: Introduction: Primary respiratory organ of insect is trachea, which branches across the body of the insect. Trachea helps in gaseous exchange that is the exchange of CO 2 and O 2 . The intake and outgoing of the gases are maintained by spiracles. The spiracles close and open the trachea or flutters according to need.
