In an experiment reported in the scientific literature, male cockroaches were made to run at different speeds on a miniature treadmill while their oxygen consumption was measured. in one hour the average cockroach running at 0.08km/hr consumed 0.8 ml of o₂ per gram of insect weight at 1 atm pressure and 24 °c. this same cockroach is caught by a child and placed in a 1-qt fruit jar with a tight lid. assuming the same level of continuous activity as in the research, will the cockroach consume more than 20% of the available o₂ in a 48-hr period? (air is 21 mol percent o₂)
