Body volume increases at QR because of ecdysis.
Body volume does not increase at PQ because of the exoskeleton
Body volume does not increase at PQ because the insect stops growing at this stage.
Body volume increases at QR because of air intake by insect.
In an insect, the process of removing an old exoskeleton and replacing it with a new larger one is known as
dialysis
haemolysis
ecdysis
hydrolysis

Adult and larvae stages in complete metamorphosis feed on different foods and have different predators. In insect metamorphosis both adults and nymphs consume the same food and have similar predators. What is the difference between complete and incomplete metamorphosis based on the information above?
Complete metamorphosis gives insects a survival advantage.
Incomplete metamorphosis gives insects a survival advantage.
Different food habits in complete metamorphosis results in a short life cycle.
Similar food habits in incomplete metamorphosis results in a short life cycle.
