What is the function of the exoskeleton in insects?
- Acts as external armour, provides space for muscle attachment, and prevents water loss (correct)
- Serves as a sensory organ, aids in camouflage, and supports locomotion
- Promotes digestion, facilitates respiration, and enables temperature regulation
- Aids in flight, stores excess water, and enhances reproduction
How do insects minimize water loss from their body surface?
How do insects minimize water loss from their body surface?
- By increasing metabolic water production, promoting evaporation, and opening spiracles
- By increasing body surface area, reducing wax production, and opening spiracles
- By using lipids and polyphenols for waterproofing, developing a wax layer, and closing spiracles (correct)
- By reducing lipid production, increasing spiracle size, and promoting water loss through the skin
