What are the functions of rigid arthropod exoskeleton? - CORRECT ANSWER-Support,
protection, and contributes to efficient locomotion
Specialized gas exchange found in aquatic species - CORRECT ANSWER-Gills: They increase
surface area for gas exchange, convoluted outgrowths containing blood vessels covered by a
