Incorrect As animals moved from aquatic to terrestrial environments, evolutionary refinements
required a shift from gills to lungs. Why? (see book section: Module 22.4)

No. Insects do not have lungs. Many terrestrial organisms, including humans, have lungs for gas
exchange.
13.
Incorrect A series of air tubes that branch throughout the body describes which gas exchange system?
(see book section: Module 22.4)
No. Skin is a surface, not a tube. Once gas enters the body through the skin, it can be transported by a
circulatory fluid or it can diffuse to body tissues.
