What are the special features of multicellular animals in comparison to unicellular organisms?
What are the major problems for gas exchange in terrestrial organisms?
What are the three main types of respiratory surface in animals?
What special features might the most advanced multi-cellular organisms have for gas exchange?
How does gas exchange occur in amphibians?
