The individuals of all species contain many different protiens or carbohydrates in the cell walls of bacteria, chitin in the external skeleton
5. Vertebrate Adaptions For Terrestrial Life
AP-Biology Essay on vertebrate structural adaptations for terrestrial life. (From an actual past AP-BIOLOGY test) The problems of survival of animals on land are very different from those of survival of animals in aquatic environment. Describe four problems associated with animal survival in terrestrial environments but not in aquatic environments.
