good quiz, thanks :)

Swallowtail

A useful little quiz that contains questions suited to AQA biology on gaseous exchange and absorption.  This topic is also found in specifications. Quizzes are useful to test your understanding after you have revised a topic or to show you which areas need more thorough revision.
