Description
1)Draw a flow chart that traces a molecule of O2 from the lumen of an alveolus to the binding of the O2 molecule to an Fe atom in the heme group associated with hemoglobin. Include all steps and anatomical structures that must be traversed by the O2 molecule
2)Some mammals (e.g. blue whales, elephants) have evolved relatively large body sizes. List 5 (or more) adaptations that have allowed mammals to evolve large body sizes. For each adaptation, provide a brief explanation of how it enabled the evolution of a large body size.
