The graph illustrates the oxygen dissociation curves of haemoglobin in eight species of mammal. Which conclusion agrees with the data in the graph?
- AThe haemoglobin of larger mammals will combine with oxygen at a lower partial pressure of oxygen than that of smaller mammals.
- BThe haemoglobin of larger mammals will release oxygen at a higher partial pressure of oxygen than that of smaller mammals.
- CThe metabolic activity of the mammal is directly proportional to the ability of its haemoglobin to release oxygen.
- DThe size of the mammal is directly proportional to the ability of its haemoglobin to release oxygen.
