Fig. 2.1 shows a giant panda feeding on bamboo plants.
Fig. 2.2 shows a red panda, Ailurus fulgens, together with a polar bear, Ursus maritimus.

State one dietary component that is more likely to occur in bamboo plants than in fish.
(b(i))[2]
State two visible features in Fig. 2.1 and Fig. 2.2 that show the three animals belong to the same vertebrate group.
(b(ii))[5]
Discuss the evidence supporting and opposing the idea that the giant panda is more closely related to the red panda than to the polar bear. In your response, use the information in Fig. 2.1, Fig. 2.2 and Fig. 2.3.
(b(iii))[1]
State one additional type of evidence that is used to classify species.
