Answer:
The option c is partly correct.
Explanation:
None of the statements is completely accurate because:
a. Saurischian dinosaurs include theropod and sauropod dinosaurs, and their common ancestors. Ornithischians comprise neornithischians (ornithopods and ceratopsians), thyreophorans (ankylosaurs and stegosaurs) and heterdontosaurids.
b. Capability to fly has only been documented in fossils belonging to Saurischia (where the birds are also classified in). Feathers, on the other hand, do appear in the two clades. Feathers, however, are not a trait exclusively associated to flight.
c. This is a correct comparison between ornithischians and saurischians in the sense that the attributes do belong to these clades, but when comparing animals there most be a comparison that reflects a pattern. Ornithischians have leaf shaped teeth suited to eat plant material, whereas saurischians have teeth for a carnivore and herbivore diet.
d. Sauropods are saurischians and they evolved herbivory from a meat-eater ancestor.
Answer:
Claws. These strong, curved claws can tear flesh and inflict fearsome wounds. Water Monitors eat only meat and sometimes tackle prey nearly their own size. Claws may allow the Arboreal taxa to physically separate themselves from the larger monitors of the savannah by living in trees, eliminating them as competition and potential predators.
Explanation:
The temperature of tropical areas relative to places more distant to the equator. Another reason why is higher nutrient cycling, which is also an effect of higher temperature.
