The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials. The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -

• belong to the same species

• must range great distances to eat

• have very similar skeletal structures

• are descended from a common ancestor

What best describes the hind leg bones seen in the whale?

• The bones are analogous structures to the fins of living fish.

• The bones are vestigial structures that had a function in an ancestor.

• The bones are homologous structures to the wings of butterflies.

• The bones are fossil structures from an extinct ancestor.

What is the best inference about biochemical relationships that could be made from this model?

• The amino acid sequences of a lancelet and a tuna are more similar than that of a tuna and a salamander. This is due to the lancelet and the tuna both residing entirely in water while the salamander can survive on land.

• The amino acid sequences of a salamander and a turtle are less similar than that of a turtle and a leopard. This is due to the turtle and the salamander both being adapted to life in water or land.

• The amino acid sequences of a lancelet and a tuna are less similar than that of a tuna and a salamander. This is due to the lancelet and the tuna splitting from a common ancestor longer ago.

• The amino acid sequences of a salamander and a turtle are more similar than that of a turtle and a leopard. This is due to the turtle and the salamander both being adapted to life in water or land.
