Question

Kangaroo

Which hind leg measurement is most likely from an adult animal with a hind leg that
is homologous to the kangaroo hind leg?
O a grasshopper leg 2 cm long
a rabbit leg 8 mm long
O a bullfrog leg 30 cm long
O a crab leg 50 mm long

Answer 1

O a bullfrog leg 30 cm long

Answer 2

The hind leg of a kangaroo is a long and powerful structure that is specialized for hopping and jumping, so it is most likely to be similar in structure and size to other hind legs that are adapted for similar types of movements. From the options given, the measurement that is most likely to be from an adult animal with a hind leg that is homologous to the kangaroo hind leg is:

• a bullfrog leg 30 cm long

This is because bullfrogs are known for their powerful legs, which they use for jumping and swimming. The length of 30 cm is also more comparable to the size of a kangaroo hind leg than the other options.
