Solutions

Expert Solution

Option E

Homologous organs are those which have the same function but different structures.

Mouthparts and Wings of insects have different structures and different functions. Therefore they are not homologous organs.

Vertebrate front legs, hind legs, and wings of insects have different functions and different structures. Therefore they are not homologous organs.

Wings of insect are not modified forelimbs like birds. They are only an extension of cuticle and help in flight. Wings of insects and birds are homologous organs because they have different structure but perform same function.
