Question

Select the correct answer from each drop-down menu. The images show the wings of two different organisms. The wings of the housefly and the bat are _______. This indicates that _______. The two photos show a housefly and a bat.

1) similar in structure
2) different in structure
3) similar in function
4) different in function

Answer 1

The wings of the housefly and the bat are different in structure, indicating different functions. The housefly wing is composed of a chitinous exoskeleton, while the bat wing is made of bones. Both wings are adaptations for flight that evolved independently.

Step-by-step explanation:

The wings of the housefly and the bat are different in structure. This indicates that they serve different functions. The housefly wing is composed of a chitinous exoskeleton, while the bat wing is made of bones. Although both wings are used for flight, they have evolved from different original structures through convergent evolution.

The wings of the housefly and the bat are different in structure but are similar in function. This indicates that, although they perform the same task of flight, they have evolved independently due to convergent evolution, which has led them to have analogous structures. In bats, the wings are formed from skeletal bones covered with skin, representing a modification of the forelimbs, thus sharing a common origin with other mammals. In contrast, the wings of a housefly are made of a chitinous exoskeleton and do not share an evolutionary history with bats or birds.
