They are composed of the same types of proteins.
B
They have identical chemical compositions.

They are homologous structures due to common ancestry.
D
They are analogous structures due to similar functions.
Verified step by step guidance
1
Understand the concept of homologous structures: In biology, homologous structures are anatomical features in different species that have a similar form or function due to a common evolutionary ancestor.
Recognize the role of organic chemistry in biological structures: Organic chemistry studies the structure, properties, and reactions of organic compounds, which are the basis of all living organisms.
Identify the proteins and chemical compositions: While proteins and chemical compositions are important, the similarity in structures like the wing of a bat and the fin of a whale is not primarily due to identical proteins or chemical compositions.
Distinguish between homologous and analogous structures: Homologous structures arise from a common ancestry, whereas analogous structures arise from convergent evolution, where different species develop similar features independently due to similar environmental pressures.
Conclude that the wing of a bat and the fin of a whale are homologous structures: This is because they share a common evolutionary ancestor, which is why they have similar anatomical features despite serving different functions.
