Answer:
D. Human and Chimpanzee are more related than any other pair
Explanation:
The image in this question shows a tabularized information on the amino acid sequence of hemoglobin protein in different species. This amino acid sequence can be used to deduce whether two or more species are closely related or not. The amino acid sequence of the hemoglobin of the different organisms are as follows:
- Human: Lys-Glu-His-Iso
- Horse: Arg-Lys-His-Lys
- Gorilla: Lys-Glu–His-Lys
- Chimpanzee: Lys-Glu-His-Iso
- Zebra: Arg-Lys-His-Arg
Based on the above sequences, it can be observed that the amino acid sequence of humans and chimpanzee are the same with little to no differences while other species that have similar sequences differ in one or two amino acids. This means that Human and Chimpanzee are more related than any other pair.
