Verified
Cytochrome c is a molecule used in the electron transport chain of many organisms. Data regarding differences in the amino acid sequence of cytochrome c show that the sequence in a moth differs from a turtle by 15 about amino acids, while a moth differs from a human by about 30 amino acids. Therefore,
A) this is sufficient evidence to prove the moth is related more to the human than the turtle.
B) turtles evolved before moths.
C) there is no evolutionary relationship between moths, snakes, and humans.
D) in addition to anatomical similarities and fossil data, this provides additional evidence for determining the relatedness between these organisms.
E) biochemical information is not relevant to the evolution of organisms.
Cytochrome C
A small heme protein found in the mitochondria of cells, playing a role in the electron transport chain and the process of cellular respiration.
Electron Transport Chain
A series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.
Amino Acid Sequence
The order in which amino acids are arranged in a protein, dictating the protein's structure and function.

Final Answer :
D
Explanation :
The differences in the amino acid sequence of cytochrome c provide additional evidence for determining the relatedness between organisms, in addition to anatomical similarities and fossil data. However, it is not sufficient evidence to prove that the moth is related more to the human than the turtle, as there could be other factors influencing their evolutionary relationships.
