Cytochrome c is a protein made up of 104 amino acids. It is found in the mitochondria and aides in the electron transport chain during cellular respiration. The data table represents the number of amino acid differences in cytochrome c between organisms A, B, C, and D.

The phylogenetic trees represent possible interpretations of the data in the chart.

What is the best inference about biochemical relationships that could be made from this model?

• The amino acid sequences of a lancelet and a tuna are more similar than that of a tuna and a salamander. This is due to the lancelet and the tuna both residing entirely in water while the salamander can survive on land.

• The amino acid sequences of a salamander and a turtle are less similar than that of a turtle and a leopard. This is due to the turtle and the salamander both being adapted to life in water or land.

• The amino acid sequences of a lancelet and a tuna are less similar than that of a tuna and a salamander. This is due to the lancelet and the tuna splitting from a common ancestor longer ago.

• The amino acid sequences of a salamander and a turtle are more similar than that of a turtle and a leopard. This is due to the turtle and the salamander both being adapted to life in water or land.
