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.
Which two phylogenetic trees represent the data most accurately? (choose 2)
The phylogenetic tree was constructed using derived traits of organisms A, B, C, D, and E. Based on the tree, which two organisms share the most derived traits?
C and D because they share one common branch.
C and D because they are closest to the end of the tree next to each other.
A and B because they share the most branch points.
A and B because they are the pair closest to the center.
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.
According to the cladogram, which organism is most distantly related to the human?
crayfish
grasshopper
perch
