bacteria. He inoculated the nutrient agar in four petri dishes with bacteria. Each of four
paper disks, 1 centimeter in diameter, was soaked in a different mouthwash sample and

Each petri dish was placed in an incubator at a temperature of 37°C for a 24-hour
period. The diagram below represents the sequence of events in this investigation. The
shaded areas in the petri dishes represent regions of bacterial growth.

Comparisons are made between two different organisms by finding the place where the two lines
intersect. The number where the columns and rows intersect shows how many amino acids are
different in the cytochrome c of both organisms. For example, the number of amino acids that are
different when comparing a rabbit's cytochrome c with a tuna's cytochrome c is 17. The larger the
number, the greater the difference in the structure of the cytochrome c molecules of the two
organisms.
39 According to the table, which pair of organisms is least closely related?
A
A rabbit and a chicken
B
A monkey and a turtle
C
A rattlesnake and a tuna
