The Amino Acid Sequences page shows you the amino acid sequences for the same protein in four different organisms, which we will start out by calling Organism A, Organism Organism C, and Organism D. The protein is cytochrome c, a protein found in the mitochondria of many organisms. Since this protein has a long amino acid sequence, only of the full sequence is shown across the 2 rows shown for each organism Use the data sheet to record your findings for Exercise 1. Compare the sequence for Organism A to that for Organism B. How many differences do you find? Be sure to look at both rows providedRecord the number of differences on your data sheet 2. Repeat this exercise, this time comparing the sequences for the protein in Organisms A and C. Record this on the data sheet. 3. Record the number of differences for Organisms A and D. 4. Record the number of differences for Organisms B and C. 5. Record the number of differences for Organisms B and D. 6. Record the number of differences for Organisms C and D. 7. The four organisms here are a gorilla, a human being, a kangaroo, and a chimpanzee. From the evidence you collected, identify which organism is the kangaroo . Explain how you came to this conclusion and how your conclusion was based upon the assumption of evolution
