Transcription

1 Station A: #1. Write your mnemonic for remembering the order of the taxa (from the broadest, most generic taxon to the most specific). Out to the side of each, write the name of each taxon the mnemonic represents. Put a box around the most generic taxon. Circle the most specific taxon. #2. Write the following list into your notebook. In each group below check ( ) the taxon that has the most members and circle the taxon that has the fewest members: family - genus - phylum - species order - phylum - genus - family genera - domain - phylum - order class - family - phylum - order #3. If two organisms belong to the same order, they must also belong to the same If two organisms belong to the general (genus), they may not belong to the same

2 Station B: Species Human Horse Gorilla Chimpanzee Zebra Sequence of 4 amino acids found in the same part of the hemoglobin molecule Lys Glu His Phe Arg Lys His Lys Lys Glu His Lys Lys Glu His Phe Arg Lys His - Arg #1. In your notebook, draw which evolutionary tree best represents the data in this chart. #2. Choose an incorrect answer and explain in your notebook why it is wrong.

3 Station C: The table shows an amino acid comparison of Cytochrome C, a protein involved in cellular respiration in aerobic organisms. #1. In your notebook, identify the two organisms that are the least alike genetically. Explain why you choose this answer. #2. In your notebook, identify the two organisms that are the most alike genetically. Explain why you choose this answer.

4 Station D: #1. Who is more similar to a gorilla: a chimp or orangutan? In your notebook, explain how you know this is true. #2. What is another comparison you can make about the similarities or differences between the primates shown on this cladogram? Explain your answer in the notebook.

5 Station E: #1. According to this cladogram, who is more similar to a rabbit: a beaver or a cat? In your notebook, explain how you know this is true. #2. What is another comparison you can make about the similarities or differences between the organisms shown on this cladogram? Justify your answer in your notebook.

6 Station F: A student collected this specimen on a field trip. #1. Using the dichotomous key shown, how would you best classify this plant? Justify your answer in your notebook.

7 Station G: A student collected this specimen on a field trip. #1. Using the dichotomous key shown, how would you best classify this organism? Explain in your notebook. #2. How do you know it s not an arthropod? Explain in your notebook. #3. How do you know it s not a mollusk? Explain in your notebook.

8 Station H: Scientists found members of a plant species they did not recognize. They wanted to determine if the unknown species was related to one or more of four known species, A, B, C, and D. The relationship between species can be determined most accurately by comparing banding patters of DNA from a gel electrophoresis. Below is a picture taken of the gel after electrophoresis was run on the unknown plant species and 4 known plant species, A, B, C, D. #1. Draw the following chart in your notebook. Compare the unknown plant to each known species. Write each as a fraction; convert to a percent. Unknown & A Unknown & B Unknown & C Unknown & D Percent similar Check which is most alike #2. The unknown plant species is most closely related to which of the four known species? Explain and support your answer.

9 Station I: Based on their analysis of the differences in amino acid sequences of one kind of protein, scientists prepared the evolutionary tree shown below. #1. According to this diagram, the DNA of which of the following pairs of organisms would you expect to show the greatest similarity? Explain your answer in your notebook. Turtle and rabbit Snake and tuna Horse and donkey Penguin and turtle #2. According to this diagram, the DNA of which pair of organisms would you expect to show the least similarity? Explain your answer in your notebook.
