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.
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.

Station K: Living Things 2 1 3 Domain Bacteria Domain Archaea Domain Eukarya 4 5 Kingdom Eubacteria Kingdom Archeabacteri 6 Kingdom Protista 7 8 9 10 11 12 Kingdom Plantae Kingdom Fungi Kingdom Animalia Label #1 2 3 as Prokaryotic (P) or Eukaryotic (depending if organisms within this group lack an organized nucleus or have one) Label #4 5 6 as which groups inhabit extremely harsh environments or not Label #7 8 9 as which group(s) have a cell wall or lack a cell wall. Label #10 11 12 as which group is autotrophic (producers) or heterotrophs (consumers, including decomposers) Where would you put viruses in this classification schema? Explain your answer.
