Not using the Sim? Watch the video of someone completing the steps of the Sim investigation at tinyurl.com/AMPTR-04, then complete the data table and answer the question below. Sim Investigation Instructions: 1. Launch the Traits and Reproduction Sim. 2. Find three spiders, each with a different trait for silk flexibility (high, medium, or low). 3. Compare the protein molecules in each of the spider's cells. 4. Fill out the table with data from the Sim. 5. Look at the Protein To Trait Example for silk flexibility and answer the question below. Spider's name: Otis Silk flexibility trait: high Protein molecule structure: #2 (comb without teeth) Spider's name: Anne Silk flexibility trait: low Protein molecule structure: #1 (looks like a comb) Spider's name: Ruby Silk flexibility trait: Medium Protein molecule structure: #1 and #2 Review the Protein To Trait Example for silk flexibility. How do the differences in proteins lead to different traits for silk flexibility?
