Dr. Sattari and the genetic researchers at Bay Medical Company have determined the proteins of each spider offspring. Review the results and then answer the question below.

In previous lessons, you used the Sim to compare spiders with different traits for the same feature. We observed that spiders with different traits had different proteins in their cells.

We also noticed that some organisms can have different proteins in their cells for a particular feature (like those with medium silk flexibility).

Today, we’ll use our Sim to better understand what determines traits at the molecular level. To do this, you’ll be adding different proteins to a spider’s cell to observe how they affect that spider’s trait.

1. Launch the Simulation.

2. Then, complete the following table by completing the tests.

3. Reset the Sim before doing the next tests.

For the testing part, you need to add the protein then record the results.

Greg - adding Protein 2

Ruby and Otis - adding Protein 1
