introduction laboratory simulation what is your experimental setup for the top choice chamber? a. i will put cornstarch on both sides. b. i will leave both sides empty c. i will put cornstarch on one side of the chamber and fine sand on the other side of the chamber. d. i will put sand on both sides what is your control setup for the bottom choice chamber? a. i will put cornstarch on one side and fine sand on the other side b. i will put cornstarch on both sides. c. i will leave both sides empty. d. i will put sand on both sides. e. i will put sand on one side and leave the other side empty. methods reset my notes lab data

Explanation:

For the experimental setup (top chamber), the goal is to test pill bug preference by creating a difference between two sides, so we use a variable (cornstarch vs. sand). For the control setup (bottom chamber), we eliminate the variable to rule out other factors, so we use the same substrate on both sides; using sand on both sides controls for the substrate itself without the test variable.

Answer:

1. Experimental setup: C. I will put cornstarch on one side of the chamber and fine sand on the other side of the chamber.
2. Control setup: D. I will put sand on both sides.
