Question

c. i will put one pillbug into the choice chamber and see where it immediately goes. 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.

Explanation:

This is a biology experiment testing pillbug habitat preference. A valid choice chamber experiment needs a variable to test preference; having different substrates (cornstarch vs fine sand) creates a testable condition. Options A, B, D do not provide a comparison to measure preference.

Answer:

C. I will put cornstarch on one side of the chamber and fine sand on the other side of the chamber.
