Question

what is your hypothesis for this experiment?
a. pillbugs will move away from the choice chamber containing cornstarch, because they are repelled by cornstarch
b. pillbugs will have random movements between chambers, because they are indifferent to cornstarch
c. pillbugs will move toward the choice chamber containing cornstarch, because they are attracted to cornstarch

Explanation:

In typical pillbug (isopod) behavior experiments, pillbugs are often attracted to substances like cornstarch (a food - related or favorable substance for them). Option A suggests they are repelled, which is not in line with common knowledge about pillbug preferences. Option B suggests random movement due to indifference, but pillbugs do show preferences for certain environments/substances. Option C states they move toward cornstarch because they are attracted, which matches the expected behavior of pillbugs towards a substance like cornstarch (as it can be related to food or a favorable micro - environment).

Answer:

C. Pillbugs will move toward the choice chamber containing cornstarch, because they are attracted to cornstarch
