This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What controlled comparison will help you connect an animal's visible structure with a job it helps the animal perform?
Getting the simulation ready…

2Say what will happen, then run it
3Finish: say what you found

Select the measured comparison that directly addresses the prediction.
Name the changed condition, cite one result, and connect it to this goal: Connect an animal's visible structure with a job it helps the animal perform.
Your controlled comparison, measured result, revised model, and transfer claim become inspectable scientific evidence.
