Yoel collected data on the size of green anole toe pads.

• A. Forming and Testing Hypothesis
• B. Data Collection and Analysis
• C. Peer Review
• D. Field Observation

Answer: (A)

In science, studying a trait like toe pad size typically starts with a testable idea about how that trait affects function, such as grip or adhesion on different surfaces. Collecting measurements to see whether toe pad size correlates with performance is the step of testing that idea. This activity shows proposing a prediction and then gathering data to determine if the prediction holds, which is the essence of forming and testing a hypothesis. While simply collecting data is part of the process, the crucial element here is using the data to evaluate a specific hypothesis about toe pad size. Peer review would come later as others assess the work, and field observation would be more about recording what happens without a stated predictive idea.
