Summary Introduction

To match: The experimental groups with their relevant control groups.

Answer to Problem 1DAA

Correct answer:

Experimental group	Control group
A	D
B	E
C	F

Explanation of Solution

The peacock butterfly predator defense experiment is a controlled experiment because it has both experimental and control groups.

The following are the groups that were studied:

Group A: Wing spots painted out

Group B: Wing spots visible and wings silenced

Group C: Wing spots painted out and wings silenced

Group D: Wings painted but spots visible

Group E: Wings cut but not silenced.

Group F: Wings painted, spots visible, wings cut, and not silenced

Group A is an experimental group that has the wings painted, and nothing is mentioned about the noise produced by the wing. Group D has the wings painted, but the spots are visible, and nothing is mentioned about the noise produced by the wing. The wing is the independent variable, and the noise is the dependent variable. Therefore, Group D is the control group for experimental Group A.
Group B is an experimental group that has the wing spots visible, but the noise produced by the wing is silenced. Group E has the wings cut, and the noise produced by the wing is silenced. The wing is the dependent variable, and the noise from the wing is the independent variable. Therefore, Group E is the control group for experimental Group B.
Group C is an experimental group that has the wing painted, but the spots are visible, and the wings are silenced. Group F has the wings painted, spots visible, and cut, and the noise produced by the wing is not silenced. The wing spot is the dependent variable, and the noise from the wing is the independent variable. Therefore, Group F is the control group for experimental Group C.

Group B is an experimental group that has the wing spots visible, but the noise produced by the wing is silenced. Group E has the wings cut, and the noise produced by the wing is silenced. The wing is the dependent variable, and the noise from the wing is the independent variable. Therefore, Group E is the control group for experimental Group B.
Group C is an experimental group that has the wing painted, but the spots are visible, and the wings are silenced. Group F has the wings painted, spots visible, and cut, and the noise produced by the wing is not silenced.
