the control group, but the independent variable is manipulated
peer review - ANSWERa mechanism used for policing personal or group bias and

what role does peer review play in the scientific process - ANSWERa way for
scientists to receive review and input from other scientists on their results
scientific fact - ANSWERa direct and repeatable observation of any aspect of the
natural world
, scientific theory - ANSWERmajor idea that has been supported by many
observations and experiments
