Although scientific theories require extensive observations and experimentation, they can change over time as new evidence is discovered. Scientific laws are principles that are also based on extensive observations and experimentation. Although scientific theories can develop into laws, a theory can only be declared a law if it is proven to be without exception under certain stated conditions. Which of the following is true regarding scientific theories, laws, and knowledge? A. Scientific knowledge must be proven by both scientific theories and laws. B. Scientific theories and laws develop from the acquisition of scientific knowledge. C.
