Which statement is an example of a law? A. Objects tend to resist changes in motion. B. A car’s speed decreases when the brake is applied. C. Characteristics are passed from parents to children through DNA. D. If I add more carbon dioxide to this biosphere, then temperatures will increase.
A is correct because it explains an object’s relationship to motion and can be used to predict the behavior of objects. B is incorrect because it is a specific observation, not a generalized statement. C is incorrect because it explains how characteristics are conveyed, so it is a theory. D is incorrect because it is written as a hypothesis for an experiment, not as a law.
