Natural Science CLEP Prep Practice Exam

Chemistry is the study of the properties of matter, which includes its composition, structure, properties, and reactions. Astronomy (option A) is the study of celestial objects such as planets, stars, galaxies, and the universe. Physics (option B) is the study of the behavior and interactions of energy and matter. Biology (option D) is the study of living organisms and their interactions with each other and the environment. While all of these fields overlap in some areas, only chemistry focuses specifically on the properties of matter.
