Natural Science CLEP Prep Practice Exam

Biochemistry is the branch of biology that focuses on the study of energy flow and chemical transformations in living systems. This includes the study of the structure, function, and interactions of biological molecules such as proteins, carbohydrates, lipids, and nucleic acids.

Option B, Paleontology, is the study of ancient life forms through the analysis of fossils. This field is not directly concerned with energy flow and chemical transformations in living systems.

Option C, Entomology, is the study of insects. While this field may involve some studies of energy flow and chemical transformations in insects, it is not the main focus.

Option D, Bacteriology, is the study of bacteria and their effects on living systems. While bacteria do play a role in energy flow and chemical transformations in some living systems, this field is not solely focused on these processes and their mechanisms.
