Microbiology is primarily defined as the study of microorganisms, which include bacteria, viruses, fungi, and protozoa. This field of science investigates the characteristics, behaviors, and interactions of these microscopic organisms, which play crucial roles in various biological processes and ecosystems. Understanding microorganisms is vital for several applications, including medical research, agriculture, environmental science, and even the beauty industry, where knowledge of microbial behavior can influence product safety and efficacy.

The other options focus on different scientific disciplines: cosmetic formulations delve into the chemistry and properties of beauty products; human anatomy involves the study of the structure and organization of the human body; and human psychology examines mental processes and behavior. Each of these fields is distinct and does not relate directly to the study of microorganisms, which is why they don’t fit the definition of microbiology.
