Course Description

The course outline below was developed as part of a statewide standardization process.

General Course Purpose

Biology 150 serves as an introductory science course that exposes students majoring in Health Sciences to the existence and impact of microorganisms inside and outside the human body system on human health. The course has both lecture and laboratory components. Both these components will emphasize on giving a firm understanding to healthcare practitioners about the aseptic techniques that would assist in limiting the spread of infectious diseases.

Course Prerequisites/Corequisites

Prerequisite: BIO 101 or BIO 141

Course Objectives
