Biology CLEP Prep Practice Exam

The correct answer is Cell Theory because this theory states that all organisms are made up of one or more cells and that cells are the basic unit of structure and function in all living things. While the other options might sound related to genetics or heredity, they do not specifically address the location of the hereditary material within the organism's cells. Homeostatic theory refers to the body's ability to maintain a stable internal environment. Evolution theory explains the diversity and adaptation of species over time. Gene theory states that traits are passed down through specific genes. None of these options specifically mention the hereditary material being found in cells. Therefore, the correct answer is Cell Theory.
