But in reality biology is much more complex than the physical sciences, and understanding it requires more, not less, brain work. Biological processes of course are consequences of physics and chemistry, which is why we require our biology students to study the physical sciences. But organisms are also historical entities, and that's where the complexities arise. The facts of physics and chemistry are constant across time and space.
Biochemists study the chemistry of living things, like proteins. Molecular biology is the study of genetics and DNA. Cell biology studies the cells that contain DNA, like cancer or brain cells. Anatomy and physiology looks at the structure and function of the human body, where cells assemble into tissues and organs.
