Biology is defined as the study of life while psychology examines the human mind and its processes, especially those affecting behavior. Biological perspective links biology and psychology by focusing on the analysis of human behavior based on biological and physical evidence.
Why is biology important? As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life.
Chemical biology deals with how chemistry can be applied to solve biological problems while biochemistry is the study of the chemistry of biology. In general, the chemical biology major focuses on small molecules while the biochemistry major focuses on proteins and nucleic acids.
