The term "Chemistry and Biology" refers to two separate but related scientific disciplines. Chemistry is the study of matter, its composition, properties, and behavior, as well as the changes it undergoes during chemical reactions. Biology, on the other hand, is the science that deals with living organisms and their interactions with each other and their environment. It includes the study of cells, genetics, evolution, ecology, and physiological processes. When used together, "chemistry and biology" refers to a broad range of scientific fields including biochemistry, which combines the principles of chemistry with those of biology, as well as other interdisciplinary areas such as neurobiology or environmental science that involve elements of both disciplines.
