Any material has a chemical composition; potatoes can be tested for residues of pesticides.

Biology is the study of life and living organisms. Chemistry is the study of substances, their composition, and how they interact.
Traditional chemistry deals mainly with the interaction of elements, compounds, and energy. Nuclear chemistry studies the nucleus of atoms, and how it can split, decompose, and interact with energy.
Because everything that you touch, see, smell and feel is made up from atoms. Chemistry is the study of how these atoms interact to make new substances, how these substances interact, and how the properties of these substances depend upon their structure. So in a sense, Chemistry explains something about everything!
Social sciences are studies of how people interact. Chemistry- like physics and biology- is part of the "hard" sciences.
This is a pretty good starting description of the science of chemistry.
the answer is chemistry
Chemistry is the study of how atoms and molecules interact with each other. Therefore the essence of biological function is chemistry. The interaction of atoms and molecules obey the rules of physics
Most medicines are made with solutions these are sold or prescribed by a pharmacy you need chemistry to learn how to make medicines or to learn its function. My answer is not 100% accurate only a guess!
A chemistry course will usually focus on the periodic table of elements and how they interact with the world around them. Experiments may be done to illustrate some of these reactions.
An example of psychology is studying how different parenting styles affect a child's development. An example of chemistry is researching how different compounds interact with each other in a chemical reaction.
