Question

this branch focuses on the processes inside living things such as how thinking, digestion, and healing work. choose analytical chemistry biochemistry organic chemistry inorganic chemistry physical chemistry theoretical chemistry

Explanation:

Biochemistry is the study of chemical processes within and relating to living organisms. It focuses on understanding how biological molecules (such as proteins, nucleic acids, carbohydrates, and lipids) interact to carry out life's processes like thinking (involving neurotransmitter chemistry), digestion (enzymatic breakdown of food), and healing (immune - system and tissue - repair related chemical reactions). Analytical chemistry is about analyzing substances (composition, structure), organic chemistry is about carbon - containing compounds (not specifically life processes), inorganic chemistry is about non - carbon compounds, physical chemistry is about the physical properties and behavior of chemical systems, and theoretical chemistry is about using theories and models (not focused on life processes).
