Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biochemistry is the study of chemical processes within and relating to living organisms It focuses on understanding how biological molecules give rise to the processes that occur within living cells and between cells which in turn relates greatly to the study and understanding of tissues, organs, and organism structure and function. Biochemical processes give rise to the complexity of life. Hence, the study of the physicochemical nature of bio-molecules is biochemistry.

So, the correct answer is 'biochemistry'.
