What is the simplest level of structural organization in the human body?

Explanation:
The simplest level focuses on the chemical building blocks—atoms and molecules. Everything in the body starts from these tiny constituents, with water, proteins, lipids, carbohydrates, and nucleic acids forming the molecules that make up all cells and structures. Without this chemical foundation, there wouldn’t be the material to assemble into cells, tissues, or organs. So while cells, tissues, and organs are all essential, they are built from interactions and bonds at the chemical level. The other levels—cellular, tissue, and organ—are progressively more complex arrangements that arise from these basic chemical components.
