Step-by-step explanation:
The human body is made up of approximately 100 trillion cells that are composed of different molecules. The human body is made up of approximately 100 trillion cells composed of different molecules. Each type of cell has a specific shape and function and is organized into tissues, organs, and organ systems.
These cells are the basic units of structure and function in the body, carrying out various life processes and allowing the body to survive. Each type of cell has a specific shape and function, and they are organized into tissues, which are further organized into organs and organ systems.
