Question

The human body is organized into the following structural levels (smallest to largest):

A) molecules: atoms: organs: systems: tissues: cells.
B) atoms: molecules: cells: tissues: organs: systems.
C) organs: tissues: molecules: systems: atoms: organs.
D) atoms: cells: systems: tissues: molecules: organs.

Answer 1

Option (B), The human body's organization from smallest to largest is atoms, molecules, cells, tissues, organs, and organ systems.

Step-by-step explanation:

The organization of the human body can be understood as a series of structural levels starting from the simplest to the most complex. The correct sequence from smallest to largest is atoms, molecules, cells, tissues, organs, and organ systems. Each level builds upon the previous one to form the next level of complexity.

Atoms combine to form molecules; molecules combine to form cells; cells are organized into tissues; tissues come together to form organs; organs are grouped into organ systems; and finally, organ systems work together in an organism.
