The diagram illustrating "Structure fits function at all levels of a mouse's organization" depicts several biological organization levels. Which of the following options correctly lists these levels in order from the simplest to the most complex, as shown in the diagram?

  • A: Cell -> Tissue -> Organ -> Molecule
  • B: Molecule -> Cell -> Tissue -> Organ
  • C: Organ -> Tissue -> Cell -> Molecule
  • D: Tissue -> Organ -> Cell -> Molecule

Explanation

The diagram clearly shows the hierarchy from Molecule to Cell, then Tissue, and finally Organ heart . Therefore, the correct order from simplest to most complex is Molecule → Cell → Tissue → Organ.
