Explanation:

Question 15

A sagittal section is a vertical plane that divides the body into right and left portions. The other options: "upper and lower" is transverse plane, "front and back" is frontal plane, and "proximal and distal" are directional terms, not plane divisions.

The transverse plane (also called horizontal plane) divides the body into upper and lower parts. Sagittal divides into right/left, frontal into front/back, and "superficial" is a directional term, not a plane.

The correct order of body organization from smallest to largest is: Chemical (atoms, molecules) → Organelle (cell structures) → Cellular (cells) → Tissue (groups of cells) → Organ (groups of tissues) → System (groups of organs) → Organism (whole body). The other options have incorrect sequences (e.g., mixing up order, including non - level terms like "microscopic").

Answer:

B. right and left
