    • C.

      Atoms, tissues, cells, organs

    • D.

      Molecules, cells, tissues, organs

    Correct Answer
    D. Molecules, cells, tissues, organs
    Explanation
    The body is made up of molecules, which are the smallest units of matter. Molecules combine to form cells, which are the basic structural and functional units of life. Cells then organize and work together to form tissues, which are groups of cells that perform specific functions. Tissues further organize and interact to form organs, which are complex structures made up of different types of tissues that work together to perform specific functions in the body. Therefore, the correct order from simple to complex is molecules, cells, tissues, organs.

    • A.

      Under the skin
