A Ribosome

Explanation / Answer

The predicted answer is,

Molecules are arranged from larger size to their smaller size.

Atoms are the smallest entities in the universe. Atoms combine to form molecules. Chemical formula of water molecule is H2O and that of glucose is C6H12O6. So, always glucose molecule will be larger in size than water molecule.

Similarly, Amoeba and Human egg cell are always larger and can be seen with the naked eye. So, they are arranged as largest. And always viruses are smaller than bacteria.

The difficulty was to arrange different cell organeles, RBC, Skin cell nucleus and Mitochondria the most. And the relative position of HIV virus and Ribosome.
