Put the following in order from smallest to largest. - protein
- eukaryotic cell (has nucleus)
- virus (NOT alive)
- prokaryote (bacteria, no nucleus)

Protein → virus → prokaryotic cell → eukaryotic cell

Explanation:

This question is asking to place the following components of organisms in an ascending order of magnitude i.e. from smallest to largest.

- Proteins are macromolecules that are found in living cells where they serve different functions. Since they are found inside cells, they are the smallest on this list.

- Viruses are microorganisms considered to be non-living because they do not show characteristics of living things. Viruses are pathogenic organisms that attack living cells. They are the smallest microbes found having sizes in nanometers (nm).

- Prokaryotes are group of organisms with no nucleus e.g bacteria. They possess cells that are smaller than that of eukaryotes.

- Eukaryotic cells i.e. cells with nucleus, have the biggest size of any cell. Hence, they are the largest in the list.

Based on the above description, the ascending order of magnitude is as follows: Protein → virus → prokaryotic cell → eukaryotic cell
