Final Answer:
Ranking from smallest to largest: a) Amino acid, g) Red blood cell, i) Virus, l) Mushroom, c) Bacterium, o) Helminth, m) Amoeba, e) Prion.
Step-by-step explanation:
Amino acid (a): Amino acids are the building blocks of proteins and are smaller in scale.
Red blood cell (g): Although larger than amino acids, red blood cells are still relatively small.
Virus (i): Viruses are smaller than many cells but larger than individual molecules.
Mushroom (l): Mushrooms are multicellular organisms, larger than viruses.
Bacterium (c): Bacteria are single-celled microorganisms, larger than viruses but smaller than fungi.
Helminth (o): Helminths are parasitic worms, larger than bacteria.
Amoeba (m): Amoebas are single-celled eukaryotic organisms, larger than bacteria.
Prion (e): Prions are misfolded proteins and relatively small, but larger than individual molecules.
