Question

Microorganisms are typically only visible with a microscope because they are small. Which two categories of organisms or cell types do a majority of bacteria fall?

a. Hepatitis virus (45 nm) and hemoglobin (6.5 nm)

b. skin cell (30 µm) and a red blood cell (8 µm)

c. amoeba (500 µm) and paramecium (60-210 µm)

d. Baker’s yeast (4 µm) and measles virus (220 nm)

Answer 1

C. amoeba and paramecium will fall under bacteria.
considering the given choices,
a. hepatitis virus and hemoglobin: hepatitis is a virus, eventhough it is a microorganism, it is not considered a bacteria because it has no living components inside its cell. a virus basically contains a genetic material(DNA or RNA) enclosed in a protein coat. and hemoglobin is a protein molecule in blood.
b. skin cell and red blood cells: skin cells and red blood cells are componenets of the body that are required for the functioning of body they are not bacteria.
d. bakers yeast and measles virus: even though the bakers yeast is a bacteria, the measles virus is not bacteria
c. amoeba and paramecium: of all the four choices, amoeba and paramecium are considered the bacteria, paramecium is a type of algae. paramecium and amoeba has cellular components that are responsible for the growth and survival.
