Question

in the viable plate count method, a measured volume of a culture is evenly spread across an agar surface and incubated. each __ represents one __ from the original sample.
a cell; colony
b species;colony
c colony; cell
d cell; cell
e generation;cell

Explanation:

In the viable plate count method, when a culture is spread on agar and incubated, a colony forms. Each colony is derived from one cell in the original sample. A species is a group of organisms, not relevant here. A generation is a time - related concept. So, the correct relationship is colony representing one cell.

Answer:

C. colony; cell
