Question

Which bottle of the culture set should be drawn first?

a) Bottle with blue cap
b) Bottle with red cap
c) Bottle with green cap
d) Bottle with yellow cap

Answer 1

The bottle with the green cap should be drawn first from the culture set.

Step-by-step explanation:

The bottle that should be drawn first from the culture set is the bottle with the green cap.

This is because the green cap indicates the presence of a nutrient-rich growth medium in the bottle that is ideal for supporting the growth of microorganisms. The other bottles with blue, red, and yellow caps likely contain other components or samples that should be added after the culture has been established in the green-capped bottle.
