why is aspetic technique used to transfer bacteria?

Question

a. to get a variety of different microorganisms in the culture.
b. to transfer only wanted bacteria onto petri dish
c. to get as many pathogens as possible in petri dish.

Answer 1

The correct answer is "b. to transfer only wanted bacteria onto the petri dish."

Aseptic technique is used to prevent contamination during the transfer of bacteria. Contamination can arise from unwanted microorganisms that may be present in the environment or on the equipment being used. By employing aseptic technique, the transfer of only the desired microorganisms can be ensured. This is important in microbiology and other scientific applications where specific bacteria need to be isolated and studied.
