Question
Why is it important to 'Work in the flame zone' when manipulating cultures according to aseptic technique guidelines?
Correct Answer
Option B is the correct answer.
Detailed Explanation

Hint
The heat from the Bunsen burner creates an upward air current, which helps to maintain a sterile working environment around the manipulation area.
