Question

7. EVALUATING METHODS Clean rooms used

for sterile biological research are sealed and

operate at slightly above atmospheric pressure.

Explain why.

Answer 1

Clean rooms are used for biological research in order to prevent the research from contamination of other microorganisms.

Step-by-step explanation:

Rooms were cleaned before any biological research in order to reduce the intervention of other microorganisms in the research and made the research proof from any impurities. These labs have high atmospheric pressure which decline the growth of microbes and the research will be done in a better way.
