Question 2
pts
(CO1) In the experiments constructed by Pasteur to disprove spontaneous generation, swan-necked
flasks were used. Why was this shape of flask used in this experiment?
Correct!
The glass necks needed to be open to the air, yet constructed so that bacteria would settle in the lowest
part of the neck.
These flask shapes were the easiest and cheapest to produce.
The shape of the glass neck allowed the bacteria into the flask and then into the media.
The shape did not allow any air to go inside the flask but bacteria could
The shape did not have anything to do with spontaneous generation experiment.
