18) A Pasteur flask has a(n)
x@ x@ x@ x@

x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

19) Predict how Pasteur’s conclusions on spontaneous generation with swan flasks would have changed if he worke
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

d with and maintained the flasks in a sterile laminar flow hood.
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

A) Sterilization of the swan flask solutions would not have been necessary to reject spontaneous generation. If he
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

did sterilize the flasks, the spontaneous generation hypothesis would have been supported.
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

B) His incubation times would not have been sufficient to refute spontaneous generation.
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

C) Pasteur’s flasks never would have putrefied, and the experiment would not have refuted spontaneous generation.
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

D) Viruses would have still been present, and his conclusion would have been unchanged.
