Predict How Pasteur's Conclusions on Spontaneous Generation with Swan Flasks

question 4

Multiple Choice

Predict how Pasteur's conclusions on spontaneous generation with swan flasks would have changed if he worked with and maintained the flasks in a sterile laminar flow hood.

• A) Sterilization of the swan flask solutions would not have been necessary to reject spontaneous generation. If he did sterilize the flasks, the spontaneous generation hypothesis would have been supported.
• B) His incubation times would not have been sufficient to refute spontaneous generation.
• C) Pasteur's flasks never would have putrefied, and the experiment would not have refuted spontaneous generation.
• D) Viruses would have still been present, and his conclusion would have been unchanged.

Definitions:

Symmetrical

Characterizing a shape or distribution that is evenly balanced around a center point or axis, so that the pattern on one side mirrors the pattern on the other.

Bimodal

Bimodal describes a distribution with two different modes, or peaks, in a frequency distribution chart.

Asymmetrical

Lacking symmetry; not identical on both sides of a central line.

Unimodal

Unimodal refers to a distribution or dataset that has only one mode or peak, representing the most frequent value.
