Question

2 multiple choice 0.8 points how did the swan - necked flasks disprove the theory of spontaneous generation? the shape of the neck allows maggot to grow on meat the shape prevents the \life force\ to enter the flask the flasks allow the pasteurization of the broth the swan - necked flask trap the microbes, blocking them from reaching the broth

Explanation:

The swan - necked flasks were designed in such a way that air could enter but airborne microbes were trapped in the curved neck and could not reach the sterile broth inside. This showed that without the introduction of pre - existing microbes, no life spontaneously generated in the broth, thus disproving the theory of spontaneous generation.

Answer:

The swan - necked flask trap the microbes, blocking them from reaching the broth
