If nothing is growing in your flask then that means no organisms came from non-living matter, therefore the idea that organisms come from non-living matter is disproved.

Which theory did pasteur disprove by using boiled beef broth and a flask with s-shape tubing?
spontaneous generation
Which theory did pasteur disprove by using boiled beef broth an a flask with S-shaped tubing?
Pasteur disproved Theory of spontaneous generation. (Cells came from non-living things)
What variables did Pasteur change in his experiment to test the hypothesis of spontaneous generation?
The shape of the flask!
Who was The idea of spontaneous generation disapproved by?
Louis Pasteur with the S-shaped neck flask
How Louis Pasteur disprove the theory of abiogenesis?
By actual experimentation, the great French scientist Louis Pasteur disproved this false theory of spontaneous generation.Abiogenesis is not the same as spontaneous generation! Spontaneous generation actually posits that full born organisms come from miasma and the like. Abiogenesis posits by hypothesis that life is of simpler organic constituents.Pasteur then entered a contest sponsored by The French Academy of Sciences to disprove the theory of spontaneous generation. Similar to Spallanzani's experiments, Pasteur experiment, pictured in Figure 1-6, used heat to kill the microbes, but left the end of the flask open to the air. In a simple, but brilliant modification, the neck of the flask was heated to melting and drawn out into a long S-shaped curve, preventing the dust particles and their load of microbes from ever reaching the flask. After prolonged incubation the flasks remained free of life and ended the debate for most scientists.Source: [related links]Abiogensis is not the same as spontaneous generation.Pasteur's law only disproved the (then current) idea that life forms such as mice, maggots, and bacteria can appear fully formed. It does not say that very primitive life cannot form from increasingly complex molecules.
How did the observation for flasks 2 disprove spontaneous generation?
The observations disproved spontaneous generation because nothing happened. There was nothing generated in flask two, therefore, it disproves the theory.
Which theory did pasteur disprove by using boiled beef broth and a flask with s shape tubing?
spontaneous generation
Which theory did pasteur disprove by using boiled beef broth and a flask with s-shape tubing?
spontaneous generation
What reason did Pasteur do his experiment with flask?
He wanted to disprove spontaneous generation; that micro organisms were not carried by air, but were deposited from dust.

How did the design of Pasteur's flask help him successfully refute the hypothesis of spontaneous generation?
With previous attempts to disprove spontaneous generation, they argued that nothing was showing up because when something did, it suffocated. With a swan necked flask, as it's called, air could come in and out of it while the bend in the neck stopped airborne bacteria from infecting the broth.

How did the designs of Pasteur flask help him successfully refute the hypothesis of spontaneous generation?
It showed that microorganisms can only enter the flask as airborne particles.

How did pasteur settle the spontaneous generation argument?
Quite. By sealing meat away from atmosphere he showed that maggots do not spontaneously generate out of meat not landed on by egg laying flies.PS: Abiogenesis is not spontaneous generation!
