Answer:
The Louis Pasteur's experiment states that the liquid contamination in flask was caused by certain small particles which are present in the air but not by air itself.
Explanation:
The experiment performed by Louis Pasteur disapproved the theory of spontaneous generation. The closed flask is allowed for oxygen to enter but not dust particles. This flask was free from contamination.
The flask when allowed dust to enter, causes the contamination of broth. This indicates there are some particles in the air which are may be microbes and causing this contamination.
