Why was pasteurs experiment better than spallanzanis?
Pasteur's experiment demonstrating spontaneous generation was considered better because he designed a more controlled experiment with swan-necked flasks that allowed air in but prevented microbes from entering. This disproved the theory of spontaneous generation more conclusively than Spallanzani's experiment which critics argued could have been affected by lack of oxygen.

Why was the conical flask heated in a pressure cooker in Louis pasteurs experiment?
In Louis Pasteur's experiment, the conical flask was heated in a pressure cooker to sterilize the broth inside by killing any microorganisms present. The high temperature and pressure created an environment that prevented contamination during the cooling process, allowing Pasteur to demonstrate that spontaneous generation was not occurring. This method ensured that only the microorganisms introduced afterward could grow, supporting his germ theory of disease.
What was Louis pasteurs independent variable in his spontaneous generation experiment?
In Louis Pasteur's spontaneous generation experiment, the independent variable was the exposure of nutrient broth to air. He used swan-neck flasks to allow air in while preventing microbial contamination from dust and particles, which allowed him to test whether microorganisms would spontaneously generate in the broth. By comparing flasks with and without exposure to air, he was able to demonstrate that microbial growth occurred only in the flasks that were exposed to the air.

How did Pasteurs experiment answer the objections raised by supporters of the vital force hypothesis?
Pasteur's experiment permitted air from the outside to mix with air from the inside, which would have allowed any "vital force" to enter and cause the broth to become cloudy if there were such a "vital force.
