How did the design of Pasteur's flaskhelp him successfully refute the hypothesis of spontaneous?
The design of Pasteur's flask, with its long, curved neck, allowed air to enter the flask but prevented dust and microorganisms from falling into the sterile broth. By demonstrating that sterile broth remained free of microorganisms unless contaminated by outside sources, Pasteur refuted the hypothesis of spontaneous generation.

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.

What is Pasteurs experiment?
Louis Pasteur's experiment on spontaneous generation in 1861 involved boiling broth in a flask with a curved neck to prevent dust particles from entering. The broth remained uncontaminated, disproving the theory of spontaneous generation and supporting the idea of biogenesis, which states that living organisms can only arise from preexisting living cells.

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.
