How did pasteur solve spallanzani problem of limiting exposure to air?
Pastuer solved Spallanzani's problem by using swan-necked flasks that allowed air to enter but prevented dust and microorganisms from contaminating the broth. This design let him prove that living organisms in the air were the source of contamination, not spontaneous generation.
How did Louis Pasteur experiment differ from lazzaro spallanzani experiment?
Instead of sealing the flask in the experimental group after boiling, Pasteur used a flask with a curved neck, which allowed air inside and outside the flask to mix but prevented microorganisms from entering the body of the flask.
Who proved that bacteria are found in air?
Louis Pasteur proved that bacteria are found in air through his experiments with swan-necked flasks. He showed that when the neck of the flask was broken, allowing air to enter, the broth inside became contaminated with bacteria, demonstrating the presence of airborne bacteria.
Louis Jean Pasteur's accomplishments?
Louis Jean Pasteur pasteurized milk so it is not sour. Pasteur also discovered anaerobiosis, whereby some microorganisms can develop and live without air or oxygen, this is called Pasteurized effect. When Pasteur died on September 28, 1895, he was named a national hero from the French government for his important contributions to science, health, and food safety.
Which is more easily decompose in open or close area?
Organic matter decomposes more easily in open areas due to increased exposure to air, sunlight, and microbial activity. Closed areas, such as landfills or sealed containers, hinder decomposition by limiting these environmental factors.

What scientist responsible for disproving the theory of spontaneous generation?
Francesco Redi, in 1668, showed that abiogenesis of maggots did not occur, and further experiments by Lazzaro Spallanzani (1768) and Louis Pasteur (1861) showed that many of the lifeforms thought "created" were those already invisibly present in the air or in other materials.
Who was the scientist who used s shaped flasks?
Louis Pasteur is the scientist known for using the S-shaped flasks in his experiments on spontaneous generation. By curving the neck of the flask to prevent entry of airborne microbes while allowing the passage of air, Pasteur demonstrated the presence of microorganisms in the air and debunked the idea of spontaneous generation.
What reduces air pollution?
As humans, we can reduce air pollution by limiting our use of energy and polluntants.
How did pasteur's 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.

What causes feta to spoil?
Exposure to air.
Is discoloration of metal by exposure to air?
rust
