To kill any organisms that may have come in through the air.
What else can I help you with?
What are the contolled variables in spallanzani's experiment?
flasks, broth, time, location, time, temperature.
What Happened In Experimental Group In Spallanzani's Experiment?
In Spallanzani's experiment, the experimental group received boiled broth that was then sealed from external contamination. This group did not exhibit the growth of microorganisms, providing evidence against spontaneous generation.
What is the controlled variable in Spallanzani experiment?
In Spallanzani's experiment, the controlled variable was the type of container used to hold the broth. By using different containers with varying levels of accessibility to air, Spallanzani was able to determine the role of air in the generation of life.
How did Pasteur's experiment differ from spallanzani experiment?
Pasteur's experiment on spontaneous generation showed that microorganisms do not arise spontaneously but are introduced into broths from external sources. Spallanzani's experiment involved boiling nutrient broth in sealed flasks to sterilize it, then observing that no microorganisms grew unless air was allowed to enter the flask, suggesting that microbes were not generated spontaneously but entered from the air.
What was the results and conclusions of the Spallanzani experiment?
Spallanzani's experiment concluded that spontaneous generation of life did not occur. By sealing containers of meat broth and boiling them to kill any existing microorganisms, he prevented the growth of microorganisms within. This demonstrated that living organisms could only arise from other living organisms.
How did Pasteur's experiment differ from spallanzanis experiment?
Pasteur's experiment refuted the theory of spontaneous generation by demonstrating that microorganisms in broth were killed by heat and could only enter through the air. Spallanzani's experiment involved boiling broth in sealed flasks to prevent microorganism entry, concluding that the lack of spontaneous generation was due to the lack of vital force rather than the absence of air.
What purpose did boiling the meat broth serve in both spallanzani and pasteur experiments?
Boiling the meat broth killed any existing microorganisms.
What question was spallazanis experiment designed to answer?
Spallanzani's experiment was designed to investigate whether spontaneous generation of life was possible by showing that microorganisms did not arise spontaneously, but were introduced from the air or other sources.
Where could the organisms have come from in the 1768 broth experiment described?
the organisms could come from the heat in the broth if you boil it,cause if you boil it,it creates organisms. It will only work if you put a cap on top of the bottle you are boiling. the one with the cap on is not cantaminated. The one without the cap is cantaminated and already has organisms in it.so the organisms come from the oxygen in the one where it does not have the cap on
What purpose did boiling the meat serve in both Spallanzani and Pasteur experiments?
Boiling the meat broth killed any existing microorganisms.
How do you get the most nutritional value from food?
Boil it, then drink the broth.
What question was Spallanzani's experiment designed to answer?
It was to answer whether or not Spontaneous generation is possible or not.
