What is the controlled variable in redi's experiment on spontaneous generation?
The jar that contained the meat with the cover on it.
Francesco Redi disproved the idea of spontaneous generation through an experiment involving?
meat and flies
How did francisco redis experiment change science now?
people believed on spontaneous generation and now they don't after his discovery!
What part of today's scientific method would spontaneous generation be considered?
Spontaneous generation would be considered a hypothesis within today's scientific method that has been disproven through experimentation and observation. Initially, it was a widely accepted idea that life could arise spontaneously from non-living matter. However, rigorous scientific testing and the principles of biogenesis have shown that life only arises from pre-existing life. Thus, spontaneous generation is no longer a valid scientific theory and serves as a historical lesson in the evolution of scientific thought.
Why do you think Redi repeated his experiment a second time under slightly different conditions?
Redi likely repeated his experiment under slightly different conditions to ensure the reliability and validity of his results. By varying the conditions, he could test the robustness of his conclusions regarding spontaneous generation and eliminate any potential variables that might have influenced the initial results. Additionally, repeating the experiment helps to confirm findings and address any skepticism from the scientific community. This rigorous approach enhances the credibility of his work and strengthens the overall argument against spontaneous generation.
What is the controlled variable in redi's experiment on spontaneous generation?
The jar that contained the meat with the cover on it.
What variables present in redi's experiment on spontaneous generation is not a controlled variable?
The presence of living organisms in the meat jars was not a controlled variable in Redi's experiment on spontaneous generation. This variable was dependent on the conditions set by Redi, rather than being controlled by him.
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.
Did Louis Pasteur used a controlled experiment to show that bacteria arise from spontaneous generation?
yes he did
What question was Spallanzani's experiment designed to answer?
It was to answer whether or not Spontaneous generation is possible or not.
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.
In what year did Theodor Swhann conduct an experiment that disapproved the theory''spontaneous generation?
1839
What theory replaced spontaneous generation?
It was by a man who made an experiment that he put 3 jars and
Francesco Redi disproved the idea of spontaneous generation through an experiment involving?
meat and flies
How did pateur's experiment help show spontaneous generation does not occur?
Francesco Redi was the first person to question the validity of spontaneous generation. He was able to disprove the theory by showing that maggots came from fly eggs.
In 1668 Francesco Redi conducted an experiment with jars of meat why is this experiment noteworthy?
he set the foundation on which Louis Pasteur disproved spontaneous generation.
Which scientist performed an experiment that claimed to support spontaneous generation?
> Louis Pasteur (1626-1697) discovered spontaneous generation. Actually, Louis Pasteur (1822-1895) is credited with DISPROVING spontaneous generation, expanding the work of other scientists before him. Aristotle synthesized the theory of spontaneous generation, compiling and expanding on the work of earlier natural philosophers.
