What Happened In Experimental Group In Spallanzani's Experiment?
Broth Remained clear.
When did Lazzaro Spallanzani conduct his experiment of spontaneous generation?
whu u..
What question was spallazanis experiment designed to answer?
Spallanzani's experiment was designed to disprove the spontaneous generation of microbes in the air.
What question was Spallanzani's experiment designed to answer?
It was to answer whether or not Spontaneous generation is possible or not.
What did Lazzaro Spallanzani contributes to microbiology?
He repeated John Needham's experiment in which nutrient fluids (Chicken broth) was put into a sealed flask then heated. The nutrient medium could be stored and microoganisms did not arise from it. This experiment disproved the Spontaneous Generation and paved the way for Pasteur's research. Spallanzani was largely criticised under claims that microorganisms needed oxygen to survive. He was also a pioneer in the fertilization an experiment which he produced with frogs. :) hope that helps.
What is the controlled variable in Spallanzani experiment?
sealing of flask

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.
What are the contolled variables in spallanzani's experiment?
flasks, broth, time, location, time, temperature.
What is Pasteurs experiment?
Showed that sterile broth remained free of microorganisms until exposed to air.
Why did spallanzani boil broth in his experiment?
To kill any organisms that may have come in through the air.
What did people think about cells Before pasteurs experiment with beef broth and S-shaped tubing?
nonliving things Stupids
What question was Spallanzani's experiment designed to answer?

Did Spallanzani's experiment disprove the hypothesis that microorganisms could arise spontaneously from a vital force contained in the air?
No, it didn't disprove the hypothesis.
