How is the experiment performed by Louis Pasteur similar to the experiment performed by Francesco Redi?
Both Louis Pasteur and Francesco Redi conducted experiments to challenge the idea of spontaneous generation. Redi's experiment used decaying meat in covered and uncovered jars to demonstrate that maggots came from flies, not spontaneously from the meat. Pasteur's work with broth in swan-neck flasks showed that microorganisms were introduced from the air, rather than arising spontaneously, when the broth was left exposed. Both experiments provided crucial evidence supporting the theory of biogenesis, the idea that life arises from existing life.
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.
Why is Elodea placed in both flasks?
Elodea is placed in both flasks to show how aquatic plants release oxygen during photosynthesis. By comparing the presence of bubbles in the light and absence of bubbles in the dark, one can observe the effect of light on the process of photosynthesis in Elodea.
Who was more important Jenner or Pasteur?
They both made amazing discoveries and Koch did developed on Pasteur's ideas, BUT without Pasteur none of Koch's ideas would have gone far because Pasteur developed the germ theory which explains illness and without discovering illness then Koch's discovery would have never happened. Pasteur was the scientist that set the building blocks of this whole theory of germs, disease and illness, there were many people that wanted to expand on Pastures theory and so we don't really need Koch as much as we need Pasteur:)
Will salt water boil or will regular water boil?
Both salt water and regular water will boil. However, salt water will have a higher boiling point than regular water due to the presence of salt in the solution.
What was the independent variable in Pasteur's experiment?
The independent variable in Pasteur's experiment was the type of flask used to hold the broth. He tested both open-topped flasks and swan-necked flasks to determine which allowed the growth of microorganisms.
What purpose did boiling the meat broth serve in both spallanzani and pasteur experiments?
Boiling the meat broth killed any existing microorganisms.

Which two scientists performed experiments showing that life comes only from preexisting life?
Louis Pasteur and Francesco Redi are two scientists who performed experiments that supported the idea that life can only arise from preexisting life. Pasteur's experiments with sterilized broth and Redi's experiments with sealed jars and decaying meat both demonstrated the principle of biogenesis.

What will happen if you increase both the pressure and temperature of a liquid?
It will boil
Can beef broth substitute chicken broth?
Physically yes. There isn't very much of a chemical difference between the two (i.e. your dish won't explode if you substitute beef for chicken). However, your dish will taste very different, as beef broth is generally heavier and saltier tasting.
