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.

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.


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.

Is job hunting a science?

No. It is an activity. It is not a science, for the result of a repeated experiment may well differ from other similar experiments. Nor is the result predictable.


Why do scientist use control groups in experiments?

Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.


What is the theoretical probability formula?

The formula depends on the experiment. For example, the answer will differ between a toss of a coin, a roll of a die, drawing a face card or not from an ordinary deck of cards.


How does a Correlational experiment differ from a quasi experiment?

I think it has to do with the quasi you cannot randomly assign people to groups and cannot infer causality. With correlational you are simply examine the relationship between two nominal variables.
