In Louis Pasteur's experiments on spontaneous generation, the control group consisted of flasks filled with nutrient broth that were left open to the air, allowing potential microbial contamination. These flasks showed microbial growth, supporting the idea that microorganisms came from the environment rather than spontaneously generated. In contrast, the experimental group used swan-necked flasks that prevented airborne contaminants from entering while still allowing air circulation, which remained free of microbial growth, thus disproving spontaneous generation.
What else can I help you with?
How might the believers of spontaneous generation have disputed redi's conclusion if redi had not used a control group?
Believers of spontaneous generation could have argued that Redi's results were inconclusive without a control group because there was no way to compare if the sealed jars were truly preventing the generation of maggots. They could have also questioned the validity of his experiment and claimed that other factors might have influenced the outcome, thus casting doubt on the idea that maggots were not spontaneously generated in the open jars.
What were Louis Pasteur experimental and control groups?
In Louis Pasteur's famous experiments on fermentation and spontaneous generation, the experimental group consisted of broth that was exposed to air and allowed to develop microbial growth. The control group included broth that was sealed in flasks, preventing exposure to air and microbial contamination. This setup demonstrated that microorganisms originate from other microorganisms rather than spontaneously from non-living matter. Pasteur's work ultimately disproved the theory of spontaneous generation and laid the foundation for microbiology.
In a scientific experiment a control is the part of the experiment that?
In a scientific experiment, a control is the part of the experiment that remains constant and is used as a baseline to compare against the experimental group. It helps researchers determine the effect of the variable being tested in the experiment.
What is a control in an experiment?
The control is what you keep the same through the whole experiment. I'm doing an experiment for a science fair this yer and its: What things can remove permanent marker from fabric. my control would be, the amount of "stuff" i use and the type or marker. hope it helps ♥

Why is redi's experiment on spontaneous generation considered a controlled variable?
Redi showed the need to limit/control outside variables when he covered 1/2 the jars and got different results than the uncovered.

How might the believers in spontaneous generation have disputed Redi's conclusion if Redi had not used a control group?
Believers in spontaneous generation might have argued that Redi's results were inconclusive because he did not account for all possible variables affecting the appearance of maggots in the meat. Without a control group for comparison, they could have claimed that other factors, not just the presence of flies, might have influenced the generation of maggots.
What are the control and experimental groups on Francesco redi's experiment?
In Francesco Redi's experiment, the control group consisted of jars with meat that were left open to the air, allowing flies to access them and lay eggs. The experimental group included jars with meat that were sealed with fine mesh or gauze, preventing flies from reaching the meat. The purpose of the experiment was to demonstrate that maggots on the meat originated from fly eggs and not from spontaneous generation. Redi's findings supported the idea that living organisms arise from other living organisms.

What is the control of a experiment?
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.
Control of ball rebound experiment?
a control is something that stays the same in an experiment
A standard of comparison in an experiment is called the?
it is called the control of the experiment
What does control mean in an experiment?
control means to take conrol in a science experiment
When was fransico Reid's experiment?
It was Francesco Redi's experiment. In 1664 Redi wrote his first work Osservazioni intorno alle vipere(Observations about the Viper). Redi is best known for, published in 1668 as Esperienze Intorno alla Generazione degl'Insetti (Experiments on the Generation of Insects).It proved that flies did not spontaneous generate. He put meat in a flask and covered it with cheesecloth so that air could get in but not flies. The other flask was a control and did not have cheesecloth. Only the flask without cheesecloth had flies.
The standard for comparison in a experiment?
The standard for comparison in a experiment is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
What is the control group and what is it used for?
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
