For Francisco Redi's Spontaneous Generation. Which would be considered the control group of the experiment and which would be the variable group? The jars that were sealed shut and the jars that were left open. which is which?
Thanks
In Francisco Redi's experiment on spontaneous generation, the control group would be the jars that were sealed shut, while the variable group would be the jars that were left open.
To determine this, you can analyze the purpose of each group in the experiment. The control group is used as a baseline for comparison, where no changes or manipulations are made. In Redi's experiment, the purpose of the control group, which consisted of sealed jars, was to show that without the introduction of any external factors (such as air or flies), maggots do not spontaneously appear.
On the other hand, the variable group is the group in which the independent variable is manipulated or changed. In this case, the variable group involved the jars that were left open. The purpose of this group was to observe and compare the organism growth, in this case maggots, when exposed to external factors (such as air and flies).
By comparing the results between the control group and the variable group, Redi was able to determine the effect of external factors on the appearance of maggots, disproving the idea of spontaneous generation.
To recap:
- The control group consists of the jars that were sealed shut, which acts as a baseline with no changes made.
- The variable group consists of the jars that were left open, where the independent variable (exposure to air and flies) was manipulated.
