<span>Classical conditioning. Classical conditioning occurs when we link something usually considered "neutral" with a what is called an involuntary response. An example of this would be a student who begins to fear school because of a bully at school. The student associates school with the bully. A well known example of classical conditioning is Pavlov's experiment with his dogs, where the dogs learned to associate the ringing of a bell with eating meat.

Answer:
a. Marigold with no fertilizer
Explanation:
An experiment contains variables including independent and dependent variables. The independent variable is the variable that is changed by the experimenter, which is the TYPE OF FERTILIZER in this case, while the dependent variable is the measured variable, which is the GROWTH OF MARIGOLDS in this experiment.
However, a control group is a group that does not receive any experimental treatment. In other words, the independent variable is unchanged in the control group. The control group is regarded as the "normal" used to compare with the experimental group (group that receives treatment). In this experiment, the group of marigolds that DOES NOT RECEIVE FERTILIZER is the control group.
