Answer:
The success of an experiment depends on several factors provided while experimenting like the proper review of the literature and proper information. The given question on soil ecology studies the effect of compost on the growth of several crops. The biologist was not able to reach the best conclusions of their result as their results were inconsistent due to:
1. The experiment was not designed properly as adding nutrients at the same time.
1. Lack of knowledge about the compost they added like the composition of nutrients.
2. The compost added was of different quality.
4. The crops grown were grown in two different soil types- the indoor greenhouse and outdoor farms.
5. Little knowledge about the control and experimental setup.
The pot has a hole
In the bottom of it
Hello. You did not present the experiment to which this question refers, which makes it impossible for me to give you an answer. However, when searching for your question on the internet, I was able to find another question exactly the same as yours, which showed that Rachel was studying the causes and consequences of treating mental illness in patients with generalized anxiety disorder. In this experiment, she gave each participant an untested drug, a placebo and a nocebo and assessed how these substances altered the arousal of the sympathetic nervous system one week before and one week after the study.
If that is the case with her question, the two reactions that Rachel could use to operate the dependent variable would be placebo and nocebo.
We can reach this conclusion because both the nocebo and the placebo do not generate real effects in the participants, but it causes psychological effects, imagined by the patient, against the real medicine. In this case, both the placebo and the nocebo are capable of provoking pisological effects in the excitation of the sympathetic nervous system of the patients. Within an experiment, the variable that has the power to provoke something is the independent variable and it is this variable that allows the researcher to operate the dependent variable. In this case, we can consider that the nocebo and the placebo are the independent variables that can manipulate the dependent variable, which is the sympathetic nervous system excitation.
