Complete question:
Experiment 1: Mold Growth on Bread and Fruit
The purpose of this experiment is to analyze the mold growth on bread and apple under different conditions.
After performing the experiment, the student must answer a sequence of questions. One of the questions is "What was the purpose of examining three pieces of bread and three pieces of apple in each treatment?".
Answer:
The purpose of examining three pieces of bread and three pieces of apple is to obtain more precise results in the experiment, with the lower error possible.
Explanation:
Each piece of bread and apple is a replica.
In an experiment, replica refers to the repetition of the basic experiment. Each replica might be considered as a copy of other replicas, and its importance relies on getting a better estimation of the experimental error and obtaining a more precise response or answer to the question. The higher number of replicas in an experiment, the better results will be obtained.
