Final answer:
Scientists may summarize their experimental results in an equation, which is a concise description of natural behavior. This summary can evolve into a law or theory based on the reproducibility and testing of the evidence.
Step-by-step explanation:
After many experiments, scientists may summarize results in a c) Equation which is a description of how nature behaves. This process often follows extensive experimentation, wherein the research method includes the sequential steps of forming a hypothesis, performing an experiment, analyzing results, and drawing a conclusion. When experimental data is collected and found to be reproducible, it can be summarized in a scientific law, which is a verbal or mathematical description allowing for general predictions about natural phenomena. A scientific law simply states what happens, without delving into the reasons why it happens. In contrast, a scientific theory is a thoroughly tested and confirmed explanation for a set of observations or phenomena, offering an understanding of the natural universe at a deeper level.
