Tera performed multiple experiments to determine the best growing conditions for Azaleas. In one experiment, she tested the effe
ct of using different types of soil. In another experiment, she tested the effect of exposing the plants to varying amounts of light. And, in another experiment, she tested the use of different amounts of fertilizer. Once she completed her experiments, Tera recorded all of her observations before making a conclusion. This scenario suggests that
A.scientific questions are often solved by performing a single experiment
B.scientific hypotheses should be made after reaching a conclusion.
C.scientific evidence includes observations, data, and personal opinions
D.scientific explanations are based on evidence, or data.
Option D. The scenario suggests that scientific explanations are based on evidence, or data.
Explanation:
Before making a conclussion or giving an explanation on the experiment made, Tera performs mutiple experiments with different variables and then records all of the obserations made during the experiments, to be able to make a conclussion. This suggests that scientific explanations come as a result of evidence or data, as Tera's recorded observations will show.
