A science research group is testing a new type of plant food. One trial is conducted in a controlled experiment. The data from the trial show that the plant that received the new food grew faster than the control plant. The group announces that the new plant food makes plants grow faster. What is the main weakness in this scientific claim? The claim is not based on a controlled experiment. The claim is not based on data. The claim is not made by scientific researchers. The claim is not based on evidence from multiple trials.

The claim is not based on evidence from multiple trials.

Explanation:

In a scientific research, it is compulsory to conduct multiple trials before concluding any result. It is because there could be some fault in a specimen used for single trial so a single evidence is not enough. There are different number of minimum trials to be conducted in different situations.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
