Scientists might conduct multiple trial experiments rather than rely on a single trial because if there are different out comes you can choose the most common one.
Quantum theory was not the result of a single experiment, a single discovery, or even a single scientist. Quantum theory evolved gradually, over several decades.
to isolate and test single variables
The scientist's results are assumed because they are based on a single experiment and may not account for all variables that can affect plant growth. To ensure the validity of the conclusion, the experiment should be repeated multiple times under different conditions to rule out other factors that could influence the plant's preference for sunlight.

Yes. A hypothesis describes what we expect to happen in an experiment. If we do the experiment and something different happens, then our hypothesis is "falsified", or demonstrated to be false. In that case, we'll need to reconsider our hypothesis to determine how it was wrong. We can revise our hypothesis and then conduct a different experiment to test it. It's easy to demonstrate that a hypothesis is incorrect, but it is impossible to prove that it is true.
Scientists test hypotheses using the scientific method. First, there is a question posed about a phenomenon. Then, the hypothesis is created about what the scientist thinks will happen when it is tested. Next, the scientist will create an experiment that will answer the question. With this, the scientist gathers materials and performs the experiment they designed. The experiment should include a control group (one that does not have anything changed), that way you can see the difference between variables. The scientist can only change one variable at a time. As the scientist is conducting the experiment, they should be logging at the results. Once the experiment is done, they should look at the data and see what it proves. Does it prove the hypothesis? Does it go against the hypothesis? Next, scientists generally see how they can apply the results to real life. This goes a little bit beyond your question, but an understanding of the scientific method is important to understanding how hypotheses are tested.
No, it is not possible to observe both the particle and wave aspects of light simultaneously because these aspects are complementary and cannot be observed together in a single experiment. When we conduct an experiment to observe one aspect, the other aspect is not observed.

The most important reason is if a single scientist forms a hypothesis and it is proved by his or her experiment it is still only a hypothesis. Other scientists need to repeat the experiment in every way conceivable to either prove or disprove the hypothesis. Only after the hypothesis has stood up to such scrutiny may it become a theory recognized by the scientific community. Another reason is that some research is simply too daunting and complex for a single person to complete.
In a controlled experiment, a scientist manipulates one variable while keeping all other conditions constant to isolate the effects of that variable. This allows for a clear comparison between the two tests, helping to determine how the single factor affects the outcome. By ensuring that all other factors remain identical, the scientist can attribute any differences in results directly to the variable being tested. This method enhances the validity and reliability of the experiment's conclusions.
