To answer a specific question, scientist form a hypothesis. If the hypothesis cannot be testable or answered, they'll give you a prediction of what will most likely happen from the results of the hypothesis.
If they can't do a controlled experiment chances are they're advanced and know what they're doing. Depending on the experiment itself, the scientist would have to come up with a procedure that doesn't involve a control. Although there may be no official control, they probably still compare the results to something.

It can be rejected if there is no control variable.
Set up an experiment and a control group, which has an independent and a dependent group

a controlled experiment
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.
If you want to test your hypothesis with a controlled experiment, you should make sure you have only one variable.

control variable
The standard for comparison in an experiment? da that's what they asked don't have to repet the question
It can be rejected if there is no control variable.
Set up an experiment and a control group, which has an independent and a dependent group
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.
no the control is that which is used to test your hypothesis. if mentos would blow up if you use caffeine and you used water, coke, and milk the water would be the control without it you cant do an experiment.
