Because computer models can show results of experiments - without risking harm to people. For example, a computer can simulate what would happen when combining drugs for specific treatments - without harming patients.
The scientist is conducting experiments in the laboratory to test hypotheses and gather data for research purposes.

Starting the experiment without clearly defining the research question and objectives would not be an appropriate first step. It's crucial to have a clear understanding of what you want to investigate and achieve before conducting any experiment.

They DON'T have to. They use models to save time and money - but the results are always tentative.
The methods section allows other scientists to repeat an experiment.
They first state their question. Next hypothesize. Then research. Then materials and procedures.
You should use research and investigation to solve that problem.The scientist used research and investigation to perform her experiment. Research and investigation are the foundations of science.
A quasi-experiment is an experiment where you cannot randomly assign people to groups. For example, you are either female or male. You could not assign a people as a female when they are not when conducting and experiment.
