so it can be more accurate that's why they conduct multiple experiments and if you just rely on one you have a better chance of getting it wrong
Scientists may choose observational studies over experiments when it is impractical or unethical to manipulate variables or assign subjects to different conditions. For example, studying the effects of smoking on health outcomes requires observing existing behaviors rather than randomly assigning individuals to smoke or not. Observational studies are also useful for examining real-world scenarios and long-term effects where controlled experiments are not feasible.
use of factorial experiment instead of single factor experiments
A tool that scientists would be least likely to use in a lab is a kitchen blender. While it may be useful for mixing certain substances, it lacks the precision and specialized functionality required for scientific experiments. Instead, scientists typically use more specialized equipment like centrifuges or vortex mixers that are designed for specific laboratory tasks.
They use the SI units, so they can compare conclusions in their experiments, and understand each other. Instead of using different types of measurements, they can't understand, they use the same.
Is the method scientists use to study the natural world
Because of the vastness of outer space and the difficulties it poses for survival, scientists generally can't conduct laboratory experiments to explore it. Instead, they must depend on upon their observations.
Earth scientists often conduct investigations instead of controlled experiments because they are studying natural processes that are complex and difficult to replicate in a controlled setting. The Earth's dynamic and interconnected systems are influenced by various factors that are constantly changing, making it more practical to observe and analyze real-world phenomena in their natural context.
Watson and Crick did not conduct any experiments to discover the structure of DNA. Instead, they used data from existing research and their own ingenuity to propose the double-helix model of DNA. It was based on Rosalind Franklin's X-ray diffraction images and experimental data collected by others.
Random assignment to treatment groups and manipulation of an independent variable are characteristics of experiments that are not typically seen in surveys. Surveys usually involve self-reported data collection and do not involve direct intervention or control over variables like experiments do.
These scientists were called "Naturalists"
Watson and Crick did not conduct experiments of their own to discover the structure of DNA. Instead, they used existing data, particularly Franklin's X-ray diffraction images, to propose the double helix model of DNA in 1953. Their model was based on analyzing and interpreting the data with the help of Chargaff's rules.
The full quetion is:Why are controls not needed in the arthropods experimentA some experiments cannot have controlsB All experiments must use controlsC compare treatments to each other instead of to a controlD hypothesis is not falsifiableThe treatments in this experiment can be compared to each other instead of to a control.

No, this is a very complex question and beyond the scope of this site. I urge you to pick up a book on Physics and read it.New discoveries MUST adhere to old laws discovered even hundreds of years ago unless they can come up with proofs (very difficult) that it is wrong. This is a very simplified answer.
Multiple generators are when you use several smaller generators instead of one larger one. For example, you might use multiple 10Kw generators instead of one 30Kw generator.
No, No; They Do Not: Bad Question. They Do Both. Obviously, Experiments upon real systems have been conducted for Eons before Computers came into being. PLEASE REFRAME YOURSELF.
