Yes, most of the time they do.

No, not all experiments are performed in a lab. While laboratory experiments are common in fields like chemistry and biology, many experiments occur in natural settings, such as field studies in ecology or social experiments in real-world environments. Additionally, virtual experiments, simulations, and observational studies also contribute to research across various disciplines. The choice of setting depends on the research question and the methods needed to obtain reliable data.
they are conducting experiments.
Experiments can be used to test a hypothesis. For example, an ecologist may set up an artificial environment in a lab to imitate and manipulate conditions that organisms would encounter in the real world. Scientists use experiments to manipulate variables until they find the answer to their question. This is all part of the scientific inquiry.
Research implies on the method of understanding how things work. Experiments are one of the most important utilities of understanding the subject. Experiments also help in proving a fact. Experiments can be compared to evidences in court cases. Until and unless you have enough evidence to support that a particular person is a criminal, nobody would trust you. Similarly, experiments serve as evidences for scientists to prove their views. Sometimes there are no possible experiments to prove a view. During such cases. mathematics is usually used, and the validity is proved by the fact that any further experiments taking into consideration this mathematical outcome turns out to be true. For e.g. the Avogadro's number as 6.023 x 1023. This cannot be proved, since one cannot literally count molecules and ascertain the value. But when later experiments are conducted taking Avogadro's Number as 6.023 x 1023, the experiment is correct. Most of the theories however can be explained by experiments.
You need to explain your question to get a clear answer. "Background" is not usually associated with any "purpose".
volcanoes usually not associated with?
A highly debatable question. Usually red and green are associated with Christmas. Particularly in terms of decorations.
Vault-Tec experiments are usually when the vaults experiment on humans, and turn them into super mutants.
the bagpipes are usually associated with Scotland
High pressure systems are usually not associated with changeable weather.

Please refine the question, your makeing no scence....

Salmonella is the food contamination usually associated with undercooked chicken
The answer to this question is dependent on what type of experiments were performed. All matter is made up of atoms, and they are very small.
