dunnah?? that's why iasked u !! :/
Scientists use acids, bases, and alkalis in their labs for various purposes such as adjusting pH levels, catalyzing reactions, and extracting materials. Acids are used to lower pH, bases to raise pH, and alkalis are a subset of bases that are water-soluble and have a pH greater than 7. They are chosen based on their specific chemical properties to facilitate experiments and research.
In pool maintenance we use a bottle labeled R-004 to test the ph. In chemistry labs, you might use phenolphthalein solution, litmus paper, or other pH test paper, depending on the situation.

No, they code for amino acids (in sequence).
salt. acids can be used to form salt.
Microscopes are very common in any kind of lab. If you get a job where you have to analyze different biological samples will most probably have to use a microscope. Clinical lab technicians, biologists, botanists etc are some of the jobs where you have to use microscopes frequently.
One would use particle counters to determine the cleanliness level in a controlled environment. This includes biotechnological labs, aerospace labs and other fields that are sensitive to environmental contamination.
The increased use of drugs has led to a higher demand for forensic analysis and testing in crime labs in the US. This has resulted in an expansion of resources, technology, and staff in these labs to keep up with the caseload. However, it has also created challenges such as backlogs and delays in processing evidence.
Australian state schools (public schools) do not use corporal punishment. A tiny number of independent schools still use corporal punishment, with the agreement of the parents.
