One can detect bacteria in water by using various methods such as culturing samples on agar plates, using molecular techniques like polymerase chain reaction (PCR), or using portable testing kits that detect specific bacterial markers.
One can detect E. coli in a sample by using methods such as culturing the bacteria on agar plates, performing polymerase chain reaction (PCR) tests, or using immunological techniques like enzyme-linked immunosorbent assay (ELISA).
Unopened agar plates are typically referred to as "sterile agar plates."
To determine if bacteria are present in environmental samples, you can perform tests such as culturing the samples on agar plates, using molecular techniques like PCR, or using biochemical assays to detect specific bacterial markers.
It gives microbiologists a way to grow bacteria on a solid medium. This is important if you want to be able to obtain a pure culture, without a solid medium to grow bacteria it would be nearly impossible. On a solid media a single colony can be isolated and used to innoculate a further plate or broth culture. All the bacteria present in a colony should be decendents of a single organism and so be genetically identical. To obtain a pure culture in liquid media, you would have to do numerous serial dilutions which is very labor intensive compared to streaking a solid medium. Even after many serial dilutions there would be no way to ensure a pure culture.
One way to detect starch hydrolysis is to observe a zone of clearing around the bacterial growth on starch agar plates. This clearing indicates that the bacteria produced amylase, which broke down the starch in the agar. Additionally, testing for the presence of reducing sugars, such as glucose or maltose, could also indicate starch hydrolysis.
A microplate reader is a laboratory instrument which helps to detect chemical, physical or biological events samples in microtiter plates. These are most commonly used in research and drug discovery.
they have machines that can detect movement in tectonic plates
Cascade
Geologists use instruments like GPS receivers and seismometers to study the shifting of tectonic plates. GPS receivers measure the movement of the ground surface, while seismometers detect seismic waves generated by plate movements. These tools help scientists monitor and understand the dynamics of plate tectonics.

The Earth's plates move very slowly, so the effects are difficult to notice except at the plate boundaries. Modern measuring techniques can detect the movements however.

For photographic plates silver halides are used.
Yes, refrigerated agar plates should be brought to room temperature before applying samples. This helps prevent condensation from forming on the surface of the agar, which can interfere with the growth of microorganisms and lead to inaccurate results. Allowing the plates to equilibrate to room temperature also ensures optimal conditions for microbial growth.
Basically releasing electrons from a chemical reaction which is replenished when lead plates are charged.
