What is the function of the blue dye added to the sample before the electrophoreses is performed?
The blue dye is usually a combination of glycerol and something else. But I believe the most important part is the glycerol. Glycerol is heavier than the buffer that you actually perform the electrophoresis in.
By adding the glycerol to your sample, you give it weight so that it doesn't float around when you're trying to pipette it into your well and so that it will just fall.

What are the rules and regulations of a urine test?
Urine tests are typically performed in a private setting to ensure confidentiality. The individual may be asked to wash their hands before providing a urine sample. The sample is then analyzed for various substances including drugs, proteins, or sugars.
What is function of deproteinizer?
A deproteinizer is used to remove proteins from a sample, such as DNA or RNA extraction, by precipitating the proteins out of solution. This helps to purify the desired molecule and remove any interfering substances before further analysis.
When venipuncture is performed using a lavender vacutainer tube the sample?
When venipuncture is performed using a lavender vacutainer tube, the sample collected is typically used for hematology testing, such as complete blood count (CBC), erythrocyte sedimentation rate (ESR), and blood typing. The lavender top tube contains EDTA as an anticoagulant to preserve the blood sample for these types of tests.

What is the function of gas chromatograph?
A gas chromatograph is used to separate and analyze volatile compounds in a sample. It works by vaporizing the sample and passing it through a column where the compounds are separated based on their chemical characteristics. The separated compounds are detected and identified by a detector, providing information about the composition of the sample.
What is the relation between Sample and population regression function?
The sample regression function is a statistical approximation to the population regression function.
How do you anchor in school function?

How do you calculate sample standard deviation?
Here's how you do it in Excel: use the function =STDEV(<range with data>). That function calculates standard deviation for a sample.
What is color absorption?
Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample. The sample absorbs energy, i.e., photons, from the radiating field. The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum. Absorption spectroscopy is performed across the electromagnetic spectrum.
How can you be tested for alcohol?
Testing for alcohol can be performed with an alcohol breath machine, with a sample of blood drawn, with a sample of urine, with a sample of mouth fluid, or with a sample of sweat.

Would you expect to have different result if we had not heated the food sample solution before heating?
Presumably yes, but given that the question does not actually describe the experiment or observation performed, there is no way to answer this question more concretely.
