The nurse is explaining the recommended dietary allowances (RDAs) to a client seeking nutritional counseling.
<h3>What are RDAs? </h3>
The Recommended Dietary Allowances (RDAs) for critical nutrients have been assessed by the Food and Nutrition Board to be sufficient to cover the known nutrient needs of practically all healthy individuals.
<h3>
History of RDAs. </h3>
The first Recommended Dietary Allowances (RDAs) were published in 1943, during World War II, with the stated purpose of “establishing criteria to serve as a target for appropriate nutrition.” According to “newer results,” it indicated the “recommended daily intakes for the major nutritional needs for people of different ages” (NRC, 1943).
The history of how the RDAs were developed is explained in-depth by the first chair of the Committee on Recommended Dietary Allowances (Roberts, 1958). Updates have been made to the original article.

Answer:
mass spectrometry-Components of the samples are compared to known molecular weights.
microcrystalline test-Samples are mixed with reagents and observed under a polarized microscope
spectroscopy-Samples are exposed to UV and IR rays and their absorbance is measured.
Color test-Samples are mixed with specific reagents to produce colors.
Mass spectroscopy employs the technique of measurement of mass to charge ratio in determining the molecular weight
Spectroscopy deals with the relationship between a matter and electromagnetic radiations.
