A normal heart is made up of muscle tissue, specifically the cardiac muscles. A normal heart only needs the cells of the body that produces energy.
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.
