What principle is the microscopic method based on?
The microscopic method is based on the principle of using a microscope to magnify and observe tiny structures or particles that are not visible to the naked eye. This approach allows for detailed examination and analysis of the characteristics of the specimens being studied.
What is the RICE principle?
The RICE principle is a method used for treating minor injuries such as sprains, strains, and bruises. It stands for Rest, Ice, Compression, and Elevation, and it helps reduce pain and swelling, promote healing, and prevent further injury.
What would happen if you dropped the object into the beaker while using the Archimedes' Principle method instead of submerging the object?
If you dropped the object into the beaker instead of submerging it, you would not be able to accurately measure the volume of the displaced water. The Archimedes' Principle method relies on the accurate measurement of the volume of water displaced by the object when it is fully submerged to determine its density. Dropping the object instead would introduce inaccuracies into the calculation.
What did Archimedes have to do with matter?
Archimedes made significant contributions to the understanding of the behavior of matter. He developed the principle of buoyancy, known as Archimedes' principle, which explains why objects float or sink in a fluid. He also worked on the concept of density and developed methods to determine the volume of irregularly shaped objects.
What is the method used to find out the volume of an irregular solid?
One method to find the volume of an irregular solid is by using the water displacement method. This involves submerging the solid in a known volume of water and measuring the increase in water level, which corresponds to the volume of the solid.
What assay used to measure invertase actiivity?
The most common assay used to measure invertase activity is the DNS method, which involves measuring the release of reducing sugars from sucrose using dinitrosalicylic acid. This assay is based on the colorimetric detection of reducing sugars, which allows for the quantification of enzyme activity. Other methods include the Nelson-Somogyi method and the Nelson-Somogyi 3,5-dinitrosalicylic acid method.
What is the principle involved in the brine floatation method?
the principle of this test are used the method of a qualitative test for the detection of nematode and cestode eggs and coccidia oocysts in the faeces.
How do you measure cellulase activity?
Cellulase activity is typically measured by quantifying the amount of reducing sugars released from a cellulose substrate, such as carboxymethyl cellulose (CMC), using a colorimetric assay like the dinitrosalicylic acid (DNS) method. Alternatively, enzyme activity can also be assessed by monitoring the decrease in substrate concentration over time using techniques like HPLC or spectrophotometry.
Differentiate absorption method from colorimetric method?
Absorption method measures the amount of light absorbed by a sample at a specific wavelength, and is used to quantify the concentration of a substance. Colorimetric method utilizes color changes to detect the presence or concentration of a substance, often involving a chemical reaction that produces a color change.
Why we need colorimetric method in thermodynamics?
a proper question would be: Why do we need a calorimetric method in thermodynamics ?Then the answer would be: to measure the heat-capacity.
What is the principle of the cyanmethemoglobin method?
Colorimetric method where blood is mixed with solution containing potassium ferricyanide and potassium cyanide. Potassium ferricyanide oxidizes iron to form methemoglobin and potassium cyanide then combines with methemoglobin to form cyanmethemoglobin.
Why is electrometric method of pH determination more accurate than colorometric method?
The electrometric method of pH determination provides a single value dependent on the concentration of hydrogen ions in the aqueous solution being tested. The colorimetric method of pH determination uses acid-base indicators to provide a range of values for a solution's pH, and is therefore less accurate than the electrometric method.
What is fiske subbaRow procedure?
It's method of determining the inorganic phosphate content in urine or blood, etc. It is a colorimetric assay.
Which are the Methods for hemoglobin estimation?
Hemoglobin estimation is the measuring of hemoglobin levels that are broken into three categories. Visual methods are Sahil, Dares, Hadens, Wintrobes, Haldanes, Tallquists method. Second to consider are the gasometric method, single to the Van Slyke method. Lastly the spectrophotometric method oxyhemoglo, and the cyanmethemoblobin method.
How do you determine the colorimetric estimation of unknown copper sulphate concentration in solution?
To determine the colorimetric estimation of unknown copper sulfate concentration in solution, you can use a colorimetric method such as a complexation reaction with a specific reagent that forms a colored complex with copper ions. By measuring the absorbance of this colored complex at a specific wavelength using a colorimeter, you can correlate the absorbance values to known copper sulfate concentrations to determine the concentration of the unknown solution. Calibration curve plotting absorbance against known concentrations is commonly used in colorimetric estimations.
Which is more accurate to measure density Archimedes principle or water displacement method?
They are both the same. displacement method is another name for Archimedes' principle
What is fiske-subbaRow procedure?
The Fiske-subbaRow procedure is a method used in biochemistry to determine the protein concentration in a sample based on colorimetric analysis. It involves reacting protein samples with a reagent containing copper ions, forming a colored complex that can be measured spectrophotometrically to estimate protein concentration. The method is named after the scientists who developed it: Oliver H. Lowry, Nathan J. Rosebrough, Lewis A. Farr, and Rose E. Randall.
