What is a sample of a colloid?
Milk is a common example of a colloid. The fat globules suspended in the liquid give it a cloudy or opaque appearance, characteristic of colloids.
What type of bond is necessary to obtain a positive Biuret result?
A positive Biuret test indicates the presence of peptide bonds, which are formed between amino acids in proteins. The Biuret reagent reacts with these peptide bonds, resulting in a color change that typically shifts to purple. This test is used to assess protein concentration in a sample.
What is single cell suspension?
Single cell suspension refers to a sample containing individual cells that have been separated from a tissue or culture, typically by enzymatic or mechanical digestion. This method allows for the study of individual cells in isolation and is commonly used in cell biology, flow cytometry, and single-cell sequencing techniques.
The origins of the mineral sample were?
The mineral sample is likely formed through a natural geological process such as crystallization from magma, precipitation from water solutions, or metamorphism of existing minerals. The specific origin can vary depending on the mineral's composition and the conditions under which it formed.
How are electrons removed from atoms to form ions in a mass spectrometer?
The vaporised sample passes into the ionisation chamber. The electrically heated metal coil gives off electrons which are attracted to the electron trap which is a positively charged plate. The particles in the sample (atoms or molecules) are therefore bombarded with a stream of electrons, and some of the collisions are energetic enough to knock one or more electrons out of the sample particles to make positive ions. Most of the positive ions formed will carry a charge of +1 because it is much more difficult to remove further electrons from an already positive ion. These positive ions are persuaded out into the rest of the machine by the ion repeller which is another metal plate carrying a slight positive charge.
Why is your blood sample cloudy or milky?
high triglycerides
How can you test food for fat?
For liquidsAdd 2cm(cube) of ethanol to a few drops of the unknown substance in a test tubeShake wellAdd 2cm(cube) of water to the test tubeA Positive result will result in a cloudy white suspension forming at the top of the solution.For solidsCut sample into a few pieces and place them in a test tubeAdd 2cm(cube) of ethanol and shake it thoroughly.Allow solid to settle and decant ethanol into another test tubeAdd 2 cm(cube) of water to the new test tubeA Positive result will result in a cloudy white suspension forming at the top of the solution.
Sample of suspension except milk?
Flour in water
Is the acid fast stain positive or negative in the sample?
The acid-fast stain is positive in the sample.
Is the acid fast stain result positive or negative for the sample?
The acid-fast stain result is positive for the sample.
Is the acid fast staining result positive or negative for the sample?
The acid-fast staining result for the sample is positive.
What is a sample of a colloid?
Milk is a common example of a colloid. The fat globules suspended in the liquid give it a cloudy or opaque appearance, characteristic of colloids.
What information would you need to know about a sample of air before you classify the sample as a solution suspension or a colloid?
the size of its largest particle
What element is responsible for the formation of cloudy solution in the silver nitrate test?
The formation of a cloudy solution in the silver nitrate test is a result of the precipitation of silver chloride when it reacts with chloride ions in the sample. Silver chloride is insoluble in water, leading to the formation of a cloudy appearance in the solution.
How can the presence of urea be determined in urine?
add phenophtalein to the urine sample....... if the result is white cloudy ppt. it containes urea.....
Can the sample mean in statistics be either positive or negative?
It can have either a negative or positive trend
I tested positive for a urine test will same sample test positive 19 days later?
Split sample drug test? It depends.If what you're asking is, "I was positive because I was doing drugs; are the drugs going to leave my sample after 19 days?" the answer is that you'll still be positive. They freeze the second part of your sample, so there's no way anything could get out of it--and the drug metabolites in the sample wouldn't leave the sample anyway.If, OTOH, you're asking "I got a false positive for grass because I was taking ibuprofen (Advil is famous for crossreacting with THC on dip-stick tests, which is one of the reasons I hate dip-stick tests); should I have the second sample tested?" go for it. If they test the second sample on GC/MS, which is the normal way for split-sample tests, it will be able to tell the difference between Advil and weed.
