the color of the food is recolored by the bile juice . bile juice absorbs the color pigments in turn produces yellow pigment that colors the material . \n10 points pls .

Yellow phlegm is normally a sign of an infection, or a case of the common cold. The initial state of the common flu when the phlegm is yet clear, is the most infectious period. When the phlegm turns into yellow, the body is already taking care of the infection\n\nOver-the-counter (OTC) drugs are medicines you can buy without a doctor’s prescription. OTC cough medicines are grouped into two types: antitussives and expectorants.\n\nAntitussives are cough suppressants. They relieve your cough by blocking the cough reflex. Dextromethorphan (some brand names: Triaminic Cold & Cough, Robitussin Maximum Strength, Vicks 44 Cough Relief) is a commonly used antitussive.\n\nExpectorants thin mucus. This may make coughing work better to clear the mucus from the airway. The only expectorant available in OTC products is guaifenesin (two brand names: Mucinex, Robitussin Expectorant).\n\nDextromethorphan and guaifenesin are sometimes combined with each other (one brand name: Robitussin DM). They are also available in combination with other drugs, such as pain relievers, decongestants or antihistamines. These combination products, such as multisymptom cold medicines, are meant to treat many symptoms at once. However, if your main symptom is cough, be careful of the drying effect of antihistamines and decongestants in combination medicines. This effect can make mucus thicker and harder to clear from the airways, which can make a cough worse.

I like the answer above for the first part of your question.\n\nA "trace colorant" would be a much smaller quantity of pigment -- often too small to be noticeable to the naked eye -- mixed in to a large bulk of material to provide some kind of marker that someone could use to trace the source of the pigment in the end product.  They might also cause VERY subtle differences in the pigmentation.\n\n"Tracers" or "taggants" enable companies to detect if someone has stolen their formula for a specific product.  They also allow law enforcement professionals to determine the source of a material -- forensic science does a lot of that sort of investigation to track down perpetrators of crimes.

When the bilirubin level gets high enough, the yellow color shows up in most visible areas--skin, urine, mucus membranes, etc; it's not just the sclera that turns yellow.

Well I experienced that it secreted something that glowed white in blacklight... but could be some perfume etc. too...\n\nskin can corrode metal... maybe because it secretes acids. I do not now how organic acids interfere with fabric colours, especially nonpermanent ones...

Yes. It means your liver is working very well to clear your blood of toxins.\n\nHigh bilirubin levels lead to a yellow skin and eyes and is called jaundice.

Since phenol is a (very) weak acid, it might be possible to make a quantitative measurement by titration of phenol solution with a standard solution of alkali using phenolphthalein indicator.\nAnother possibility is to make use of the fact that phenol reacts readily with bromine to form tribromophenol. This would involve a rather complicated process:\n1. Add the phenol to a measured excess of bromine solution;\n2. Then add the solution with the excess bromine to potassium iodide solution (making sure that there is more than enough KI); this produces an equal amount of iodine to the excess bromine.\n3. Titrate the iodine with standard sodium thiosulphate solution (starch indicator).

Many antiperspirants actually cause those stains.  The ingredient that stops sweating can damage clothing in this way, so it's a catch-22.

A densitometer works by scaning a stained electrophoresis agar. A light is passed through the plate and picked by a detector.  The light path is interupted by the stain and that creates a "blip" on the detector. The thicker the stained area, the bigger the blip and vice versa.  The detector then processes the light and blips to give a read out that looks like a bumpy line on a graph.  It allows you to determine the quantity of protein,or whatever your phoresing, to be determined.

Yes. It produces a bright yellow precipate:\nAgNO3 (aq) + KI (aq) → KNO3 (aq) + AgI (ppt)

Phyto means plant. Phytochemical screening means that you are screening chemicals found in a plant or from a plant

I haven't heard of it. My attitude toward it, however, is to find out WHAT the actual tests consisted of. Though people test products all the time, it does not mean that they tested in a way that could possibly be accurate.

The Phenol Coefficient test compares the potency of a disinfectant with that of phenol. A series of dilutions of phenol and the experimental disinfectant are inoculated with the test bacteria Salmonella typhi and Staphylococcus aureus, then placed in a 20 or 37 degree water bath. The highest dilution that kills the bacteria after 10 minutes exposure, \nbut not after 5 minutes are used to calculate the phenol coefficient.\n\nThe higher the phenol coefficient value, the more effective the disinfectant. A value greater than 1 means that the disinfectant is more effective than phenol.\n\nIts advantage is its ease of use.\n\nHowever, the EPA no longer recognizes a product's phenol coefficient as confirmation of its disinfecting capabilities since some products with high phenol coefficients were ineffective when used in the presence of certain organic matter and products with low phenol coefficients can be effective under \nactual use conditions.

maybe yellow jaundice hence yellow

Yes it is testable. And there are colorblind people who do not see some colors at all. Other than that there are lots of variation on how well each person can detect different variations of a color. Woman generally can detect slight changes in a color better than me. ( this is proven not a generalization). Best way to answer your question is by comparing it to singing. There are mute people who can not sing. Everyone else can sing but lots of variation in how well. Same with color recognition.
