What is the importance of iodine after primary stain?
Iodine is used after the primary stain in the Gram stain procedure to form a complex with the crystal violet dye, which helps to stabilize the dye within the bacterial cell wall. This step enhances the retention of the primary stain in Gram-positive bacteria.
What does lugol's iodine stain do to the activity of the cell?
I just did a lab in biology called "How Plant and Animal Cells Differ" and in the packet it had that question. The answer is: Lugol's iodine stain stops the activity of the cell. It kills whatever specimen it is staining.
How do remove stains from clay dirt?
To remove a stain left by clay dirt, first scrape off as much dirt as you can. Be careful not to spread the stain around as you do this. Pretreat the stain and wash it as you normally would. If the stain has not been removed after the washer, do not put it in the dryer and consider using bleach if it is safe for the fabric.
What is produced when iron-bearing silicate minerals in the desert landscape oxidize?
Iron-bearing silicate minerals in the desert landscape oxidize when exposed to air and moisture, producing iron oxide minerals such as hematite and limonite. These minerals give the soil a red or orange color commonly seen in desert regions.
How does hydrogen peroxide remove blood stain?
Hydrogen peroxide breaks down the components of blood stains through oxidation, which helps to lift the stain from the fabric. When hydrogen peroxide comes into contact with blood, it reacts with the enzymes and proteins in the blood to break them down, making it easier to clean the stain.
What causes white spots in stain?
generally bleach is what causes white stains in clothing.
Why does water cause a black stain in wood?
The stain could be caused by mold. The wood should be pressure washed and treated with a sealer. Another type of black stain in timber is caused by iron oxide. When the moisture in the timber has caused the iron in any fixings, such as nails, to rust and form ferric oxide. This is black, and this travels through the moisture in the timber causing patches of black staining.
What organism doesn't stain on a gram stain?
Mycoplasma is an example of an organism that does not stain on a Gram stain due to its lack of a cell wall. Mycoplasma is classified as a bacterium, but its unique cell wall composition causes it to not retain the crystal violet stain in the Gram staining process.
What was the sympathetic stain made of?
Ferrous (Iron II) and water mixed together. A simple solution of sodium carbonate (baking soda) and water could be used to bring out the invisible ink
What causes a stain?

Why is it not necessary for bleach to actually remove the substance that causes a stain?
Bleach removes the dye from what it comes into contact with. This means that when it comes into contact with a stain, it can take the pigments out of the stain. There may be other parts of the stain still there, but they are the same color as the rest of the article of clothing.

Which specific Mycobacterium organism was Ehrlich trying to stain when he developed the acid-fast stain?
Ehrlich was trying to stain Mycobacterium tuberculosis, the bacterium that causes tuberculosis. The acid-fast stain he developed allows for the visualization of the unique cell wall properties of this bacterium, which resists conventional staining methods.
What causes a camera to stop working?
