How many colors make the color Violet?
Violet is a secondary color. Secondary colors are achieved by mixing two of the three primary colors in equal proportions. Violet is made by mixing Blue and Red, therefore the answer is two.
What is the definition of analogous colors?
Colors that are related to each other are analogous. They are neighbors on the color wheel and share a common color. For example, blue violet, violet, and red violet. they all contain red. The Violet (a secondary color) has been made by mixing red and blue (both primary colors). The blue-violet and red-violet (both tertiary colors) have been made by mixing the secondary color (Violet) with the primary color included in it's name. They are analogous, or relatives, because they all contain red. This holds true for any three colors on the color wheel which directly in contact with each other. See the related link for more on mixing colors.
What is the genre of the song violet hour by sea wolf?
"Violet Hour" by Sea Wolf is considered to be an alternative-rock song according to iTunes.
How do you prepare 1 percent gentian violet?
1) take 10gm of gentian violet. then add to them: 2) Alcohol 70% ( H2O).... to 1000 ml
What is analogous colors that is on the color wheel?
An analogous scheme in association with the use of the Colour wheel is the usage of adjacent colours. EG: Red, Red-violet and Violet.
Is anthrax gram positive or negative?
Anthrax is a gram-positive bacterium, meaning it retains the crystal violet stain in the Gram staining procedure.
What is crystal violet iodine complex?
Crystal violet iodine complex, also known as the Gram's iodine, is used in the Gram staining technique to differentiate between Gram-positive and Gram-negative bacteria. It works by forming a complex with the peptidoglycan layer of the bacterial cell wall, allowing for visualization under a microscope.
Why is Iodine used in Gram staining?
Iodine is used in Gram staining as a mordant, which helps to bind the crystal violet dye to the cell wall of bacteria. This mordant-iodine complex forms larger complexes with the crystal violet dye, making it difficult for the dye to be washed away during the decolorization step. This allows for differentiation of Gram-positive and Gram-negative bacteria based on their ability to retain the crystal violet dye.
Explain why crystal violet would not be useful in the negative stain technique?
Crystal violet is a basic dye, meaning it has a positive charge and stains negatively charged structures well. In the negative stain technique, the background is stained, leaving the specimen colorless. Using crystal violet would inadvertently stain the specimen, resulting in a false positive.
Function of Gram's iodine?
Gram's iodine is used in the Gram staining method to differentiate bacteria into two major groups: Gram-positive and Gram-negative. It functions by forming complexes with the crystal violet dye in the cell wall of the bacteria. This allows for the retention of the dye by Gram-positive bacteria, while it is washed off from Gram-negative bacteria.
What are the functionally analogous pair of stains?
Crystal violet and safranin are functionally analogous pair of stains in the Gram staining technique. Crystal violet stains gram-positive bacteria purple/blue, while safranin counterstains gram-negative bacteria pink/red.
Why is timing so critical when decolourizing in Gram staining?
Timing is critical when decolorizing in Gram staining because if the decolorizer is left on for too long, it can wash away the crystal violet stain from Gram-positive cells, leading to a false negative result. Conversely, if the decolorizer is not left on long enough, the crystal violet stain may not be fully removed from Gram-negative cells, leading to a false positive result. Timing ensures accurate differentiation between Gram-positive and Gram-negative bacteria.
What is positive staining?
cells which take up crystal violet stain and retain them because of smal pore size
Why gram staining classified as differential staining?
Differential staining is the procedure that are used to distinguish organism based on their staining properties. Use of gram stain divide bacteria into two classes - gram positive which retain crystal violet stain purple colour, gram negative which lose their crystal violet and give pink colour. By this method we can differentiate two different types of bacteria having different cell wall composition that is the reason gram staining used widely as differential staining

What color will gram stain positive turn into?
Gram-positive bacteria will retain the crystal violet dye during the gram staining process, appearing purple/blue under a microscope.
What is the staining process for separating bacteria?
One common staining process for separating bacteria is the Gram staining method. This involves applying crystal violet, iodine, alcohol, and safranin to the bacterial sample. Gram-positive bacteria will retain the crystal violet stain, appearing purple, while Gram-negative bacteria will not retain it and will appear pink after the safranin counterstain.
