What else can I help you with?
What would the slide look like under the microscope if methylene blue is used instead of nigrosin?
The stain would stain the cells rather than the background
Which is an example of a dye used in a simple stain?
Methylene blue
Is methylene blue a chromophore?
Nope - methylene blue is a stain. You need liquid indicator like phenolphthalein that responds to pH changes.
Can methylene blue be used in other food besides milk?
Yes, methylene blue can be used in many foods, as it in non-toxic to humans (though it can discolor urine). Methylene blue was used by Italian actor and gourmand, Ugo Tognazzi for his risotto alla parmigiana (risotto blu). He added methylene blue to the standard ingredients (butter, onions, Parmesan cheese, and white wine), turning it into a rather striking "blue risotto."
Which substance can a student use to make the nuclei more visible?
A student can use a stain called methylene blue to make nuclei more visible under a microscope. Methylene blue is commonly used in biology and histology to stain cells and highlight structures like nuclei.
Is it useful to stain the Elodea and Anabaena cells with methylene blue stain?
Staining Elodea and Anabaena cells with methylene blue can be useful in microscopy to enhance contrast and visualize cell structures more clearly. Methylene blue is commonly used as a general stain to highlight cellular components such as nuclei and cytoplasm. This staining technique can aid in identifying cellular organelles and structures during microscopic examination.
What is the function methylene blue solution in the preparation of cheek cells slide?
Methylene Blue, in this situation, is being used as a microscopy stain. Microscopy stains are used to allow for particular characteristics of cells to be observed in greater detail or to make them easier to see.
What is methylene blue use for when gram staining?
Methylene blue can be used to prepare slide for animal cells. For example, if you want to examine a piece of your cheek cell, you would take a piece of cotton wool and rub it on the inside of your cheek and the rub it on a microscope slide, the you add a little distilled water and then a drop of methylene blue. The final step you would take, is to cover the slide with a cover slip, then place it under the microscope.
Why is methylene blue used as an indicator of cell respiration?
because methylene blue turns colourless when it is reduced by hydrogen. during respiration hydrogen is produced and instead of reducing NAD, it reduces methylene blue and turns methylene blue colourless. if methylene blue goes from blue to colourless then this shows that the cell is respiring as it is producing a suffiecient amount of hydrogen to decolourise methylene blue
What would the slide look like under the microscope if methylene blue is used instead of nigrosin?

What can be used to substitute safranin?
methylene blue kot
What Slide mount is used for viewing an Elodea leaf?
A wet mount slide is typically used to view an Elodea leaf under a microscope. This type of slide allows the leaf to remain in a hydrated state, which is important for observing its cellular structure and processes.
Which is an example of a dye used in a simple stain?
Methylene blue
Which of the availble stain enhance your observation the most methylene blue or iodide?
Methylene blue would enhance your observation more than iodide staining. Methylene blue binds to nucleic acids and proteins, making them more visible under a microscope. Iodide staining is primarily used for visualizing lipids in samples such as plant tissues.
Is methylene blue a chromophore?
Nope - methylene blue is a stain. You need liquid indicator like phenolphthalein that responds to pH changes.

What color is methylene blue?
Methylene blue is a synthetic dye that appears as a dark blue or greenish-blue color in its solid form. It is commonly used in biological staining techniques and as a medication for certain medical conditions.
