What does a really faint blue negative line mean on an ept?
your pregnant!!!!!!!!!!!!!!!!!!!!!!!
Bag contains 5 blue blocks and 3 red blocks and 2 yellow blocks so what is the probability that someone will draw a red block and replace it and then a draw a blue block at random?
The probability of drawing a particular color is the number of blocks that color, over the total number of blocks. Since these are disjoint events, the solution is the product of the two probabilities of the draws. So: P(red, blue) = P(red) * P(blue) = (3/10) * (5/10) = 15/100 or 3/20
What is a BLUE rectangle?
A rectangle that is colored blue.
How many shades of blue are there?
There are an infinite number of possible shades. Each shade of blue can be modified slightly by adding a new colour, the possibilities are endless. As far as we know, there are more than fifty thousand shades of blue. Air Force Blue, Celeste, Egyptian blue, Maya Blue, Royal Blue, and Ultramarine are a few.
What colour will you be able to pick out of 1 red marble 2 blue marbles 2 green marbles and 3 yellow marble?
Red, blue, green or yellow.Red, blue, green or yellow.Red, blue, green or yellow.Red, blue, green or yellow.
What is the function of methylene blue solution on polluted water samples?
Polluted water sample will decolorize the methylene blue solution faster than a pure water sample.
What ingredients of EMB agar inhibit the growth of gram positive organisms?
Eosin and methylene blue dyes present in EMB (Eosin Methylene Blue) agar inhibit the growth of gram-positive organisms by interfering with their ability to take up nutrients and causing damage to their cell walls. This makes the medium selective for gram-negative bacteria, allowing them to grow while inhibiting the growth of gram-positive bacteria.
Will staph grow on EMB agar?
Staphylococcus bacteria typically do not grow well on Eosin Methylene Blue (EMB) agar. EMB agar is selective for gram-negative bacteria, particularly Enterobacteriaceae, and contains dyes that inhibit the growth of gram-positive bacteria like Staphylococcus.
Is it possible to substitute methylene blue for nigrosin in the negative stain?
no
What are the EMB test results for Staphylococcus epidermidis?
The Eosine Methylene Blue test is selective for only gram-negative bacteria. It is possible for gram-positive bacteria to grow, but it would barely grow. Staphylococcus are gram-positive spherical bacteria. So it would not grow on the Eosine methylene Blue Agar.
How do you make sugar crystals that are blue?
Adding methylene blue to sugar water solution.
What is the behavior of methylene blue towards the animal charcoal?
Methylene blue adsorbs onto the surface of animal charcoal through hydrophobic interactions and van der Waals forces. This adsorption process removes methylene blue molecules from solution, effectively purifying or decolorizing it.
What is the function on bile in Eosin Methylene Blue agar?
Bile salts in Eosin Methylene Blue agar inhibit the growth of Gram-positive bacteria, allowing for the selective growth of Gram-negative bacteria. This helps in the detection and differentiation of organisms based on their ability to ferment lactose and produce acid.
What ingridient makes EMB to be selective?
Eosin methylene blue (EMB) agar is selective due to the presence of dyes eosin Y and methylene blue, which inhibit the growth of Gram-positive bacteria. This allows for the selective isolation of Gram-negative bacteria, particularly coliforms.
Would methylene blue stain be substituted for safranin as the counter stain in this procedure?
Methylene blue is a stain used in microbiology. The dye attaches to the object, which allows what would normally be fairly see-through to be visible to the microscope.
What is the substances in a living cell that has same function as methylene blue?
NADH
How do you make methylene blue solution?
To make a methylene blue solution, you can dissolve methylene blue powder in water at a desired concentration. The typical concentrations range from 0.1% to 1%. Make sure to use proper safety precautions, such as wearing gloves and protective eyewear, as methylene blue can stain skin and clothing.
