List 3 reasons why we would want to do a field test over a laboratory test.

What components make up BMI?

You correctly perform a Gram stain on a sample of bacteria by following these steps on your dried smear of cells on a glass slide: Addition of a few drops crystal violet for 1 minute; rinse Addition of a few drops Gram’s iodine for 1 minute; rinse Decolorization with alcohol/acetone mixture until clear but fewer than 12 seconds; rinse Addition of a few drops of safrinin for 1 minute; rinse When finished, you observe a mixture of purple and pink cocci.
