Gram Staining:
- Gram staining is a staining techniques used for the identification of bacteria in microbiological studies.
- Gram staining uses crystal violet as the primary stain. It complexes with the peptidoglycan cell wall of Gram positive bacteria giving them a purple color.
- An iodine mordant is also used that forms a crystal violet-iodine complex that fixes the crystal violet dye to the cell wall. This prevents the Gram positive cell walls from being decolorized by the application of alcohol.
- A counter stain, safranin is then applied that stains Gram negative bacteria pink.

From the question given above,
A snickers® candy bar contains
280 calories. Fat content = 120 calories
1 calorie = 4.184 j
120 calories = 120 x 4,184 =
502.08j = 5.0 x 10² KJ
The energy of the fat content is 5.0
x 10² KJ.
