In a MerCruiser ignition system, the purple wire is typically connected to the positive post of the coil. This wire carries the voltage from the ignition switch to the coil, enabling it to generate a spark for the engine. It's important to ensure proper connections and functionality, as a faulty wire can lead to ignition problems. Always refer to the specific wiring diagram for your engine model for accurate information.

Do gram-positive cells carry a net positive charge?

Gram-positive does not refer to a positive charge, but to the purple color of the stain. Gram-negative bacteria do not retain the purple dye and are instead red in color.

What colors do gram-positive and gram-negative bacteria stain?

Gram-positive bacteria stain purple, while gram-negative bacteria stain pink or red. This staining is a result of differences in their cell walls' composition and structure. Gram-positive bacteria have a thick peptidoglycan layer that retains the purple crystal violet dye, while gram-negative bacteria have a thinner peptidoglycan layer covered by an outer membrane that doesn't retain the dye well.

On the basis of gram reaction only can you distinguish between staphylococcus and streptococcus?

If the Gram stain is properly done, and based on color alone: - you CANNOT distinguish between Staphylococcus (positive/purple) and Streptococcus (positive/purple) - you CAN distinguish between Staphylococcus (positive/purple) and Neisseria (negative/red) - you CANNOT distinguish between Escherichia (negative/red) and Proteus (negative/red) - you CAN distinguish between Escherichia (negative/red) and Bacillus (positive/purple) Gram positives will stain purple because of the retention of the dye (crystal violet) in their thick peptidoglycan cell walls. On the other hand, Gram negatives have a thin cell wall and cannot retain the purple stain, so when they are counterstained, they will appear red


Is S epidermidis gram negative or gram positive?
