Yes, hookah can stain walls due to the smoke produced during use, which contains tar, nicotine, and other substances. Over time, these particles can adhere to surfaces, leading to discoloration. The extent of staining can depend on factors such as ventilation, frequency of use, and the type of tobacco used. Regular cleaning can help minimize the buildup and staining effects.
Yes, the Gram stain can be useful for distinguishing between yeasts as yeast cells typically stain purple (Gram-positive) due to their thick cell walls. This can help differentiate them from bacteria which can stain pink (Gram-negative). However, additional tests may be needed for accurate identification of different yeast species.
Gram stain is commonly used to distinguish differences between the cell walls of medically important bacteria. This technique categorizes bacteria into Gram-positive (purple) and Gram-negative (pink) based on their cell wall structure, aiding in identification and classification of bacteria in microbiology.
One common stain used for plant tissue is safranin, which is often used to stain plant cell walls and lignified tissues red. There are other stains like toluidine blue and crystal violet that are also commonly used for plant tissue staining.
Mycobacterium and Nocardia species are liable to stain positive with an acid-fast stain due to the high lipid content in their cell walls, specifically mycolic acids. This makes them resistant to decolorization with acid-alcohol during staining procedures, allowing them to retain the primary stain (carbolfuchsin) and appear red or pink under a microscope.
Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with. If the violet can be washed out and the counter stain (pink) is added, the bacteria are Gram-.
Yes, weed smoke can stain walls over time due to the residue it leaves behind.
yes

yes....
simple answer is NO
Walls are walls, wherever they are. - This problem depends on what the stain is and you haven't said. Possibly easiest to simply repaint the wall - first with a 'stain blocker' such as Zinnser Bull's Eye or Kilz Stain Blocker Primer. -These products work well and ANY paint can be applied over them. -(if the wall is papered, then you should remove paper first.)
The Gram stain is not effective on acid-fast bacteria because their cell walls have a waxy layer that prevents the stain from penetrating.

Hookah smoking is not safer than cigarette smoking. The tobacco is no less toxic in a hookah pipe, and the water in the hookah does not filter out the toxic ingredients in the tobacco smoke.
Bacteria are divided into two groups based on how their cell walls absorb the Gram stain. Gram-positive bacteria retain the stain due to their thick peptidoglycan cell wall, while Gram-negative bacteria do not retain the stain because of their thin peptidoglycan cell wall and an outer membrane.
Hookah is not a drug, it's a type of pipe.
