In the 1930’s‚ Richard Dogmagk experimented with a red dye called prontosil and found that it had strange healing effects‚ when he injected the dye into mice with severe streptococcus infections‚ they all survived. Dogmagk had discovered the one of the fist antibiotics‚ specifically the first Sulfa drug. When scientists isolated the active part of the prontosil molecule they discovered how it and all sulfa drugs work. Sulfa drugs contain a sulfur atom that has six total bonds (shared electrons)

Cinematography History Cinematography is an art form in the field of filmmaking. Although the exposing of images on light-sensitive elements dates to the early 19th century‚[4] motion pictures demanded a new form of photography and a new aesthetic.

The cameras were arranged along a track parallel to the horse’s‚ and each camera shutter was controlled

bacteria have a simpler cell wall‚ with a large amount of peptidoglycan. Peptidoglycan is a polymer composed of modified sugars cross-linked by short polypeptides. In effect‚ the cell wall traps the crystal violet in the cytoplasm‚ concealing the red dye safranin in gram staining experiment. Certain gram positive species have virulent strains that are resistant to one or more drugs. Gram negative bacteria on the other hand are composed of lipopolysaccharides (LPS)‚ porin channels‚ and murein lipoprotein

Mycobacterium). These organisms contain mycolic acid in their cell walls rather than peptidoglycan. The use of Acid alcohol produces the stain since it does not decolorize an acid-fast organism. The acidic dye‚ Carbol Fuchsin‚ is the primary stain to use in order to retrain the acid-fast organism’s cell wall. Next‚ the basic counterstain‚ Methylene blue‚ is added on to stain the rest of the organism with the expectation of the acid-fast bacterium. This will
