hair usually grows about 1/2 an inch per month. And grows about 6 inches every year. it depends how old u are. for example, a 40 year olds hair might not grow as fast as a 14 â¦ year old, because as you get older, cells divide less frequently, thus making hair grow slower.f a Black woman has very short to medium-short hair perhaps about two years with of course proper Hair Care, Exercise, using very little heat and Diet. WORDS OF ENCOURAGEMENT: Ladies, please know that it is possible to grow healthy shoulder-length hair if you are Black. Ciao!
The oxidase test is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain. (note: All bacteria that are oxidase positive are aerobic, and can use oxygen as a terminal electron acceptor in respiration.
TMPD. The oxidase test is a test used in microbiology to determine if a bacterium produces certain cytochrome c oxidases. It uses disks impregnated with a reagent such as N,N,Nâ²,Nâ²-tetramethyl-p-phenylenediamine (TMPD) or N,N-dimethyl-p -phenylenediamine (DMPD), which is also a redox indicator.he reagent is a dark-blue to maroon color when oxidized, and colorless when reduced. Oxidase-positive bacteria possess cytochrome oxidase or indophenol oxidase (an iron-containing hemoprotein). These both catalyze the transport of electrons from donor compounds (NADH) to electron acceptors (usually oxygen).
