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.
The clear oxidase reagent turns blue when cytochrome oxidase adds electrons to the chemical instead of to oxygen, as it normally does. Development of the blue color is positive for presence of the enzyme cytochrome oxidase. The color change does not occur in a negative test.Because of the expense and instability of oxidase reagent, this test is rarely performed in that manner.he clear oxidase reagent turns blue when cytochrome oxidase adds electrons to the chemical instead of to oxygen, as it normally does.
