Cultivation of bacteria is essential for the study of bacteria, usually in the development of vaccines for particular pathogens.
don't do it without adult supervision
95% of microbes can not be grown on cultured media so its highly unlikely that you would take a sample and all of the microorganisms grow. I had this same question in my lab manual and thats how my professor described it.
to kill contaminants like bacteria and fungi from laboratory
The importance of knowing the uses of the different apparatus is to protect it safely and to use it safely.
it is grown from bacteria
There are currently only a handful of labs that make lab grown *gem* quality diamonds. Gemesis and Apollo are two.If you are asking about lab grown diamonds that are of industrial quality (small, not pretty pieces) then there are lots including GE, Sumitomo and DeBeers (E6).I've attached links to a grower and a seller of lab grown diamonds for jewelry below.
I would put out fire safely in a science lab by spreading Carbon di oxide gas on the fire
no
No, it is a plant and can be grown.
procedures
Apparently, lab-grown diamonds and mined diamonds from the earth, when cut and polished are both weighed in carats. It is important, however, to document any lab-grown stone as such. Note that Gemological Institute of America certification for lab-grown stones will always note their origin and provide the four Cs, and apparently the European Gemological Laboratory can grade lab-grown stone. You can read more, below.
No. They need living cells or tissues to be grown.
In a lab. It isn't grown, it's a synthetic chemical.
Lab grown Moissanite Diamonds are as natural as diamonds mined from the earth. Lab grown Diamonds are Similar to World Mined Diamonds in Every Way, but they are Developed in a Lab. They have the same chemical, physical, and optical properties as mined Diamonds and show the same Fire, Scintillation, and Sparkle. Visit Here:- Nakshu Jewels
It can be produced by bacteria in a lab.
It wasn't invented on purpose. It was a Scottish guy that invented it and the story goes: he left a window in his lab opened and went on holiday, when he arrived back at the lab he noticed that the bacterium he had growing in his petree dishes had grown all over except in circles around a piece of mold or fungus or something that had blown into the lab through the window. He extracted the stuff that was in the circle that was clear of bacteria and worked out that the substance must either kill or hinder the growth of bacteria.
