Bratwurst (German: [ËbÊaËtvÊÉÌ¯st] ( listen)) is a type of German sausage made from veal, pork or beef. The name is derived from the Old High German BrÃ¤twurst, from brÃ¤t-, finely chopped meat, and Wurst, sausage, although in modern German it is often associated with the verb braten, to pan fry or roast.
Cold viruses have been shown to survive on indoor surfaces for approximately seven days. Flu viruses, however, are active for only 24 hours. All viruses have the potential to live on hard surfaces, such as metal and plastic, longer than on fabrics and other soft surfaces. In fact, infectious flu viruses can survive on tissues for only 15 minutes. Viruses tend to also live longer in areas with lower temperatures, low humidity, and low sunlight.
Viruses. A virus is a small amount of genetic material inside a viral coat (shell). Viruses are in any area where there are cells that can be infected by them. They exist to reproduce by taking over specific suitable host cells. It deposits its genetic code into the cell and then uses the cells ability to reproduce.icrobes, short for micro-organisms, are single-cell life forms that can only be seen through a microscope. Microbes are everywhere. Some cause disease while others keep people healthy. They grow on everything and they are so small you don't even notice they are there.
