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.
All other living things also grow or get bigger. A virus does nothing inside its protein coat; therefore it does not grow. But some scientists argue that a virus's growth occurs inside the host cell where parts of viruses are built during reproduction.Plants and animals react to the environment.iruses must have a host cell to live and reproduce. Outside of the host cell, viruses are pieces of genetic molecules that can do nothing by themselves. Viruses are right on the border between living and nonliving. Some biologists currently see the virus as a nonliving infectious particle.
