Backflow is an unwanted reversal of water flow caused by a sudden drop or complete loss in water pressure. Instead of pushing water out of the plumbing fixture, the drop in water pressure sucks water back into the public water system, possibly contaminating the system where it connects to non-potable water.
In food science and in many informal contexts, the term carbohydrate often means any food that is particularly rich in the complex carbohydrate starch (such as cereals, bread and pasta) or simple carbohydrates, such as sugar (found in candy, jams, and desserts).ollowing this definition, some chemists considered formaldehyde (CH 2 O) to be the simplest carbohydrate, while others claimed that title for glycolaldehyde. Today the term is generally understood in the biochemistry sense, which excludes compounds with only one or two carbons.
