Zero Point Foods. Instead of counting calories, Weight Watchers uses a point system to help control what you eat to lose weight. A mathematical equation focused on saturated fat, sugar, carb and calorie content is used to determine the point value for a food. Zero point foods are low in all these categories. All fresh fruit and most vegetables have zero points, with the exception of starchy vegetables such as corn or potatoes. In addition to helping fill you up without costing you any points, the list is used to help dieters on the Weight Watchers program make healthier food choices.
Two-Part Naming System. The scientific naming system that is used world-wide today was first devised by Swedish naturalist Carolus Linnaeus in 1737. He proposed a two-part naming system which classifies every living organism with a string of Latin and Greek identifiers. Full names are devised starting with kingdom and extending downward through phylum, subphylum, class, order, family, genus and species.
Until the 1750s,scientists named organisms however they wanted. However, in 1753, Swedish botanistCarolus Linnaeus introduced a system of taxonomy that standardized the way thatorganisms are named and classified.Linnaeusâ method of naming organisms, called binomial nomenclature, is still usedtoday.
