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.
In the hierarchical system developed by Linnaeus species are referred to by two different names. Historically, predecessors of Linnaeus referred to species in descriptive phrases, in Latin. Binominal consists of a genus and species name (epithet).1  Each species is placed into a genus.ogether with the presentation of the consistent binomial system of naming, Linnaeus also developed a system of organizing the diversity of life in a hierarchical classification. Latin was the important language of the time of Linnaeus and continues to be a critical language for international communication.
