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.
1 The two-word naming system that Linnaeus used to name various organisms is called binomial nomenclature (bi NOH mee ul Â· NOH mun klay chur). 2  This two-word name is an organismâs species. 3  The first word of the two-word name identifies the genus of the organism. 4  A genus is a group of similar species.
