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 naming organisms, biologists use binomial nomenclature, which Webster's Third International Dictionary defines as. a system of nomenclature in which each species of plant or animal receives a name of two terms of which the first identifies the genus to which it belongs and the second the species itself. For example, the house mouse has been assigned the two-part name Mus musculus, in which Mus is the genus name and musculus is the species name.
