Please answer this: Information: - Mathematics (from Greek "mathma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics. - Geometry (from the ; "geo-" "earth", "-metron" "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the field of geometry is called a geometer. - In geometry , the ( angular ) defect ( or deficit or deficiency ) means the failure of some angles to add up to the expected amount of 360 or 180 , when such angles in the plane would . The opposite notion is the excess . Classically the defect arises in two ways : the defect of a vertex of a polyhedron ; the defect of a hyperbolic triangle ; and the excess also arises in two ways : the excess of a toroidal polyhedron . the excess of a spherical triangle ; In the plane , angles about a point add up to 360 , while interior angles in a triangle add up to 180 ( equivalently , exterior angles add up to 360 ) . However , on a convex polyhedron the angles at a vertex on average add up to less than 360 , on a spherical triangle the interior angles always add up to more than 180 ( the exterior angles add up to less than 360 ) , and the angles in a hyperbolic triangle always add up to less than 180 ( the exterior angles add up to more than 360 ) . In modern terms , the defect at a vertex or over a triangle ( with a minus ) is precisely the curvature at that point or the total ( integrated ) over the triangle , as established by the Gauss -- Bonnet theorem . - Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. What is the relationship between 'angular defect' and 'quantity'?

Q: Information: - Pupinidae is a taxonomic family of land snails with an operculum, terrestrial gastropod mollusks in the superfamily Cyclophoroidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). - Liarea is a genus of land snails with an operculum , terrestrial gastropod molluscs in the subfamily Liareinae . - A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus. - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs. - Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod molluscs. However, the common name "snail" is also applied to most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other molluscs that are not actually gastropods, such as the Monoplacophora, which superficially resemble small limpets, may also informally be referred to as "snails". - Liareinae is a taxonomic subfamily of small land snails, terrestrial pulmonate gastropod molluscs in the family Pupinidae. - In the context of human society, a family (from ) is a group of people affiliated either by consanguinity (by recognized birth), affinity (by marriage or any other relationship like siblings families etc..), or co-residence (as implied by the etymology of the English word "family") or some combination of these. Members of the immediate family include spouses, parents, brothers, sisters, sons, and/or daughters. Members of the extended family may include grandparents, aunts, uncles, cousins, nephews, nieces, and/or siblings-in-law. Sometimes these are also considered members of the immediate family, depending on an individual's specific relationship with them. What is the relationship between 'liarea' and 'pupinidae'?
