The slug is a derived unit of mass in a weight-based system of measures, most notably within the British Imperial measurement system and the United States customary measures system. Systems of measure either define mass and derive a force unit or define a base force and derive a mass unit [ 1 ] (cf. poundal , a derived unit of force in a mass ...
Yellow slugs, like the majority of other land slugs, use two pairs of tentacles on their heads to sense their environment. The upper pair, called optical tentacles, is used to sense light. The lower pair, oral tentacles, provide the slug's sense of smell. Both pairs can retract and extend themselves to avoid hazards, and, if lost to an accident ...
Arion hortensis, also known by its common name the "garden slug", "small striped slug" or "black field slug" is a species of small air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae, the roundback slugs.

Mass flow rate is defined by the limit [3] [4] ˙ = =, i.e., the flow of mass through a surface per time .. The overdot on ˙ is Newton's notation for a time derivative.Since mass is a scalar quantity, the mass flow rate (the time derivative of mass) is also a scalar quantity.
Arion is a genus of air-breathing land slugs in the family Arionidae, the roundback slugs.Most species of this Palearctic genus are native to the Iberian Peninsula. [2]Species can be difficult to distinguish from one another upon cursory examination, because individuals of a species can vary in color and there are few obvious differences between taxa. [3]
A similar system, termed British Engineering Units by Halliday and Resnick (1974), is a system that uses the slug as the unit of mass, and in which Newton's law retains the form F = ma. [5] Modern British engineering practice has used SI base units since at least the late 1970s.
A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
