Within small bodies, bees separate diffusing substances in an open cavity assisted by locomotion and the beat of the heart. The open arthropod circulation, however, is most efficient when shrunk until its large three-dimensional volume of blood turns into a two-dimensional film of fluid covering only the internal surfaces. This transformation increases the chances to near-certainty that molecules can diffuse from one point to another without getting lost.The Incredible ShrBeesPhysiologySize judgmentElectronic books.BeesPhysiology.Size judgment.573.1/15799Lawry James V957291MiAaPQMiAaPQMiAaPQBOOK9910453660303321The incredible shrinking bee2168449UNINA
