The way in which a ï¬rm assigns tasks to. workers yields the division of labour within the ï¬rm. In this setting, on the one hand, a. more extensive division of labour raises productivity because the returns to time spent. on tasks are generally greater to workers who concentrate on a narrower range of tasks.
Arachnids are a class (Arachnida) of joint-legged invertebrate animals , in the subphylum Chelicerata. All arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word á¼ÏÎ¬ÏÎ½Î· (arÃ¡chnÄ), meaning spider.
Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization.
