WitrynaSpiders (Araneae) and scorpions (Scorpiones) are two orders of the class Arachnida, subphylum Chelicerata. In addition to ticks and mites (Acari), the Arachnida also include whip-scorpions (Thelyphonida), tailless whip-scorpions (Amblypygi), wind-scorpions or camel-spiders (Solifugae), false-scorpions (Pseudoscorpiones), harvestmen … WitrynaThe cells making up a hydra’s body are relatively simple. Hydra has two main body layers. The outer layer is the epidermis (like our skin) which can secret a protective layer (hydramacin) against bacterial infection. Respiration and excretion occur by diffusion through the surface of the epidermis. high traffic floor tape

Witrynadicted that the degree of tagmosis for higher taxa should reflect the complexity of their ecological role. Interactions in Cambrian ecosystems were almost certainly less complex than those of the present day (Valentine, 1973; Bergstrom, 1991). Moreover, Cambrian fossils are drawn from a limit WitrynaThe resulting "tagmosis value" reflects the functional differentiation of limb pairs to perform specific tasks and thus may ... Evolutionary longevity may depend on the adaptive type (e.g., trophic role, relation-ship to substrate, etc.) represented by the taxon and on the assortment of these adaptive types.
