Venom types. Among the major classes of toxin in venoms are: Venom is widely distributed taxonomically, being found in both invertebrates and vertebrates; in aquatic and terrestrial animals; and among both predators and prey. The major groups of venomous animals are described below. Venomous arthropods include spiders, which use fangs — part of their chelicerae — to inject venom; and centipedes, which use forcipules — modified legs — to deliver venom; along with scorpions and stinging insects, which inject venom with a sting. In insects such as bees and wasps, the stinger is a modified egg-laying device — the ovipositor. In
Spaghetti sort Spaghetti sort Spaghetti sort is a linear-time, analog algorithm for sorting a sequence of items, introduced by Alexander Dewdney in his "Scientific American" column. This algorithm sorts a sequence of items requiring O("n") stack space in a stable manner. It requires a parallel processor. For simplicity, assume we are sorting a list of natural numbers. The sorting method is illustrated using uncooked rods of spaghetti: Preparing the "n" rods of spaghetti takes linear time. Lowering the rods on the table takes constant time, O("1"). This is possible because the hand, the spaghetti rods and the table work as a fully
