Information: - The siphuncle is a strand of tissue passing longitudinally through the shell of a cephalopod mollusk. Only cephalopods with chambered shells have siphuncles, such as the extinct ammonites and belemnites, and the living nautiluses, cuttlefish, and "Spirula". In the case of the cuttlefish, the siphuncle is indistinct and connects all the small chambers of that animal's highly modified shell; in the other cephalopods it is thread-like and passes through small openings in the walls dividing the chambers. - Endocerida is an extinct nautiloid order, a group of cephalopods from the Lower Paleozoic with cone-like deposits in its siphuncle. - Clitendoceras is a member of the Endocerida from the Lower Ordovician (m-u Canadian) with an elongate shell with a slight downward, endogastric, curvature and a siphuncle that lies along the ventral margin. Common for endocerids, the chambers are short and the septa close spaced with sutures sloping forward across the back of the shell. Septal necks are short in the young, lengthening in the adult. Endocones are simple, but with the ventral side of the last formed projecting forward. The endosiphotube running down the middle is arched on top and somewhat flat on the lower side. - The Piloceratidae are a compressed , rapidly expanding , cyrtoconic brevicones with holochoanitic ventral siphuncles and simple endocones . Most likely evolved from Clitendoceras , a narrow , slightly endogastric genus intermediate in form between straight shelled Proendoceras and the bulkier Piloceratidae . Found in shallow carbonate marine sediments of Demingian through the Cassinian age , ( essentially Arenigian , = early Middle - Upper Canadian ) . Pilocerids split off from the Proterocameroceratidae very shortly after their inception and are the first family which the proterocamerocerids gave rise to . With the exception of Humeoceras , found in the middle Silurian , pilocerid genera are limited to the Lower Ordovician ( Canadian in North America ) . The general shape of the pilocerid shell precludes an ambush predator lying in wait on the sea floor , or a stealthful hunter drifting through the water . Rather , they probably crawled over the sea floor , head down with the shell off the bottom , searching for prey . Nothing is known of their soft part anatomy , other than what can be surmised from the fact they are cephalopods . They likely possessed tentacles of some sort , but were they numerous like those of modern Nautilus , limited to eight or ten as with octopus or squid , or of some other arrangement . Pilocerid genera include the strongly curved Piloceras , Bisonoceras with its hooked bison horn shape , nearly straight Allopiloceras , Dartonoceras , and internally complex Cassinoceras . Ecologically the Piloceratidae were replaced in the Middle Ordovician by the Cyrtendoceradae , which may have evolved early from the Endoceratidae rather than being direct pilocerid descendents . After reading the paragraphs above, we are interested in knowing the entity with which 'piloceratidae' exhibits the relationship of 'parent taxon'. Find the answer from the choices below. Choices: - endocerida - septa - spirula

Information: - Stand-up comedy is a comic style in which a comedian performs in front of a live audience, usually speaking directly to them. The performer is commonly known as a comic, stand-up comic, stand-up comedian, or simply a stand-up. In stand-up comedy, the comedian usually recites a grouping of humorous stories, jokes and one-liners typically called a monologue, routine, or act. Some stand-up comedians use props, music, or magic tricks to "enhance" their acts. Stand-up comedy is often performed in comedy clubs, bars and pubs, nightclubs, neo-burlesques, colleges and theatres. Outside of live performance, stand-up is often distributed commercially via television, DVD, CD and the internet. - A situation comedy, or sitcom, is a genre of comedy centered on a fixed set of characters who carry over from episode to episode. Sitcoms can be contrasted with sketch comedy where a troupe may use new characters in each sketch, and stand-up comedy where a comedian tells jokes and stories to an audience. Sitcoms originated in radio, but today are found mostly on television as one9 of its dominant narrative forms. This form can also include mockumentaries. - The Simpsons is an American animated sitcom created by Matt Groening for the Fox Broadcasting Company. The series is a satirical depiction of working-class life epitomized by the Simpson family, which consists of Homer, Marge, Bart, Lisa, and Maggie. The show is set in the fictional town of Springfield and parodies American culture, society, television, and the human condition. - Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. - Sketch comedy comprises a series of short comedy scenes or vignettes, called "sketches", commonly between one and ten minutes long. Such sketches are performed by a group of comic actors or comedians, either on stage or through an audio or visual medium such as radio and television. Often sketches are first improvised by the actors and written down based on the outcome of these improv sessions; however, such improvisation is not necessarily involved in sketch comedy. - Samuel Michael "Sam" Simon (June 6, 1955 March 8, 2015) was an American director, producer, writer, animal rights activist, boxing manager, tournament poker player, and philanthropist, most noted as co-developer of the television series "The Simpsons". - The George Carlin Show was an American sitcom that aired on the Fox network from January 1994 to July 1995 . It was created jointly by Sam Simon and the show 's namesake , comedian George Carlin .
