Information: - The P2 transport was a United States Maritime Commission design for a passenger ship which could be readily converted into a troop transport . Three variants of the design were built , the P2 - SE2 - R1 ( Admirals ) , P2 - S2 - R2 ( Generals ) , and P2 - SE2 - R3 ( Presidents ) . - The United States Maritime Commission (MARCOM) was an independent executive agency of the U.S. federal government that was created by the Merchant Marine Act of 1936, passed by Congress on June 29, 1936, and replaced the United States Shipping Board which had existed since World War I. It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to replace the World War I vintage vessels that comprised the bulk of the United States Merchant Marine, and to administer a subsidy system authorized by the Act to offset the cost differential between building in the U.S. and operating ships under the American flag. It also formed the United States Maritime Service for the training of seagoing ship's officers to man the new fleet. - The United States Merchant Marine refers to either United States civilian mariners, or to U.S. civilian and federally owned merchant vessels. Both the civilian mariners, and the merchant vessels, are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports cargo and passengers during peacetime; in times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military. Merchant Marine officers may also be commissioned as military officers by the Department of Defense. This is commonly achieved by commissioning unlimited tonnage Merchant Marine officers as Strategic Sealift Officers in the Naval Reserves. - The United States Maritime Service (USMS) was established in 1938 under the provisions of the Merchant Marine Act of 1936. The mission of the organization is to train people to become officers and crewmembers on merchant ships that form the United States Merchant Marine per Title 46 U.S. Code 51701. Heavily utilized during World War II, the USMS has since been largely dissolved and/or absorbed into other federal departments, but its commissioned officers continue to function as administrators and instructors at the United States Merchant Marine Academy and the several maritime academies.

Information: - Wiwaxia is a genus of soft-bodied animals that were covered in carbonaceous scales and spines. "Wiwaxia" fossils mainly isolated scales, but sometimes complete, articulated fossils are known from early Cambrian and middle Cambrian fossil deposits across the globe. The living animal would have measured up to 5cm (2inch) when fully grown, although a range of juvenile specimens are known, the smallest being long. - A Lagerstatte (from "Lager" 'storage, lair' "Statte" 'place'; plural "Lagerstatten") is a sedimentary deposit that exhibits extraordinary fossils with exceptional preservationsometimes including preserved soft tissues. These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying decomposition. "Lagerstatten" span geological time from the Neoproterozoic era to the present. Worldwide, some of the best examples of near-perfect fossilization are the Cambrian Maotianshan shales and Burgess Shale, the Devonian Hunsruck Slates and Gogo Formation, the Carboniferous Mazon Creek, the Jurassic Solnhofen limestone, and the Cretaceous Santana and Yixian formations. - Odontogriphus (literally "toothed riddle") is a genus of soft-bodied animals known from middle Cambrian Lagerstatte. Reaching as much as in length, "Odontogriphus" is a flat, oval bilaterian which apparently had a single muscular foot, and a "shell" on its back that was moderately rigid but of a material unsuited to fossilization. - Nostoc is a genus of cyanobacteria found in various environments that forms colonies composed of filaments of moniliform cells in a gelatinous sheath. - The Cambrian Period (or ) was the first geological period of the Paleozoic Era, of the Phanerozoic Eon. The Cambrian lasted 55.6 million years from the end of the preceding Ediacaran Period 541 million years ago (mya) to the beginning of the Ordovician Period mya. Its subdivisions, and its base, are somewhat in flux. The period was established (as Cambrian series) by Adam Sedgwick, who named it after Cambria, the Latinised form of "Cymru", the Welsh name for Wales, where Britain's Cambrian rocks are best exposed. The Cambrian is unique in its unusually high proportion of lagerstatte sedimentary deposits, sites of exceptional preservation where "soft" parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Cambrian biology surpasses that of some later periods. - Morania is a genus of cyanobacterium preserved as carbonaceous films in the Middle Cambrian Burgess Shale . it is present throughout the shale ; 2580 specimens of Morania are known from the Greater Phyllopod bed , where they comprise 4.90 % of the community . It is filamentous , forms sheets , and resembles the modern cyanobacterium Nostoc . It would have had a role in binding the sediment , and would have been a food source for such organisms as Odontogriphus and Wiwaxia . After reading the paragraphs above, we are interested in knowing the entity with which 'morania' exhibits the relationship of 'parent taxon'. Find the answer from the choices below. Choices: - animal - bacteria - cyanobacteria - mya - nostoc
(Answer)
cyanobacteria
