Ques: Information: - Bangiophyceae was a class of red algae ; it has since been merged with the Floridophyceae to form the Rhodophyceae . The Bangiophyceae , as defined traditionally , are paraphyletic . Their taxonomic identification has been difficult because of a lack of distinct morphological features , and the presumed morphological plasticity of the species . Molecular tools are required to elucidate the relationships within this assemblage . It is still used by some sources , and defined sensu stricto ( including Bangia and Porphyra but not the species included in Florideophyceae ) is considered a valid clade . - The red algae, or Rhodophyta (or ; from Ancient Greek: "rhodon", "rose" and "phyton", "plant"), are one of the oldest groups of eukaryotic algae. The Rhodophyta also contains one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and consist of mostly multicellular, marine algae, including many notable seaweeds. Approximately 5% of the red algae occur in freshwater environments. - Algae (singular "alga" ) is an informal term for a large, diverse group of photosynthetic organisms which are not necessarily closely related, and is thus polyphyletic. Included organisms range from unicellular genera, such as "Chlorella" and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50m in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, "Spirogyra" and the stoneworts. Given the information above, choose from the list below the object entity that exhibits the relation 'parent taxon' with the subject 'bangiophyceae'. Choices: - charophyta - chlorella - florideophyceae - rhodophyta
Ans: rhodophyta

Ques: Information: - Under the Whyte notation for the classification of steam locomotives, a locomotive has two leading wheels on one axle, usually in a bissel truck, ten coupled driving wheels on five axles, and four trailing wheels on two axles, usually in a bogie. These were referred to as the Texas type in most of the United States, the Colorado type on the Burlington Route and the Selkirk type in Canada. Overview. The Texas wheel arrangement originated and was principally used in the United States of America. The evolution of this locomotive type began as a Santa Fe type with a larger four-wheeled trailing truck that would allow an enlarged firebox. A subsequent development was as an elongated Berkshire type that required extra driving wheels to remain within axle load limits. Examples of both of these evolutionary progressions can be found. - On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. - A steam locomotive is a railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible materialusually coal/coke, wood, or oilto produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers). Both fuel and water supplies are carried with the locomotive, either on the locomotive itself or in wagons (tenders) pulled behind. The first steam locomotive, made by Richard Trevithick, first operated on 21 February 1804, three years after the road locomotive he made in 1801. The first practical steam locomotive was built in 1812-13 by John Blenkinsop. - Santa Fe 5017 is a 2 - 10 - 4 or '' Texas '' type steam locomotive built by the Baldwin Locomotive Works in 1944 for the Atchison , Topeka and Santa Fe Railway . - Richard Trevithick (13 April 1771 22 April 1833) was a British inventor and mining engineer from Cornwall, England. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He performed poorly in school, but went on to be an early pioneer of steam-powered road and rail transport. His most significant contribution was the development of the first high-pressure steam engine. He also built the first full-scale working railway steam locomotive. On 21 February 1804 the world's first locomotive-hauled railway journey took place as Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. - A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Given the information above, choose from the list below the object entity that exhibits the relation 'powerplant' with the subject 'santa fe 5017'. Choices: - steam engine - steam turbine
Ans:
steam engine
