Question: Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties. For example, steel is stronger than iron, its primary element. The electrical and thermal conductivity of alloys is usually lower than that of the pure metals. The physical properties, such as density, reactivity, Young's modulus of an alloy may not differ greatly from those of its elements, but engineering properties such as tensile strength and shear strength may be substantially different from those of the constituent materials. This is sometimes a result of the sizes of the atoms in the alloy, because larger atoms exert a compressive force on neighboring atoms, and smaller atoms exert a tensile force on their neighbors, helping the alloy resist deformation. Sometimes alloys may exhibit marked differences in behavior even when small amounts of one element are present. For example, impurities in semiconducting ferromagnetic alloys lead to different properties, as first predicted by White, Hogan, Suhl, Tian Abrie and Nakamura. Some alloys are made by melting and mixing two or more metals. Bronze, an alloy of copper and tin, was the first alloy discovered, during the prehistoric period now known as the bronze age; it was harder than pure copper and originally used to make tools and weapons, but was later superseded by metals and alloys with better properties. In later times bronze has been used for ornaments, bells, statues, and bearings. Brass is an alloy made from copper and zinc.

Question: Reapportionment following the 2010 United States Census gave the state two more seats in the House of Representatives. The legislature's redistricting, announced in 2012, was quickly challenged in court, on the grounds that it had unfairly benefited Republican interests. In 2015, the Florida Supreme Court ruled on appeal that the congressional districts had to be redrawn because of the legislature's violation of the Fair District Amendments to the state constitution passed in 2010; it accepted a new map in early December 2015.

Question: The world's first Institute of Technology the Berg-Schola (Bergschule) established in Selmecbánya, Kingdom of Hungary by the Court Chamber of Vienna in 1735 providing Further education to train specialists of precious metal and copper mining. In 1762 the institute ranked up to be Academia providing Higher Education courses. After the Treaty of Trianon the institute had to be moved to Sopron.

Answer: Court Chamber of Vienna
Question: Grazing organisms may also kill their prey species, but this is seldom the case. While some herbivores like zooplankton live on unicellular phytoplankton and therefore, by the individualized nature of the organism, kill their prey, many only eat a small part of the plant. Grazing livestock may pull some grass out at the roots, but most is simply grazed upon, allowing the plant to regrow once again. Kelp is frequently grazed in subtidal kelp forests, but regrows at the base of the blade continuously to cope with browsing pressure. Animals may also be 'grazed' upon; female mosquitos land on hosts briefly to gain sufficient proteins for the development of their offspring. Starfish may be grazed on, being capable of regenerating lost arms.
Try to answer this question if possible: What does zooplankton need to get enough protein to help the development of?
Answer:
unanswerable
