Problem: Genes with a most recent common ancestor, and thus a shared evolutionary ancestry, are known as homologs. These genes appear either from gene duplication within an organism's genome, where they are known as paralogous genes, or are the result of divergence of the genes after a speciation event, where they are known as orthologous genes,:7.6 and often perform the same or similar functions in related organisms. It is often assumed that the functions of orthologous genes are more similar than those of paralogous genes, although the difference is minimal.
What are genes with a most recent common ancestor called?
The answer is the following: homologs

Problem: The Estonian Academy of Sciences is the national academy of science. The strongest public non-profit research institute that carries out fundamental and applied research is the National Institute of Chemical Physics and Biophysics (NICPB; Estonian KBFI). The first computer centres were established in the late 1950s in Tartu and Tallinn. Estonian specialists contributed in the development of software engineering standards for ministries of the Soviet Union during the 1980s. As of 2011[update], Estonia spends around 2.38% of its GDP on Research and Development, compared to an EU average of around 2.0%.
What cities were the locations of the first computer centers?
The answer is the following: Tartu and Tallinn

Problem: In September 1939, Britain and the self-governing Dominions, but not Ireland, declared war on Nazi Germany. George VI and his wife resolved to stay in London, despite German bombing raids. They officially stayed in Buckingham Palace throughout the war, although they usually spent nights at Windsor Castle. The first German raid on London, on 7 September 1940, killed about one thousand civilians, mostly in the East End. On 13 September, the King and Queen narrowly avoided death when two German bombs exploded in a courtyard at Buckingham Palace while they were there. In defiance, the Queen famously declared: "I am glad we have been bombed. It makes me feel we can look the East End in the face". The royal family were portrayed as sharing the same dangers and deprivations as the rest of the country. They were subject to rationing restrictions, and U.S. First Lady Eleanor Roosevelt remarked on the rationed food served and the limited bathwater that was permitted during a stay at the unheated and boarded-up Palace. In August 1942, the King's brother, Prince George, Duke of Kent, was killed on active service.
How many people died on the first German raid on London?
The answer is the following: one thousand civilians

Problem: The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo 4-stage metamorphosis (see holometabolism). Insects that undergo 3-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. The higher level relationship of the Hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22–28 in). The most diverse insect groups appear to have coevolved with flowering plants.
What is the primary constraint on the physical growth of an insect?
The answer is the following:
inelastic exoskeleton
