Polyploid cells and organisms are those containing more than two paired (homologous) sets of chromosomes. Most species whose cells have nuclei (Eukaryotes) are diploid, meaning they have two sets of chromosomes—one set inherited from each parent.
 However, polyploidy is found in some organisms and is especially common in plants.
 In addition, polyploidy occurs in some tissues of animals that are otherwise diploid, such as human muscle tissues.
 This is known as endopolyploidy.
 Species whose cells do not have nuclei, that is, Prokaryotes, may be polyploid organisms, as seen in the large bacterium "Epulopiscium fishelsoni" .
 Hence ploidy is defined with respect to a cell.
 Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis.
 A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid.
 Male bees and other Hymenoptera, for example, are monoploid.
 Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations.
 The gametophyte generation is haploid, and produces gametes by mitosis, the sporophyte generation is diploid and produces spores by meiosis.
Painless, also known under its original title of Insensibles, is a 2012 fantasy horror film and the feature film directorial debut of Juan Carlos Medina.

 "Painless" is set in Catalonia and follows two different story lines, one set during the Spanish Civil War and one set in the modern day.

Runcorn is a small industrial town in Halton, Cheshire, England, on the south bank of the River Mersey where it narrows at Runcorn Gap.
 In the town are the 61 buildings that are recorded in the National Heritage List for England as designated listed buildings in the current urban area of Runcorn, including the districts of Runcorn, Halton, Weston, Weston Point, and Norton.
 Two of these are classified as being in Grade I, nine in Grade II*, and fifty in Grade II.
 In the United Kingdom, the term "listed building" refers to a building or other structure officially designated as being of special architectural, historical or cultural significance.
 These buildings are in three grades: Grade I consists of buildings of outstanding architectural or historical interest; Grade II* includes particularly significant buildings of more than local interest; Grade II consists of buildings of special architectural or historical interest.
 Buildings in England are listed by the Secretary of State for Culture, Media and Sport on recommendations provided by English Heritage, which also determines the grading.
 The listed buildings are concentrated in Halton, which has 20, and Runcorn Town Centre, which has 16.
