A   X  is a reproduction of a technical drawing, an architectural plan, or an engineering design, using a contact print process on light-sensitive sheets. Introduced by Sir John Hershelin 1842,the process allowed rapid, and accurate, production of an unlimited number of copies. processing of X is based on a photosensitive ferric compound. The best known is a process using ammonium ferric citrate and potassium ferricyanide.The paper is impregnated with a solution of ammonium ferric citrate and dried. When the paper is illuminated, a photoreaction turns the trivalent ferric iron into divalent ferrous iron. The image is then developed using a solution of potassium ferricyanide forming insoluble ferroferricyanide prussian blue in color with the divalent iron. This process is known as cyanotype.

  X is an organic compound    with the molecular formula  C 10 H 14 O . Its name comes from the fact that its 2-dimensional molecular structu re   resembles a living being.It's  suffix is "-one" indicates that it is a ketone . The systematic name   of the molecule is 3,4,4,5-tetramethylcyclohexa-2,5-dienone ID X

Semelpary is a biology related word.The word semelparity was coined by evolutionary biologist Lamont Cole,and comes from the Latin  semel  'once, a single time' and  pario  'to beget'.A species is considered semelparous if it is characterized by a single reproductive episode before death.
