QUES: Aside from water, wood has three main components. Cellulose, a crystalline polymer derived from glucose, constitutes about 4143%. Next in abundance is hemicellulose, which is around 20% in deciduous trees but near 30% in conifers. It is mainly five-carbon sugars that are linked in an irregular manner, in contrast to the cellulose. Lignin is the third component at around 27% in coniferous wood vs. 23% in deciduous trees. Lignin confers the hydrophobic properties reflecting the fact that it is based on aromatic rings. These three components are interwoven, and direct covalent linkages exist between the lignin and the hemicellulose. A major focus of the paper industry is the separation of the lignin from the cellulose, from which paper is made.
What's the name for the crystalline polymer derived from glucose?

ANS: Cellulose

QUES: Spielberg served as an uncredited executive producer on The Haunting, The Prince of Egypt, Just Like Heaven, Shrek, Road to Perdition, and Evolution. He served as an executive producer for the 1997 film Men in Black, and its sequels, Men in Black II and Men in Black III. In 2005, he served as a producer of Memoirs of a Geisha, an adaptation of the novel by Arthur Golden, a film to which he was previously attached as director. In 2006, Spielberg co-executive produced with famed filmmaker Robert Zemeckis a CGI children's film called Monster House, marking their eighth collaboration since 1990's Back to the Future Part III. He also teamed with Clint Eastwood for the first time in their careers, co-producing Eastwood's Flags of Our Fathers and Letters from Iwo Jima with Robert Lorenz and Eastwood himself. He earned his twelfth Academy Award nomination for the latter film as it was nominated for Best Picture. Spielberg served as executive producer for Disturbia and the Transformers live action film with Brian Goldner, an employee of Hasbro. The film was directed by Michael Bay and written by Roberto Orci and Alex Kurtzman, and Spielberg continued to collaborate on the sequels, Transformers: Revenge of the Fallen and Transformers: Dark of the Moon. In 2011, he produced the J. J. Abrams science fiction thriller film Super 8 for Paramount Pictures.
What film did Spielberg first collaborate with Zemeckis on?

ANS: Back to the Future Part III

QUES: A team led by Enrico Fermi in 1934 observed that bombarding uranium with neutrons produces the emission of beta rays (electrons or positrons from the elements produced; see beta particle). The fission products were at first mistaken for new elements of atomic numbers 93 and 94, which the Dean of the Faculty of Rome, Orso Mario Corbino, christened ausonium and hesperium, respectively. The experiments leading to the discovery of uranium's ability to fission (break apart) into lighter elements and release binding energy were conducted by Otto Hahn and Fritz Strassmann in Hahn's laboratory in Berlin. Lise Meitner and her nephew, the physicist Otto Robert Frisch, published the physical explanation in February 1939 and named the process "nuclear fission". Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction. Confirmation of this hypothesis came in 1939, and later work found that on average about 2.5 neutrons are released by each fission of the rare uranium isotope uranium-235. Further work found that the far more common uranium-238 isotope can be transmuted into plutonium, which, like uranium-235, is also fissile by thermal neutrons. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power.
Who led the team that discovered that bombarding uranium with neutrons created beta ray emissions?

ANS: Enrico Fermi

QUES: The central part of the Sahara is hyperarid, with little to no vegetation. The northern and southern reaches of the desert, along with the highlands, have areas of sparse grassland and desert shrub, with trees and taller shrubs in wadis where moisture collects. In the central, hyperarid part, there are many subdivisions of the great desert such as the Tanezrouft, the Tenere, the Libyan Desert, the Eastern Desert, the Nubian Desert and others. These absolute desert regions are characterized by their extreme aridity, and some years can pass without any rainfall.
Where are grasslands and shrubs frequently found in abundance?
