QUES: In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. As these two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes.
What is the action of the food morving down the esophagus into the stomach called?

ANS: peristalsis

QUES: Bond travels to Austria to find White, who is dying of thallium poisoning. He admits to growing disenchanted with Quantum and tells Bond to find and protect his daughter, Dr. Madeline Swann, who will take him to L'Américain; this will in turn lead him to Spectre. White then commits suicide. Bond locates Swann at the Hoffler Klinik, but she is abducted by Hinx. Bond rescues her and the two meet Q, who discovers that Sciarra's ring links Oberhauser to Bond's previous missions, identifying Le Chiffre, Dominic Greene and Raoul Silva as Spectre agents. Swann reveals that L'Américain is a hotel in Tangier.
Who travels to Australia to find Mr. White?

ANS: unanswerable

QUES: Anthropologists believe the most significant benefit would have been the use of dogs' robust sense of smell to assist with the hunt. The relationship between the presence of a dog and success in the hunt is often mentioned as a primary reason for the domestication of the wolf, and a 2004 study of hunter groups with and without a dog gives quantitative support to the hypothesis that the benefits of cooperative hunting was an important factor in wolf domestication.
The successful mixing of dogs with hunting is often given as a primary reason for what?

ANS: the domestication of the wolf

QUES: The Russians sent a fleet to Sinop in northern Anatolia. In the Battle of Sinop on 30 November 1853 they destroyed a patrol squadron of Ottoman frigates and corvettes while they were anchored in port. Public opinion in the UK and France was outraged and demanded war. Sinop provided the United Kingdom and France with the casus belli ("cause for war") for declaring war against Russia. On 28 March 1854, after Russia ignored an Anglo-French ultimatum to withdraw from the Danubian Principalities, the UK and France formally declared war.
What did Battle of Sinop provide for France and the U.K?

ANS:
cause for war
