Question: Different phases of digestion take place including: the cephalic phase , gastric phase, and intestinal phase. The cephalic phase occurs at the sight, thought and smell of food, which stimulate the cerebral cortex. Taste and smell stimuli are sent to the hypothalamus and medulla oblongata. After this it is routed through the vagus nerve and release of acetylcholine. Gastric secretion at this phase rises to 40% of maximum rate. Acidity in the stomach is not buffered by food at this point and thus acts to inhibit parietal (secretes acid) and G cell (secretes gastrin) activity via D cell secretion of somatostatin. The gastric phase takes 3 to 4 hours. It is stimulated by distension of the stomach, presence of food in stomach and decrease in pH. Distention activates long and myenteric reflexes. This activates the release of acetylcholine, which stimulates the release of more gastric juices. As protein enters the stomach, it binds to hydrogen ions, which raises the pH of the stomach. Inhibition of gastrin and gastric acid secretion is lifted. This triggers G cells to release gastrin, which in turn stimulates parietal cells to secrete gastric acid. Gastric acid is about 0.5% hydrochloric acid (HCl), which lowers the pH to the desired pH of 1-3. Acid release is also triggered by acetylcholine and histamine. The intestinal phase has two parts, the excitatory and the inhibitory. Partially digested food fills the duodenum. This triggers intestinal gastrin to be released. Enterogastric reflex inhibits vagal nuclei, activating sympathetic fibers causing the pyloric sphincter to tighten to prevent more food from entering, and inhibits local reflexes.

Answer: at the sight, thought and smell of food, which stimulate the cerebral cortex
Question: At about the same time, Charles Coffin, leading the Thomson-Houston Electric Company, acquired a number of competitors and gained access to their key patents. General Electric was formed through the 1892 merger of Edison General Electric Company of Schenectady, New York, and Thomson-Houston Electric Company of Lynn, Massachusetts, with the support of Drexel, Morgan & Co. Both plants continue to operate under the GE banner to this day. The company was incorporated in New York, with the Schenectady plant used as headquarters for many years thereafter. Around the same time, General Electric's Canadian counterpart, Canadian General Electric, was formed.

Question: This can give rise to the situation in which two dialects (defined according to this paradigm) with a somewhat distant genetic relationship are mutually more readily comprehensible than more closely related dialects. In one opinion, this pattern is clearly present among the modern Romance languages, with Italian and Spanish having a high degree of mutual comprehensibility, which neither language shares with French, despite some claiming that both languages are genetically closer to French than to each other:[citation needed] In fact, French-Italian and French-Spanish relative mutual incomprehensibility is due to French having undergone more rapid and more pervasive phonological change than have Spanish and Italian, not to real or imagined distance in genetic relationship. In fact, Italian and French share many more root words in common that do not even appear in Spanish.

Question: The first permanent settler was Jonathan Lambert, from Salem, Massachusetts, United States, who arrived at the islands in December 1810 with two other men. Lambert publicly declared the islands his property and named them the Islands of Refreshment. After being joined by an Andrew Millet, three of the four men died in 1812; however, the survivor among the original three permanent settlers, Thomas Currie (or Tommaso Corri) remained as a farmer on the island.
Try to answer this question if possible: Where did the only survivor, Thomas Currie, remain a dead man?
