Student A:The fight-or-flight response (also called hyperarousal, or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It was first described by Walter Bradford Cannon. His theory states that animals react to threats with a general discharge of the sympathetic nervous system, preparing the animal for fighting or fleeing. More specifically, the adrenal medulla produces a hormonal cascade that results in the secretion of catecholamines, especially norepinephrine and epinephrine. The hormones estrogen, testosterone, and cortisol, as well as the neurotransmitters dopamine and serotonin, also affect how organisms react to stress.

Answer this question based on the passage: in response to an acute stressor epinephrine is released from which structure?
Student B:OK... This is the relevant information: More specifically, the adrenal medulla produces a hormonal cascade that results in the secretion of catecholamines, especially norepinephrine and epinephrine.
the adrenal medulla.

Problem:Mark Gilbert McKinney, known professionally as Gil McKinney, (born February 5, 1979) is an American film and television actor. He is best known for playing Dr. Paul Grady on ER, Derek Bishop on Friday Night Lights, and Prince Eric in Once Upon a Time, and for being the voice and face (via MotionScan) of Jack Kelso in the video game L.A. Noire. Gil also appeared in Supernatural as Henry Winchester.

Based on this passage, who plays eric on once upon a time?
Solution:OK... To answer the question, consider the following: He is best known for playing Dr. Paul Grady on ER, Derek Bishop on Friday Night Lights, and Prince Eric in Once Upon a Time, and for being the voice and face (via MotionScan) of Jack Kelso in the video game L.A. Noire.

Student A:Taste buds contain the taste receptor cells, which are also known as gustatory cells. The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek and epiglottis. These structures are involved in detecting the five elements of taste perception: salty, sour, bitter, sweet and umami; through the combination of these elements we detect "flavors." A popular myth assigns these different tastes to different regions of the tongue; in reality these tastes can be detected by any area of the tongue. Via small openings in the tongue epithelium, called taste pores, parts of the food dissolved in saliva come into contact with the taste receptors. These are located on top of the taste receptor cells that constitute the taste buds. The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves.

Answer this question based on the passage: where are taste buds located in your mouth?
Student B:OK... To answer the above question, the relevant sentence is: The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek and epiglottis.
around the small structures known as papillae found on the upper surface of the tongue , soft palate , upper esophagus , the cheek and epiglottis.

Problem:Passage: An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H ions) across a membrane. This creates an electrochemical proton gradient that drives the synthesis of adenosine triphosphate (ATP), a molecule that stores energy chemically in the form of highly strained bonds. The molecules of the chain include peptides, enzymes (which are proteins or protein complexes), and others. The final acceptor of electrons in the electron transport chain during aerobic respiration is molecular oxygen although a variety of acceptors other than oxygen such as sulfate exist in anaerobic respiration.

Question: Based on this passage, what is the final electron acceptor of the electron transport system?
Solution:OK... To answer the above question, the relevant sentence is: The final acceptor of electrons in the electron transport chain during aerobic respiration is molecular oxygen although a variety of acceptors other than oxygen such as sulfate exist in anaerobic respiration.
molecular oxygen.

Student A:Thomas Jefferson had "potatoes served in the French manner" at a White House dinner in 1802. The expression "French fried potatoes" first occurred in print in English in the 1856 work Cookery for Maids of All Work by E. Warren: "French Fried Potatoes. -- Cut new potatoes in thin slices, put them in boiling fat, and a little salt; fry both sides of a light golden brown colour; drain." This account referred to thin, shallow-fried slices of potato -- it is not clear where or when the now familiar deep-fried batons or fingers of potato were first prepared. In the early 20th century, the term "French fried" was being used in the sense of "deep-fried" for foods like onion rings or chicken.

Where did they get the name french fries?
Student B:OK... To answer the question, consider the following: The expression "French fried potatoes" first occurred in print in English in the 1856 work Cookery for Maids of All Work by E. Warren: "French Fried Potatoes.
first occurred in print in English in the 1856 work Cookery for Maids of All Work by E. Warren.

Student A:Passage: The Louisiana Purchase (French: Vente de la Louisiane "Sale of Louisiana") was the acquisition of the Louisiana territory (828,000 square miles or 2.14 million km2) by the United States from France in 1803. The U.S. paid fifty million francs ($11,250,000 / 9,100,000) and a cancellation of debts worth eighteen million francs ($3,750,000) for a total of sixty-eight million francs ($15 million, equivalent to $300 million in 2016). The Louisiana territory included land from fifteen present U.S. states and two Canadian provinces. The territory contained land that forms Arkansas, Missouri, Iowa, Oklahoma, Kansas, and Nebraska; the portion of Minnesota west of the Mississippi River; a large portion of North Dakota; a large portion of South Dakota; the northeastern section of New Mexico; the northern portion of Texas; the area of Montana, Wyoming, and Colorado east of the Continental Divide; Louisiana west of the Mississippi River (plus New Orleans); and small portions of land within the present Canadian provinces of Alberta and Saskatchewan. Its non-native population was around 60,000 inhabitants, of whom half were African slaves.

Question: Based on this passage, who did the us buy the louisiana territory from?
Student B:
OK... The important part for answering this question is: The Louisiana Purchase (French: Vente de la Louisiane "Sale of Louisiana") was the acquisition of the Louisiana territory (828,000 square miles or 2.14 million km2) by the United States from France in 1803.
