Problem:OPTIONS:
- purple phosphorus
- yellow phosphorous
- green phosphorus
- white phosphorus

Answer the following question given this paragraph: Phosphorus exists as several allotropes, the most common being red, black, and white phosphorus. White phosphorus consists of tetrahedral P4 molecules and melts at 44.15C; it is converted to red phosphorus by heating at 400C for several hours. The chemical differences between red and white phosphorus are considerable: white phosphorus burns in air, whereas red phosphorus is stable; white phosphorus is soluble in organic compounds, whereas red phosphorus is not; white phosphorus melts at 44.15C, whereas red phosphorus melts at 597C. If the enthalpy of fusion of white phosphorus is 0.659 kJ/mol, what is its S? Black phosphorus is even less reactive than red. Based on this information, which allotrope would you predict to have the highest entropy? the lowest? Why?. Q: Phosphorus exists as several allotropes, the most common being red, black, and what? A:
****
A: white phosphorus

Answer the following question given this paragraph: Runoff is likely to cause more erosion if the land is bare. Plants help hold the soil in place. The runoff water in Figure below is brown because it eroded soil from a bare, sloping field. Can you find evidence of erosion by runoff where you live? What should you look for?. Q: Runoff is likely to cause more what if the land is bare? A:
OPTIONS:
- abrasion
- sediment
- weathering
- erosion
erosion

Answer the following question given this paragraph: Many plants also produce hormones and toxins to fight pathogens. For example, willow trees, like the one in Figure below , produce salicylic acid to kill bacteria. The same compound is used in many acne products for the same reason. Q: What do willow trees produce to kill bacteria? A:
OPTIONS:
- facultative acid
- Posion
- bacterial acid
- salicylic acid

Answer: salicylic acid

Question: Answer the following question given this paragraph: Pancreatic Juice The pancreas produces over a liter of pancreatic juice each day. Unlike bile, it is clear and composed mostly of water along with some salts, sodium bicarbonate, and several digestive enzymes. Sodium bicarbonate is responsible for the slight alkalinity of pancreatic juice (pH 7.1 to 8.2), which serves to buffer the acidic gastric juice in chyme, inactivate pepsin from the stomach, and create an optimal environment for the activity of pH-sensitive digestive enzymes in the small intestine. Pancreatic enzymes are active in the digestion of sugars, proteins, and fats. The pancreas produces protein-digesting enzymes in their inactive forms. These enzymes are activated in the duodenum. If produced in an active form, they would digest the pancreas (which is exactly what occurs in the disease, pancreatitis). The intestinal brush border enzyme enteropeptidase stimulates the activation of trypsin from trypsinogen of the pancreas, which in turn changes the pancreatic enzymes procarboxypeptidase and chymotrypsinogen into their active forms, carboxypeptidase and chymotrypsin. The enzymes that digest starch (amylase), fat (lipase), and nucleic acids (nuclease) are secreted in their active forms, since they do not attack the pancreas as do the protein-digesting enzymes. Q: Unlike liver bile, 'juice' produced by what organ is clear and composed mostly of water along with some salts, sodium bicarbonate, and digestive enzymes? A:
OPTIONS:
- spleen
- gallbladder
- stomach
- pancreas
Answer: pancreas

input with options: Answer the following question given this paragraph: Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below , look similar on the outside. They also have the same function. However, wings evolved independently in the two groups of animals. This is apparent when you compare the pattern of bones inside the wings. Q: What term is used to describe structures that are similar in unrelated organisms? A:
OPTIONS:
- reproductive
- symbolic
- isolated
- analogous
output: analogous

Problem: OPTIONS:
- no energy
- high energy
- low sand density
- low energy
Q: Answer the following question given this paragraph: Waves also move sand from the beaches on shore to bars of sand offshore as the seasons change. In the summer, waves have lower energy so they bring sand up onto the beach. In the winter, higher energy waves bring the sand back offshore. Q: What causes waves to bring sand up onto the beach during summers? A:
Answer:
low energy
