input: OPTIONS:
- organics
- gases
- oils
- metals Now, answer this question: Answer the following question given this paragraph: While many elements differ dramatically in their chemical and physical properties, some elements have similar properties. We can identify sets of elements that exhibit common behaviors. For example, many elements conduct heat and electricity well, whereas others are poor conductors. These properties can be used to sort the elements into three classes: metals (elements that conduct well), nonmetals (elements that conduct poorly), and metalloids (elements that have properties of both metals and nonmetals). The periodic table is a table of elements that places elements with similar properties close together (Figure 1.22). You will learn more about the periodic table as you continue your study of chemistry. Q: What elements tend to conduct well? A:
A:
output: metals

Answer the following question given this paragraph: Chemical Digestion in the Small Intestine The digestion of proteins and carbohydrates, which partially occurs in the stomach, is completed in the small intestine with the aid of intestinal and pancreatic juices. Lipids arrive in the intestine largely undigested, so much of the focus here is on lipid digestion, which is facilitated by bile and the enzyme pancreatic lipase. Moreover, intestinal juice combines with pancreatic juice to provide a liquid medium that facilitates absorption. The intestine is also where most water is absorbed, via osmosis. The small intestine's absorptive cells also synthesize digestive enzymes and then place them in the plasma membranes of the microvilli. This distinguishes the small intestine from the stomach; that is, enzymatic digestion occurs not only in the lumen, but also on the luminal surfaces of the mucosal cells. For optimal chemical digestion, chyme must be delivered from the stomach slowly and in small amounts. This is because chyme from the stomach is typically hypertonic, and if large quantities were forced all at once into the small intestine, the resulting osmotic water loss from the blood into the intestinal lumen would result in potentially life-threatening low blood volume. In addition, continued digestion requires an upward adjustment of the low pH of stomach chyme, along with rigorous mixing of the chyme with bile and pancreatic juices. Both processes take time, so the pumping action of the pylorus must be carefully controlled to prevent the duodenum from being overwhelmed with chyme. Q: What two types of juices help digestion within the small intestine? A:

OPTIONS:
- chyme and phloem
- amniotic fluid, bile
- bile and lymph
- intestinal and pancreatic

Answer: intestinal and pancreatic

Problem: OPTIONS:
- eight
- zero
- two
- four
Q: Answer the following question given this paragraph: Dietary proteins are broken down during digestion to provide the amino acids needed for protein synthesis. Any extra proteins in the diet not needed for this purpose are used for energy or stored as fat. One gram of proteins provides 4 Calories of energy. Q: One gram of proteins provides how many calories of energy? A:
Answer: four

Problem:OPTIONS:
- solvent
- underfoot
- solid
- permafrost

Answer the following question given this paragraph: Polar climates are found near the North and South Poles. They also occur on high mountains at lower latitudes. The summers are very cool, and the winters are frigid. Precipitation is very low because it's so cold. The growing season is very short. Tundra prefers areas of permafrost. Permafrost is a lower layer of soil that is permanently frozen. Tundra also refers to a treeless plain with small plants. You can see examples of polar climates pictured below. Q: What do you call the lower layer of soil that is permanently frozen, and is a frequent feature of tundra? A:
****
A: permafrost

Answer the following question given this paragraph: Gas molecules are exceedingly rare in the exosphere. Q: Molecules of gas are rare in what outermost region of the planet's atmosphere? A:
OPTIONS:
- ozone layer
- thermosphere
- ionosphere
- exosphere
exosphere

Answer the following question given this paragraph: Higher pressures increase the solubility of gases. You are probably familiar with this concept as it relates to carbonated beverages. Before opening the container, the inside is pressurized, so a large amount of CO 2 is dissolved in the liquid. After opening, the pressure decreases (to the ambient pressure), so the solubility of CO 2 drops, causing it to bubble out of solution. Because they are not compressible like gases, solid and liquid solutes do not have noticeable changes in solubility at different external pressures. Q: Higher pressures increase the solubility of what? A:
OPTIONS:
- molecules
- fuels
- bases
- gases

Answer:
gases
