Q: Answer the following question given this paragraph: Plates move for two reasons. Upwelling mantle at the mid-ocean ridge pushes plates outward. Cold lithosphere sinking into the mantle at a subduction zone pulls the rest of the plate down with it. Q: Upwelling mantle at the mid-ocean ridge pushes plates in which direction? A:
Answer: outward

Problem:OPTIONS:
- protons
- electrons
- molecules
- neutrons

Answer the following question given this paragraph: Heavier isotopes of plutoniumPu-240, Pu-241, and Pu-242are also produced when lighter plutonium nuclei capture neutrons. Some of this highly radioactive plutonium is used to produce military weapons, and the rest presents a serious storage problem because they have half-lives from thousands to hundreds of thousands of years. Although they have not been prepared in the same quantity as plutonium, many other synthetic nuclei have been produced. Nuclear medicine has developed from the ability to convert atoms of one type into other types of atoms. Radioactive isotopes of several dozen elements are currently used for medical applications. The radiation produced by their decay is used to image or treat various organs or portions of the body, among other uses. The elements beyond element 92 (uranium) are called transuranium elements. As of this writing, 22 transuranium elements have been produced and officially recognized by IUPAC; several other elements have formation claims that are waiting for approval. Some of these elements are shown in Table 21.3. Preparation of Some of the Transuranium Elements Name. Q: Heavier isotopes of plutonium are also produced when lighter plutonium nuclei capture what? A:
****
A: neutrons

Answer the following question given this paragraph: Heat from a wood fire can boil a pot of water. If you put an egg in the pot, you can eat a hard boiled egg in 15 minutes (cool it down first!). The energy to cook the egg was stored in the wood. The wood got that energy from the Sun when it was part of a tree. The Sun generated the energy by nuclear fusion. You started the fire with a match. The head of the match stores energy as chemical energy. That energy lights the wood on fire. The fire burns as long as there is energy in the wood. Once the wood has burned up, there is no energy left in it. The fire goes out. Q: How does the sun generate energy? A:
OPTIONS:
- atomic division
- matter multiplication
- certain fusion
- nuclear fusion
nuclear fusion

Answer the following question given this paragraph: 23.6 Accessory Organs in Digestion: The Liver, Pancreas, and Gallbladder Chemical digestion in the small intestine cannot occur without the help of the liver and pancreas. The liver produces bile and delivers it to the common hepatic duct. Bile contains bile salts and phospholipids, which emulsify large lipid globules into tiny lipid droplets, a necessary step in lipid digestion and absorption. The gallbladder stores and concentrates bile, releasing it when it is needed by the small intestine. The pancreas produces the enzyme- and bicarbonate-rich pancreatic juice and delivers it to the small intestine through ducts. Pancreatic juice buffers the acidic gastric juice in chyme, inactivates pepsin from the stomach, and enables the optimal functioning of digestive enzymes in the small intestine. Q: Chemical digestion in the small intestine cannot occur without the help of the pancreas and what bile-producing organ? A:
OPTIONS:
- kidney
- heart
- stomach
- liver

Answer: liver

Question: Answer the following question given this paragraph: Q: What is the study of the chemical elements necessary for plant growth called? A:
OPTIONS:
- photosynthesis
- phototropism
- plant propagation
- plant nutrition
Answer: plant nutrition

input: OPTIONS:
- gravity
- filter
- weight
- wavelength Now, answer this question: Answer the following question given this paragraph: Lasers Most light emitted by atoms is polychromaticcontaining more than one wavelength. In contrast, lasers (from light amplification by stimulated emission of radiation) emitmonochromatic light a single wavelength only. Lasers have many applications in fiber-optic telecommunications, the reading and recording of compact discs (CDs) and digital video discs (DVDs), steel cutting, and supermarket checkout scanners. Laser beams are generated by the same general phenomenon that gives rise to emission spectra, with one difference: only a single excited state is produced, which in principle results in only a single frequency of emitted light. In practice, however, inexpensive commercial lasers actually emit light with a very narrow range of wavelengths. How a CD player uses a laser to read a CD. Inside a CD is a flat, light-reflecting layer called "land. " On the land are many "pits" recorded in a spiral-shaped track. (From the laser's point of view, pits are actually the "bumps" shown here because the master disc with pits is duplicated negatively, turning the pits into bumps. ) Pits have the same light-reflecting surface as land, but there are differences in the frequencies of the reflected light in the pit and the land, making light reflected by pits relatively dark compared with light reflected by land. Q: Light emitted by atoms is polychromaticcontaining more than one of these? A:
A:
output:
wavelength
