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? Choices: - kidney - heart - stomach - liver A:
liver
Answer the following question given this paragraph: Q: What is the study of the chemical elements necessary for plant growth called? Choices: - photosynthesis - phototropism - plant propagation - plant nutrition A:
plant nutrition
Q: Answer the following question given this paragraph: Q: Sister chromatids separate as part of anaphase in what process? Choices: - osmosis - vesicles - angiogenesis - mitosis A:
A: mitosis
Question: Answer the following question given this paragraph: Once we reach neon, a noble gas, all of the 2p orbitals will be completely full. Neon has a configuration of 1s 2 2s 2 2p 6 . Any further electrons will need to go in the next highest energy orbital, which would be the 3s orbital. Q: Neon is an example of what kind of gas? Choices: - ideal - inert - natural - noble A:
Answer: noble

Answer the following question given this paragraph: With over twenty million known organic compounds in existence, it would be very challenging to memorize chemical reactions for each one. Fortunately, molecules with similar functional groups tend to undergo similar reactions. A functional group is defined as an atom or group of atoms within a molecule that has similar chemical properties whenever it appears in various compounds. Even if other parts of the molecule are quite different, certain functional groups tend to react in certain ways. Q: What is the germ for a group of atoms within a molecule that reacts similarly anywhere it appears in different compounds? Choices: - atomic group - thermal group - molecular group - functional group A:
**Answer**
functional group
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? Choices: - gravity - filter - weight - wavelength A:
wavelength
