Answer the following question given this paragraph: Common acids and the polyatomic anions derived from them have their own names and rules for nomenclature. The nomenclature of acids differentiates between oxoacids, in which the H+ ion is attached to an oxygen atom of a polyatomic ion, and acids in which the H + ion is attached to another element. Carboxylic acids are an important class of organic acids. Ammonia is an important base, as are its organic derivatives, the amines. Q: What class of acids do carboxylic acids fall under? Choices: - hydrochloric acids - inorganic acids - carbolic acids - organic acids A:
organic acids
Answer the following question given this paragraph: A model is a representation of an object, system, or process. For example, a road map is a representation of an actual system of roads on the ground. Models are very useful in science. They provide a way to investigate things that are too small, large, complex, or distant to investigate directly. To be useful, a model must closely represent the real thing in important ways, but it must be simpler and easier to understand than the real thing. Q: What term means a representation of an object, system, or process? Choices: - pattern - presentation - icon - model A:
model
Q: Answer the following question given this paragraph: The combined gas law, , is true for a particular sample of gas. If any gas is added or allowed to leak out, however, the relationship is lost. In order to get a relationship that is true for any sample of gas, it is necessary to incorporate a term for the amount of gas. From observations as simple as blowing up a balloon, it is clear that increasing the amount of gas increases the volume. Q: From observations as simple as blowing up a balloon, it is clear that increasing the amount of gas increases what else? Choices: - area - every volume - the shift - the volume A:
A: the volume
Question: Answer the following question given this paragraph: Q: What are named for major physical or climatic features and for their predominant vegetation? Choices: - terrestrial substrates - geological formations - celestial bodies - terrestrial biomes A:
Answer: terrestrial biomes

Answer the following question given this paragraph: The parts of the ears involved in balance are the semicircular canals. These are the curved structures above the cochlea in the inner ear in Figure above . Like the cochlea, the semicircular canals contain liquid and are lined with tiny hair cells. As the head changes position, the liquid moves. This causes the hair cells to bend. The bending of the hair cells triggers nerve impulses that travel to the cerebellum in the brain. The cerebellum uses the information to maintain balance. Q: Involved in balance, the semicircular canals are parts of what organs? Choices: - eyes - lungs - ovaries - ears A:
**Answer**
ears

Answer the following question given this paragraph: Do you like toast? Did you ever look inside a toaster while it's toasting bread? When you push down the lever to turn on the toaster, the metal heating element inside starts to glow orange or red almost instantly. You can see the glowing heating element inside this yellow toaster. The glowing metal shows that the heating element has become very hot. It gets hot so quickly because metals are good conductors of thermal energy. Q: Why does the heating element of a toaster get hot so quickly? Choices: - charged battery - magnetic force - good insulator - good conductor A:
(A).
good conductor
