input with options: Answer the following question given this paragraph: The frequency of sound waves is measured in hertz (Hz), or the number of waves that pass a fixed point in a second. Human beings can normally hear sounds with a frequency between about 20 Hz and 20,000 Hz. Sounds with frequencies below 20 hertz are called infrasound . Infrasound is too low-pitched for humans to hear. Sounds with frequencies above 20,000 hertz are called ultrasound . Ultrasound is too high-pitched for humans to hear. Q: The frequency of sound waves is measured in what unit? A:
OPTIONS:
- watt
- rads
- decibel
- hertz
output: hertz

Q: Answer the following question given this paragraph: Symbiosis is a close relationship between two species in which at least one species benefits. Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed. Q: What type of interspecies relationship involves one party being actively harmed? A:

OPTIONS:
- mosaicism
- symbiosis
- mutualism
- parasitism

A: parasitism

input: OPTIONS:
- claustrophobic
- anti-hydral
- hydrogenic
- hydrophobic Now, answer this question: Answer the following question given this paragraph: London interactions c. London dispersion forces Hydrophilic and Hydrophobic Solutes A solute can be classified as hydrophilic (literally, "water loving"), meaning that it has an electrostatic attraction to water, or hydrophobic ("water fearing"), meaning that it repels water. A hydrophilic substance is polar and often contains OH or NH groups that can form hydrogen bonds to water. For example, glucose with its five OH groups is hydrophilic. In contrast, a hydrophobic substance may be polar but usually contains CH bonds that do not interact favorably with water, as is the case with naphthalene and n-octane. Hydrophilic substances tend to be very soluble in water and other strongly polar solvents, whereas hydrophobic substances are essentially insoluble in water and soluble in nonpolar solvents such as benzene and cyclohexane. The difference between hydrophilic and hydrophobic substances has substantial consequences in biological systems. For example, vitamins can be classified as eitherfat soluble or water soluble. Fatsoluble vitamins, such as vitamin A, are mostly nonpolar, hydrophobic molecules. As a result, they tend to be absorbed into fatty tissues and stored there. In contrast, water-soluble vitamins, such as vitamin C, are polar, hydrophilic molecules that circulate in the blood and intracellular fluids, which are primarily aqueous. Water-soluble vitamins are therefore excreted much more rapidly from the body and must be replenished in our daily diet. A comparison of the chemical structures of vitamin A and vitamin C quickly reveals why one is hydrophobic and the other hydrophilic. Q: What term is used to describe a solute that is water fearing? A:
A:
output: hydrophobic

Answer the following question given this paragraph: The process in which organ systems work to maintain a stable internal environment is called homeostasis . Keeping a stable internal environment requires constant adjustments. Here are just three of the many ways that human organ systems help the body maintain homeostasis:. Q: The process in which organ systems work to maintain a stable internal environment is called what? A:

OPTIONS:
- consciousness
- thrombosis
- ketosis
- homeostasis

Answer: homeostasis

Problem: OPTIONS:
- tools
- anesthesia
- braces
- fillings
Q: Answer the following question given this paragraph: Dentists occasionally use metallic mixtures called amalgams for fillings. If an amalgam contains zinc, however, water can contaminate the amalgam as it is being manipulated, producing hydrogen gas under basic conditions. As the filling hardens, the gas can be released, causing pain and cracking the tooth. Write a balanced chemical equation for this reaction. Q: Dentists occasionally use metallic mixtures called amalgams for what? A:
Answer: fillings
