Answer the following question given this paragraph: The ears are also responsible for the sense of balance. Balance is the ability to sense and maintain body position. The semicircular canals inside the ear (see Figure above ) contain fluid that moves when the head changes position. Tiny hairs lining the semicircular canals sense movement of the fluid. In response, they send nerve impulses to the vestibular nerve, which carries the impulses to the brain. The brain interprets the impulses and sends messages to the peripheral nervous system. This system maintains the body's balance by triggering contractions of skeletal muscles as needed. Q: What external feature in human beings is responsible for balance? A:
OPTIONS:
- tails
- brain
- hands
- ears
ears

Answer the following question given this paragraph: Antacids are bases that neutralize acids in the digestive tract. Magnesium hydroxide [Mg(OH)2] is one such antacid. It reacts with hydrochloric acid in the stomach according to the following reaction: Mg(OH)2 + 2HCl MgCl2 + 2H2O How many grams of HCl can a 200 mg dose of Mg(OH)2 neutralize?. Q: Antacids are bases that neutralize what in the digestive tract? A:
OPTIONS:
- fats
- hormones
- salts
- acids

Answer: acids

Q: Answer the following question given this paragraph: Because of the wave character of matter, the idea of well-defined orbits gives way to a model in which there is a cloud of probability, consistent with Heisenberg's uncertainty principle. Figure 30.48 shows how this applies to the ground state of hydrogen. If you try to follow the electron in some well-defined orbit using a probe that has a small enough wavelength to get some details, you will instead knock the electron out of its orbit. Each measurement of the electron's position will find it to be in a definite location somewhere near the nucleus. Repeated measurements reveal a cloud of probability like that in the figure, with each speck the location determined by a single measurement. There is not a well-defined, circular-orbit type of distribution. Nature again proves to be different on a small scale than on a macroscopic scale. Q: Because of the wave character of matter, the idea of well-defined orbits gives way to a model in which there is a cloud of what? A:

OPTIONS:
- particles
- mutation
- chaos
- probability

A: probability

Answer the following question given this paragraph: Earthworms are deposit feeders. They burrow through the ground, eating soil and extracting organic matter from it. Earthworm feces, called worm casts, are very rich in plant nutrients. Earthworm burrows help aerate soil, which is also good for plants. Q: What type of feeders are earthworms? A:
OPTIONS:
- middle
- top
- oil
- deposit
deposit
