Answer the following question given this paragraph: The type of construction has a tremendous effect on what happens during an earthquake. Damage and deaths are directly affected by the construction in an earthquake. For example, enormous damage was done in the 2011 Christchurch, New Zealand earthquake. However, far less was damaged in an earthquake of the same magnitude near the area in Iceland seen above. Q: Damages and deaths are directly affected by what in an earthquake? Choices: - structures - shaking - natural - construction A:
construction
Answer the following question given this paragraph: Equilibrium (Balance) Along with audition, the inner ear is responsible for encoding information about equilibrium, the sense of balance. A similar mechanoreceptora hair cell with stereociliasenses head position, head movement, and whether our bodies are in motion. These cells are located within the vestibule of the inner ear. Head position is sensed by the utricle and saccule, whereas head movement is sensed by the semicircular canals. The neural signals generated in the vestibular ganglion are transmitted through the vestibulocochlear nerve to the brain stem and cerebellum. The utricle and saccule are both largely composed of macula tissue (plural = maculae). The macula is composed of hair cells surrounded by support cells. The stereocilia of the hair cells extend into a viscous gel called the otolithic membrane (Figure 14.11). On top of the otolithic membrane is a layer of calcium carbonate crystals, called otoliths. The otoliths essentially make the otolithic membrane top-heavy. The otolithic membrane moves separately from the macula in response to head movements. Tilting the head causes the otolithic membrane to slide over the macula in the direction of gravity. The moving otolithic membrane, in turn, bends the sterocilia, causing some hair cells to depolarize as others hyperpolarize. The exact position of the head is interpreted by the brain based on the pattern of hair-cell depolarization. Q: On top of the otolithic membrane is a layer of calcium carbonate crystals, called what? Choices: - cones - gonads - calcites - otoliths A:
otoliths
Q: Answer the following question given this paragraph: 19.4 Community Ecology Communities include all the different species living in a given area. The variety of these species is referred to as biodiversity. Many organisms have developed defenses against predation and herbivory, including mechanical defenses, warning coloration, and mimicry. Two species cannot exist indefinitely in the same habitat competing directly for the same resources. Species may form symbiotic relationships such as commensalism, mutualism, or parasitism. Community. Q: Commensalism, mutualism, and parasitism are known as what type of relationships? Choices: - simple - peculiar - various - symbiotic A:
A: symbiotic
Question: Answer the following question given this paragraph: Ammonia is a colorless gas with a sharp, pungent odor. Smelling salts utilize this powerful odor. Gaseous ammonia readily liquefies to give a colorless liquid that boils at 33 C. Due to intermolecular hydrogen bonding, the enthalpy of vaporization of liquid ammonia is higher than that of any other liquid except water, so ammonia is useful as a refrigerant. Ammonia is quite soluble in water (658 L at STP dissolves in 1 L H2O). The chemical properties of ammonia are as follows: 1. Ammonia acts as a Brnsted base, as discussed in the chapter on acid-base chemistry. The ammonium ion is. Q: What is the colorless gas with a sharp, pungent odor used in smelling salts? Choices: - nitrogen - hydrogen - helium - ammonia A:
Answer: ammonia

Answer the following question given this paragraph: Scientists think the solar system formed from a big cloud of gas and dust, called a nebula . This is the solar nebula hypothesis. The nebula was made mostly of hydrogen and helium. There were heavier elements too. Gravity caused the nebula to contract ( Figure below ). Q: Scientists think the solar system formed from a big cloud of gas and dust called what? Choices: - comet - supernova - Oort cloud - nebula A:
**Answer**
nebula
Answer the following question given this paragraph: Electric current is a continuous flow of electric charge. It is measured in amperes (A). Direct current (DC) flows in just one direction. Alternating current (AC) keeps reversing direction. Q: What is a continuous flow of electric charge called? Choices: - powered current - microwave current - magnetism - electric current A:
electric current
