Question: Answer the following question given this paragraph: Inertia is the tendency of an object to resist a change in its motion. All objects have inertia, whether they are stationary or moving. Inertia explains Newton's first law of motion, which states that an object at rest will remain at rest and an object in motion will stay in motion unless it is acted on by an unbalanced force. That's why Newton's first law of motion is sometimes called the law of inertia. You can see an animation of inertia at this URL:. Q: The tendency of an object to resist a change in its motion is called what? A:
OPTIONS:
- isolation
- kenetic force
- stabilization
- inertia
Answer: inertia

input with options: Answer the following question given this paragraph: Endocrine System: Iodine Deficiency, Hypothyroidism, and Hyperthyroidism As discussed above, dietary iodine is required for the synthesis of T3 and T4. But for much of the world's population, foods do not provide adequate levels of this mineral, because the amount varies according to the level in the soil in which the food was grown, as well as the irrigation and fertilizers used. Marine fish and shrimp tend to have high levels because they concentrate iodine from seawater, but many people in landlocked regions lack access to seafood. Thus, the primary source of dietary iodine in many countries is iodized salt. Fortification of salt with iodine began in the United States in 1924, and international efforts to iodize salt in the world's poorest nations continue today. Dietary iodine deficiency can result in the impaired ability to synthesize T3 and T4, leading to a variety of severe disorders. When T3 and T4 cannot be produced, TSH is secreted in increasing amounts. As a result of this hyperstimulation, thyroglobulin accumulates in the thyroid gland follicles, increasing their deposits of colloid. The accumulation of colloid increases the overall size of the thyroid gland, a condition called a goiter (Figure 17.14). A goiter is only a visible indication of the deficiency. Other iodine deficiency disorders include impaired growth and development, decreased fertility, and prenatal and infant death. Moreover, iodine deficiency is the primary cause of preventable mental retardation worldwide. Neonatal hypothyroidism (cretinism) is characterized by cognitive deficits, short stature, and sometimes deafness and muteness in children and adults born to mothers who were iodinedeficient during pregnancy. Q: A goiter is a visible indication of deficiency of what? A:
OPTIONS:
- arsenic
- chlorine
- water
- iodine
output: iodine

Q: Answer the following question given this paragraph: Many compounds form molecules, but ionic compounds form crystals instead. A crystal consists of many alternating positive and negative ions bonded together in a matrix. Look at the crystal of sodium chloride (NaCl) in the Figure below . The sodium and chloride ions are attracted to each other because they are oppositely charged, so they form ionic bonds. Q: What type of compounds can form crystals? A:

OPTIONS:
- integral compounds
- magnetic compounds
- molecular compounds
- ionic compounds

A: ionic compounds

input: OPTIONS:
- magnet
- alloy
- superconductor
- nonmetal Now, answer this question: Answer the following question given this paragraph: A nonmetal is an element that is generally a poor conductor of heat and electricity. Many properties of nonmetals are the opposite of those seen in metals. There is a wider variation in properties among the nonmetals than among the metals, as seen in Figure below . Nonmetals exist in all three states of matter at room temperature. The majority are gases, such as nitrogen and oxygen. Bromine is a liquid, and a few are solids, such as carbon and sulfur. In the solid state, nonmetals are brittle, meaning that they will shatter if struck with a hammer. The solids are not lustrous, and their melting points are generally much lower than those of metals. On the periodic table in the Figure above , the nonmetals are shaded green and appear to the right of the stair-step line. Q: An element that is generally a poor conductor of heat and electricity is known as a ______ A:
A:
output: nonmetal

Answer the following question given this paragraph: Fish have gills that allow them to "breathe" oxygen in water. Water enters the mouth, passes over the gills, and exits the body through a special opening. Gills absorb oxygen from the water as it passes over them. Q: What do fish have that allow them to "breathe" oxygen in water? A:

OPTIONS:
- lungs
- layers
- pores
- gills

Answer: gills

Q: Answer the following question given this paragraph: untreated, it produces severe brain damage and mental retardation. Albinism is caused by a defective enzyme that is unable to produce melanin, the pigment responsible for the color of skin and hair. Cystic fibrosis, the most common inherited disease in the United States, blocks pancreatic function and causes thick mucus secretions that make breathing difficult. An area of intense research in combating cancer involves the synthesis of drugs that stop uncontrolled cell growth by interfering with DNA replication. Q: What human disease is caused by a defective enzyme that is unable to produce melanin, the pigment responsible for the color of skin and hair? A:

OPTIONS:
- hemophilia
- anemia
- mutations
- albinism

A:
albinism
