Answer the following question given this paragraph: A resource is renewable if it is remade by natural processes at the same rate that humans use it up. Sunlight and wind are renewable resources because they will not be used up ( Figure below ). The rising and falling of ocean tides is another example of a resource in unlimited supply. A sustainable resource is a resource that is used in a way that meets the needs of the present without keeping future generations from meeting their needs. People can sustainably harvest wood, cork, and bamboo. Farmers can also grow crops sustainably by not planting the same crop in their soil year after year. Planting the same crop each year can remove nutrients from the soil. This means that wood, cork, bamboo, and crops can be sustainable resources. Q: What is the term for a resource that is used in a way that meets the needs of the present without keeping future generations from meeting their needs? Choices: - tolerable - innovative - structural - sustainable A:
sustainable
Q: Answer the following question given this paragraph: In a wheel and axle, force may be applied either to the wheel or to the axle. In both cases, the direction of the force does not change, but the force is either increased or applied over a greater distance. Q: In a wheel and axle, when force is applied either to the wheel or axle, what aspect of the force does not change? Choices: - speed - pressure - shift - direction A:
A: direction
Question: Answer the following question given this paragraph: Nonmetals tend to gain electrons in chemical reactions and have a high attraction to electrons within a compound. The most reactive nonmetals reside in the upper right portion of the periodic table. Since the noble gases are an unusually unreactive group, the element fluorine is the most reactive nonmetal. It is also not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances. Q: What group of gases are unusually unreactive? Choices: - volcanic gases - greenhouse gases - halogens - noble gases A:
Answer: noble gases

Answer the following question given this paragraph: Almost all fungi reproduce asexually by producing spores. A fungi spore is a haploid cell produced by mitosis from a haploid parent cell. It is genetically identical to the parent cell. Fungi spores can develop into new haploid individuals without being fertilized. Q: Most fungi reproduce asexually by producing what? Choices: - seeds - ions - toxins - spores A:
**Answer**
spores

Answer the following question given this paragraph: Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases. All four types of friction are described below. You can see a video demonstration of the different types at this URL:. Q: What 3 types of friction occur between solid surfaces? Choices: - static , arching , rolling - static,desending,sliding - static , ascending , rolling - static, sliding, rolling A:
**Answer**
static, sliding, rolling
