Q: Answer the following question given this paragraph: Giant steps in science may occur if a scientist introduces a major new idea. For example, in 1666, Isaac Newton introduced the idea that gravity is universal. People had long known that things fall to the ground because they are attracted by Earth. But Newton proposed that everything in the universe exerts a force of attraction on everything else. This idea is known as Newton's law of universal gravitation. Q: Who proposed that everything in the universe exerts a force of attraction on everything else? A:
Answer: newton

Answer the following question given this paragraph: An ecosystem is a unit of nature. It consists of all the biotic and abiotic factors in an area and all the ways in which they interact. Q: What includes all the biotic and abiotic factors in an area and how they interact? A:
OPTIONS:
- biome
- habitat

ecosystem

Answer the following question given this paragraph: Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant. Figure below shows the life cycle of moss. The familiar, green, photosynthetic moss plants are gametophytes . The sporophyte generation is very small and dependent on the gametophyte plant. Q: What are the only plants with a life cycle in which the gametophyte generation is dominant? A:
OPTIONS:
- vascular plants
- nonpermeable
- photoreactive
- nonvascular

Answer: nonvascular

Question: Answer the following question given this paragraph: TiCl4(l) + 2Mg(s) Ti(s) + 2MgCl2(s) The only other alkaline earth that is widely used as the metal is beryllium, which is extremely toxic. Ingestion of beryllium or exposure to beryllium-containing dust causes a syndrome called berylliosis, characterized by severe inflammation of the respiratory tract or other tissues. A small percentage of beryllium dramatically increases the strength of copper or nickel alloys, which are used in nonmagnetic, nonsparking tools (such as wrenches and screwdrivers), camera springs, and electrical contacts. The low atomic number of beryllium gives it a very low tendency to absorb x-rays and makes it uniquely suited for applications involving radioactivity. Both elemental Be and BeO, which is a high-temperature ceramic, are used in nuclear reactors, and the windows on all x-ray tubes and sources are made of beryllium foil. Millions of tons of calcium compounds are used every year. As discussed in earlier chapters, CaCl 2 is used as "road salt" to lower the freezing point of water on roads in cold temperatures. In addition, CaCO 3 is a. Q: What aspect of beryllium allows it to absorb x-rays? A:
OPTIONS:
- magnetism
- relative atomic number
- high atomic number
- low atomic number
Answer: low atomic number
