Q: Answer the following question given this paragraph: Snow falls when water vapor condenses as ice crystals. The air temperature is below freezing all the way to the ground, so the ice crystals remain frozen. They fall as flakes. Sleet forms when snow melts as it falls through a layer of warm air and then refreezes. It turns into small, clear ice pellets as it passes through a cold layer near the ground. Freezing rain falls as liquid water. It freezes on contact with cold surfaces near the ground. It may cover everything with a glaze of ice. If the ice is thick, its weight may break tree branches and pull down power lines. Hail is another type of frozen precipitation. Hail forms in thunderstorms when strong updrafts carry rain high into the troposphere. The rain freezes into balls of ice called hailstones. This may happen over and over again until the hailstones are as big as baseballs. Hail forms only in cumulonimbus clouds. Q: What are two types of frozen percipitation? Choices: - icycles and icebergs - rain and hail - ice and frost - snow and hail A:
A: snow and hail
Question: Answer the following question given this paragraph: The halogen group is quite diverse. It includes elements that occur in three different states of matter at room temperature. Fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. Halogens also vary in color, as you can see in the Figure below . Fluorine and chlorine are green, bromine is red, and iodine and astatine are nearly black. Like other nonmetals, halogens cannot conduct electricity or heat. Compared with most other elements, halogens have relatively low melting and boiling points. You can watch a lab demonstration of the melting and boiling points of halogens at this URL: http://www. youtube. com/watch?v=yP0U5rGWqdg . Q: What makes the halogen group so diverse? Choices: - contains alloys - a single state of matter - bonds easily - three different states of matter A:
Answer: three different states of matter

Answer the following question given this paragraph: Consumers are organisms that depend on other organisms for food. They take in organic molecules by essentially "eating" other living things. They include all animals and fungi. (Fungi don't really "eat"; they absorb nutrients from other organisms. ) They also include many bacteria and even a few plants, such as the pitcher plant in Figure below . Consumers are also called heterotrophs. Heterotrophs are classified by what they eat:. Q: Consumers are organisms that depend on other organisms for what? Choices: - knowledge - reproduction - shelter - food A:
food
