Answer the following question given this paragraph: Meanders form because water erodes the outside of curves and deposits eroded material on the inside. Over time, the curves shift position. Q: What form because water erodes the outside of curves and deposits eroded material on the inside? Choices: - inlets - cascades - caverns - meanders A:
meanders
Answer the following question given this paragraph: One important characteristic that determines the way in which elements behave is the total size of each atom. Free atoms are spherical in shape, so the relative sizes of the elements can be compared by looking at each atom's atomic radius , which is the distance from an atom's nucleus to the electrons in the outermost orbitals. You might expect atoms to generally grow larger as they go up in atomic number (which is equal to the total number of electrons in the neutral atom). Indeed, if you look at a single group of the periodic table, this trend holds true. Iodine is larger than bromine, which is in turn larger than chlorine and fluorine. In the case of a single group, each successive row places electrons in a higher principal energy level. Since higher energy levels are farther from the nucleus on average, this results in a larger total volume occupied by the atom. Q: Free atoms are spherical in shape, so the relative sizes of the elements can be compared by looking at each atom's atomic what? Choices: - weight - axis - angles - radius A:
radius
Q: Answer the following question given this paragraph: Minerals are made by natural processes. The processes that make minerals happen in or on the Earth. For example, when hot lava cools, mineral crystals form. Minerals also precipitate from water. Some minerals grow when rocks are exposed to high pressures and temperatures. Q: What is formed when hot lava cools? Choices: - hydrogen crystals - lava rock - magma crystals - mineral crystals A:
A: mineral crystals
Question: Answer the following question given this paragraph: may not be able to use vision as their primary sense to find food. Instead, they are more likely to use taste or chemical cues to find prey. Wetlands Wetlands are environments in which the soil is either permanently or periodically saturated with water. Wetlands are different from lakes because wetlands are shallow bodies of water whereas lakes vary in depth. Emergent vegetation consists of wetland plants that are rooted in the soil but have portions of leaves, stems, and flowers extending above the water's surface. There are several types of wetlands including marshes, swamps, bogs, mudflats, and salt marshes (Figure 44.25). The three shared characteristics among these typeswhat makes them wetlandsare their hydrology, hydrophytic vegetation, and hydric soils. Q: There are several types of wetlands including marshes, swamps, bogs, mudflats, and salt marshes. the three shared characteristics among these typeswhat makes them wetlandsare their hydrology, hydrophytic vegetation, and this? Choices: - stibnite soils - sandy soils - niya soils - hydric soils A:
Answer: hydric soils

Answer the following question given this paragraph: Biochemical compounds are carbon-based compounds that make up living organisms. There are four main classes of biochemical compounds: carbohydrates, proteins, lipids, and nucleic acids. The classes have different structures and functions. Q: Living organisms are made up of what type of carbon-based compounds? Choices: - microbial - biophysical - synthetic - biochemical A:
**Answer**
biochemical

Answer the following question given this paragraph: Over 99 percent of all species that ever lived on Earth have gone extinct. Five mass extinctions are recorded in the fossil record. They were caused by major geologic and climatic events. Evidence shows that a sixth mass extinction is occurring now. Unlike previous mass extinctions, the sixth extinction is due to human actions. Q: What percentage of all species that ever lived on earth have gone extinct? Choices: - 25% - 50% - 93 % - 99% A:
**Answer**
99%
