Answer the following question given this paragraph: Macroevolution is evolution over geologic time above the level of the species. One of the main topics in macroevolution is how new species arise. The process by which a new species evolves is called speciation . How does speciation occur? How does one species evolve into two or more new species?. Q: What is the term for evolution over geologic time above the level of the species? Choices: - mutation - speciation - microevolution - macroevolution A:
macroevolution
Answer the following question given this paragraph: The length traveled by an object moving in any direction or even changing direction is called distance. Q: The length that an object has travelled in one or multiple directions can also be called what? Choices: - axis - velocity - range - distance A:
distance
Q: Answer the following question given this paragraph: The type of eruption a volcano has depends on the type of magma in its chamber. Some eruptions are explosive. Some eruptions are quiet. All eruptions are amazing!. Q: The type of eruption a volcano has depends on the type of what in its chamber? Choices: - funnel - cavity - core - magma A:

Question: Answer the following question given this paragraph: Some of the most important animal behaviors involve mating. Mating is the pairing of an adult male and female to produce young. Adults that are most successful at attracting a mate are most likely to have offspring. Traits that help animals attract a mate and have offspring increase their fitness. As the genes that encode these traits are passed to the next generation, the traits will become more common in the population. Q: What is the pairing of an adult male to an adult female to produce young? Choices: - evolution - asexual reproduction - binary fission - mating A:
Answer: mating

Answer the following question given this paragraph: Animals such as bats and dolphins send out ultrasound waves and use their echoes, or reflected waves, to identify the locations of objects they cannot see. This is called echolocation. Animals use echolocation to find prey and avoid running into objects in the dark. You can see in the Figure below and also at the following URL how a bat uses echolocation to find insect prey. http://www. bsos. umd. edu/psyc/batlab/headaimmovies/nsf_challenge/nsf4. wmv. Q: What is the term for the method of sending out ultrasound waves to determine the locations of objects? Choices: - catabolism - magnetism - morphology - echolocation A:
**Answer**
echolocation
Q: Answer the following question given this paragraph: Much of the iron produced is refined and converted into steel. Steel is made from iron by removing impurities and adding substances such as manganese, chromium, nickel, tungsten, molybdenum, and vanadium to produce alloys with properties that make the material suitable for specific uses. Most steels also contain small but definite percentages of carbon (0.04%2.5%). However, a large part of the carbon contained in iron must be removed in the manufacture of steel; otherwise, the excess carbon would make the iron brittle. Q: Much of the iron produced is refined and converted into what? Choices: - plastic - wood - sugar - steel A:
A: steel
