Answer the following question given this paragraph: Farther from the heart, where the surge of blood has dampened, the percentage of elastic fibers in an artery's tunica intima decreases and the amount of smooth muscle in its tunica media increases. The artery at this point is described as a muscular artery. The diameter of muscular arteries typically ranges from 0.1 mm to 10 mm. Their thick tunica media allows muscular arteries to play a leading role in vasoconstriction. In contrast, their decreased quantity of elastic fibers limits their ability to expand. Fortunately, because the blood pressure has eased by the time it reaches these more distant vessels, elasticity has become less important. Notice that although the distinctions between elastic and muscular arteries are important, there is no "line of demarcation" where an elastic artery suddenly becomes muscular. Rather, there is a gradual transition as the vascular tree repeatedly branches. In turn, muscular arteries branch to distribute blood to the vast network of arterioles. For this reason, a muscular artery is also known as a distributing artery. Q: The thick tunica media allows muscular arteries to play a leading role in what? Choices: - inhibition - vasodilation - accumulation - vasoconstriction A:
vasoconstriction
Answer the following question given this paragraph: Blizzards are dangerous storms. The wind may blow the snow into deep drifts. Along with the poor visibility, the snow drifts make driving risky. The wind also makes cold temperatures more dangerous. The greater the wind speed, the higher the windchill. Windchill is what the temperature feels like when the wind is taken into account. It depends on air temperature and wind speed ( Figure below ). Higher windchill will cause a person to suffer frostbite and other harmful effects of cold sooner than if the wind isn't blowing. Q: What weather term describes what the temperature feels like when the wind is taken into account? Choices: - windshield - freezing point - humidity - windchill A:
windchill
Q: Answer the following question given this paragraph: Electromagnetic radiation from the sun reaches Earth across space. It strikes everything on Earth's surface, including these volleyball players. Q: What type of radiation from the sun reaches earth across space striking everything on earth's surface? Choices: - particle - static - seismic - electromagnetic A:
A: electromagnetic
Question: Answer the following question given this paragraph: Types of friction include static friction, sliding friction, rolling friction, and fluid friction. Fluid friction with air is called air resistance. Q: What is fluid friction with air called? Choices: - buoyancy - wind resistance - gravity - air resistance A:
Answer: air resistance

Answer the following question given this paragraph: The lithosphere is composed of both the crust and the uppermost mantle. The lithosphere is a brittle, rigid solid. It is easily cracked or broken. Q: Besides the uppermost mantle, what else is the lithosphere composed of? Choices: - surface - outer core - inner core - crust A:
**Answer**
crust

Answer the following question given this paragraph: In many species display behaviors, rather than actual physical attacks, are used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands. Q: How do the male gorillas show display behaviors? Choices: - food gathering - vocalization - spontaneous mutation - showing aggression A:
**Answer**
showing aggression
