Answer the following question given this paragraph: Atherosclerosis of arteries that supply the heart muscle is called coronary heart disease . This disease may or may not have symptoms, such as chest pain. As the disease progresses, there is an increased risk of heart attack. A heart attack occurs when the blood supply to part of the heart muscle is blocked and cardiac muscle fibers die. Coronary heart disease is the leading cause of death of adults in the United States. Q: What is the term for atherosclerosis of arteries that supply the heart muscle? Choices: - rapid heart disease - essential heart disease - cardiovascular disease - coronary heart disease A:
coronary heart disease
Answer the following question given this paragraph: The diversity of life on Earth today is the result of evolution. Life began on Earth at least 3.5 to 4 billion years ago, and it has been evolving ever since. At first, all living things on Earth were simple, single-celled organisms. Much later, the first multicellular organisms evolved, and after that, Earth's biodiversity greatly increased. Figure below shows a timeline of the history of life on Earth. You can also find an interactive timeline of the history of life at the link below. http://www. johnkyrk. com/evolution. html. Q: The diversity of life on earth today is the result of what? Choices: - spontaneous mutation - generation - mass extinction - evolution A:
evolution
Q: Answer the following question given this paragraph: The adult human skeleton has 206 bones, some of which are named below ( Figure below ). Bones are made up of living tissue. They contain many different types of tissues. Cartilage, a dense connective tissue, is found at the end of bones and is made of tough protein fibers. Cartilage creates smooth surfaces for the movement of bones that are next to each other, like the bones of the knee. Q: On what part of bones would you expect to find cartilage? Choices: - interior - marrow - exterior - end A:
A: end
Question: Answer the following question given this paragraph: Water flowing out of the ground at a spring may flow downhill and enter a stream. That's what happens to the water that flows out of Big Spring in Missouri. If the water from a spring can't flow downhill, it may spread out to form a pond or lake instead. Lake George in New York State, which is pictured in Figure below , is a spring-fed lake. The lake basin was carved by a glacier. Q: If water from a spring can't flow downwards, it can spread out to form one of 2 things. what are they? Choices: - lake or ocean - ocean or sea - ocean or river - pond or lake A:
Answer: pond or lake

Answer the following question given this paragraph: Boron neutron capture therapy is a potential treatment for many diseases. As the name implies, when boron10, one of the naturally occurring isotopes of boron, is bombarded with neutrons, it absorbs a neutron and emits an particle. Write a balanced nuclear reaction for this reaction. One advantage of this process is that neutrons cause little damage on their own, but when they are absorbed by boron-10, they can cause localized emission of alpha radiation. Comment on the utility of this treatment and its potential difficulties. Q: When boron10 absorbs a neutron, what does it emit? Choices: - calcium - light - proteins - particle A:
**Answer**
particle

Answer the following question given this paragraph: Distillation is an effective method to separate mixtures comprised of two or more pure liquids. Distillation is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated and the most volatile component vaporizes at the lowest temperature. The vapor passes through a cooled tube (a condenser), where it condenses back into its liquid state. The condensate that is collected is called distillate. Q: What is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated? Choices: - conduction - sterilization - dispersion - distillation A:
(Answer)
distillation
