Less blood can flow through it than the normal artery. Q: What fatty material inside arteries can restrict blood flow in the artery? Choices: - marble - collagen - cholesterol - plaque A:
plaque
Answer the following question given this paragraph: In saturated fatty acids, there are only single bonds between carbon atoms. As a result, the carbons are saturated with hydrogen atoms. Saturated fatty acids are found in fats. Fats are solid lipids that animals use to store energy. Q: What kind of bonds are there between carbon atoms in saturated fatty acids? Choices: - electrical - double - chemical - single A:
single
Q: Answer the following question given this paragraph: Sexual reproduction combines gametes from two parents. Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells. When two gametes come together at fertilization, the normal amount of chromosomes results. Gametes are produced by a special type of cell division known as meiosis . Meiosis contains two rounds of cell division without DNA replication in between. This process reduces the number of chromosomes by half. Q: What is the term for reproductive cells, such as sperm and egg? Choices: - spores - nucleus - parasites - gametes A:
A: gametes
Question: Answer the following question given this paragraph: Lead is still widely used in car batteries. In recent years, battery recycling is becoming very common - about 98% of car batteries a recycled today. The used batteries go to a processing plant where they are crushed and placed in a tank. The lead sinks to the bottom and can be separated, melted and used again. Plastic materials float to the top, are separated, and melted. The plastic can then be used in a number of applications. The battery acids are treated with chemicals to neutralize them before they are disposed of. Q: What substances in a car battery can be melted and recycled? Choices: - lead and steel - lead and sodium - steel and sodium - lead and plastic A:
Answer: lead and plastic

Answer the following question given this paragraph: The theory of climate change is very new. In fact, scientists don't even call it a theory. But it meets the requirements. These are the things we know: (1) average global temperatures are rising, (2) greenhouse gases trap heat in the atmosphere, (3) CO 2 is released into the atmosphere when fossil fuels are burned, (4) CO 2 is a greenhouse gas, (5) more CO 2 in the atmosphere traps more heat so global temperature is rising. No information contradicts this theory, although some details have not been worked out. The theory is very effective at predicting future events, which are already taking place. This idea will be explored in detail in the chapter Atmospheric Processes . Q: Which theory helps predict future events in weather? Choices: - expected change theory - future weather theory - carbon change theory - climate change theory A:
(Answer)
climate change theory
