Q: In atherosclerosis, thickening of an arterial wall due to this can restrict blood flow through the artery? Read this paragraph and choose the correct option from the provided answers: Choices: - low blood pressure - high blood pressure - digestion - plaque formation A:
plaque formation

Q: Any sample of matter that has the same physical and chemical properties throughout the sample is called what? Read this paragraph and choose the correct option from the provided answers: Elements and Compounds Any sample of matter that has the same physical and chemical properties throughout the sample is called a substance. There are two types of substances. A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is acompound (Figure 1.2 "The General Steps of the Scientific Method"). Water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe. In contrast, scientists have identified tens of millions of different compounds to date. Choices: - element - molecule - type - substance A:
substance

Q: When a metal is oxidized and a nonmetal is reduced in a redox reaction, what is the resulting compound called? Read this paragraph and choose the correct option from the provided answers: There are many other examples of redox reactions in which two neutral elements combine to make a compound. These often take the form of a metal being oxidized and a nonmetal being reduced, resulting in an ionic compound. Two nonmetallic elements can also undergo a redox reaction of this type, in which the less electronegative element is oxidized and the more electronegative element is reduced. Choices: - soluble compound - alloy - magnetic compound - ionic compound A:
ionic compound

Q: What type of scale is the richter scale? Read this paragraph and choose the correct option from the provided answers: 7. Like the Richter scale, the moment magnitude scale is logarithmic. The 2011 Tohoku earthquake in Japan was 9.0 and did tremendous damage. A few months earlier, an 8.8 struck Chile and did much less damage. Why?. Choices: - dimensional - algorithmic - asymmetric - logarithmic A:
logarithmic
