Answer the following question given this paragraph: Surface waves travel along the ground outward from an earthquake's epicenter. Surface waves are the slowest of all seismic waves. They travel at 2.5 km (1.5 miles) per second. There are two types of surface waves. Love waves move side-to-side, much like a snake. Rayleigh waves produce a rolling motion as they move up and backward ( Figure above ). Surface waves cause objects to fall and rise. They also cause objects to sway back and forth. These motions cause damage to rigid structures during an earthquake. Q: How many types of surface waves are there? Choices: - over a hundred - three - six - two A:
two

(Answer)
crystals
Ques: Answer the following question given this paragraph: Polysaccharides A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide (poly- = "many"). The chain may be branched or unbranched, and it may contain different types of monosaccharides. The molecular weight may be 100,000 daltons or more depending on the number of monomers joined. Starch, glycogen, cellulose, and chitin are primary examples of polysaccharides. Starch is the stored form of sugars in plants and is made up of a mixture of amylose and amylopectin (both polymers of glucose). Plants are able to synthesize glucose, and the excess glucose, beyond the plant's immediate energy needs, is stored as starch in different plant parts, including roots and seeds. The starch in the seeds provides food for the embryo as it germinates and can also act as a source of food for humans and animals. The starch that is consumed by humans is broken down by enzymes, such as salivary amylases, into smaller molecules, such as maltose and glucose. The cells can then absorb the glucose. Starch is made up of glucose monomers that are joined by 1-4 or 1-6 glycosidic bonds. The numbers 1-4 and 1-6 refer to the carbon number of the two residues that have joined to form the bond. As illustrated in Figure 3.9, amylose is starch formed by unbranched chains of glucose monomers (only 1-4 linkages), whereas amylopectin is a branched polysaccharide ( 1-6 linkages at the branch points). Q: A long chain of monosaccharides linked by glycosidic bonds is known as what? Choices: - sulfate - Fructose - polymers - polysaccharide A:
Ans: polysaccharide

Answer the following question given this paragraph: Both endocytosis and exocytosis are active transport processes. Q: Both endocytosis and ______ are active transport processes. Choices: - biosynthesis - proteolysis - cellular respiration - exocytosis A:
(A).
exocytosis
Ques:Answer the following question given this paragraph: The epidermis is the outer layer of skin, consisting of epithelial cells and little else (see Figure below ). For example, there are no nerve endings or blood vessels in the epidermis. The innermost cells of the epidermis are continuously dividing through mitosis to form new cells. The newly formed cells move up through the epidermis toward the skin surface, while producing a tough, fibrous protein called keratin . The cells become filled with keratin and die by the time they reach the surface, where they form a protective, waterproof layer called the stratum corneum . The dead cells are gradually shed from the surface of the skin and replaced by other cells. Q: What is the name of the outer layer of skin? Choices: - endodermis - hypodermis - the dermis - the epidermis A:

Ans:the epidermis
Ques: Answer the following question given this paragraph: Note: Atomic mass is given to three decimal places, if known. Now that we understand that atoms have mass, it is easy to extend the concept to the mass of molecules. The molecular mass is the sum of the masses of the atoms in a molecule. This may seem like a trivial extension of the concept, but it is important to count the number of each type of atom in the molecular formula. Also, although each atom in a molecule is a particular isotope, we use the weighted average, or atomic mass, for each atom in the molecule. For example, if we were to determine the molecular mass of dinitrogen trioxide, N2O3, we would need to add the atomic mass of nitrogen two times with the atomic mass of oxygen three times:. Q: What is the sum of the masses of the atoms in a molecule? Choices: - compound mass - mass effect - atomic energy - molecular mass A:
Ans:
molecular mass
