Q: Answer the following question given this paragraph: An alloy is a mixture of a metal with one or more other elements. The other elements may be metals, nonmetals, or both. An alloy is formed by melting a metal and dissolving the other elements in it. The molten solution is then allowed to cool and harden. Alloys generally have more useful properties than pure metals. Several examples of alloys are described and pictured below. You can learn about another alloythe amazing alloy called memory wireat the following URL. If you have braces on your teeth, you might even have this alloy in your mouth!. Q: What is a mixture of metal with one or more other elements? Choices: - an alkali metal - a halloid - a metalloid - an alloy A:
A: an alloy

Q: Answer the following question given this paragraph: Carbohydrates, proteins, and nucleic acids are large molecules (macromolecules) built from smaller molecules (monomers) through dehydration reactions. In a dehydration reaction, water is removed as two monomers are joined together. Q: In a dehydration reaction, what is removed as two monomers are joined together? Choices: - carbon - air - nitrogen - water A:
A: water

Q: Answer the following question given this paragraph: Figure 3.31 A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups. Carbon residues in the pentose are numbered 1 through 5 (the prime distinguishes these residues from those in the base, which are numbered without using a prime notation). The base is attached to the 1 position of the ribose, and the phosphate is attached to the 5 position. When a polynucleotide is formed, the 5 phosphate of the incoming nucleotide attaches to the 3 hydroxyl group at the end of the growing chain. Two types of pentose are found in nucleotides, deoxyribose (found in DNA) and ribose (found in RNA). Deoxyribose is similar in structure to ribose, but it has an H instead of an OH at the 2 position. Bases can be divided into two categories: purines and pyrimidines. Purines have a double ring structure, and pyrimidines have a single ring. Q: What kind of structure do purines have? Choices: - triple ring structure - single ring structure - helical stucture - double ring structure A:
A: double ring structure
