Answer the following question given this paragraph: solution. In addition, sucrose does not undergo reactions that are typical of aldehydes and ketones. Therefore, sucrose is a nonreducing sugar. The hydrolysis of sucrose in dilute acid or through the action of the enzyme sucrase(also known as invertase) gives an equimolar mixture of glucose and fructose. This 1:1 mixture is referred to as invert sugar because it rotates plane-polarized light in the opposite direction than sucrose. The hydrolysis reaction has several practical applications. Sucrose readily recrystallizes from a solution, but invert sugar has a much greater tendency to remain in solution. In the manufacture of jelly and candy and in the canning of fruit, the recrystallization of sugar is undesirable. Therefore, conditions leading to the hydrolysis of sucrose are employed in these processes. Moreover, because fructose is sweeter than sucrose, the hydrolysis adds to the sweetening effect. Bees carry out this reaction when they make honey. The average American consumes more than 100 lb of sucrose every year. About twothirds of this amount is ingested in soft drinks, presweetened cereals, and other highly processed foods. The widespread use of sucrose is a contributing factor to obesity and tooth decay. Carbohydrates such as sucrose, are converted to fat when the caloric intake exceeds the body's requirements, and sucrose causes tooth decay by promoting the formation of plaque that sticks to teeth. Q: Sucrose does not undergo reactions that are typical of aldehydes and ketones, therefore it is a nonreducing what? Choices: - wheat - juice - salt - sugar A:
sugar

Answer the following question given this paragraph: Carbon sequestration is any way of removing carbon dioxide from the atmosphere and storing it in another form. Carbon is sequestered naturally by forests. Trees take in carbon dioxide for photosynthesis. Artificial methods of sequestering carbon underground are being researched. Q: What term refers to any method of removing carbon dioxide from the atmosphere and storing it in another form? Choices: - carbon footprint - carbon metamorphosis - carbon transfer - carbon sequestration A:
(Answer)
carbon sequestration
Ques: 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:
Ans: double ring structure

Answer the following question given this paragraph: The distribution of darts on a dartboard shows the difference between accuracy and precision. Q: What does the distribution of darts on a dartboard shows the difference between? Choices: - production and precision - Aim and precision - equilibrium and precision - accuracy and precision A:
(A).
accuracy and precision
Ques:Answer the following question given this paragraph: A: The discovery of particles smaller than atoms doesn't mean that we should scrap the entire theory. Atoms are still known to be the smallest particles of elements that have the properties of the elements. Also, it is atomsnot particles of atomsthat combine in fixed proportions in compounds. Instead of throwing out Dalton's theory, scientists have refined and expanded on it. Q: What are the smallest particles of elements that maintain their unique properties? Choices: - protons - molecules - electrons - atoms A:

Ans:atoms
Question: Answer the following question given this paragraph: Figure 1.18 An atomic clock such as this one uses the vibrations of cesium atoms to keep time to a precision of better than a microsecond per year. The fundamental unit of time, the second, is based on such clocks. This image is looking down from the top of an atomic fountain nearly 30 feet tall! (credit: Steve Jurvetson/Flickr). Q: The fundamental unit of time, the second, is based on what type of clock? Choices: - quantum clock - eternal clock - gravity clock - atomic clock A:
Answer:
atomic clock
