Answer the following question given this paragraph: The most common type of cancer in adult males is cancer of the prostate gland. The prostate gland is part of the male reproductive system. About one third of all cancers in men are prostate cancers. Q: What is the most common type of cancer in adult males? Choices: - lung - leukemia - stomach - prostate A:
prostate
Answer the following question given this paragraph: Fats are solid lipids that animals use to store energy. Q: What are solid lipids that animals use to store energy called? Choices: - steroids - cholesterol - hydrocortisol - fats A:
fats
Q: Answer the following question given this paragraph: Coal is a black or brownish-black rock that burns easily ( Figure below ). Most coal is sedimentary rock. The hardest type of coal, anthracite, is a metamorphic rock. That is because it is exposed to higher temperature and pressure as it forms. Coal is mostly carbon, but some other elements can be found in coal, including sulfur. Q: What element makes up the majority of coal? Choices: - iron - lead - silicon - carbon A:
A: carbon
Question: Answer the following question given this paragraph: A catalyst is a substance that increases the rate of a chemical reaction. The presence of a catalyst is one of several factors that influence the rate of chemical reactions. (Other factors include the temperature, concentration, and surface area of reactants. ) A catalyst isn't a reactant in the chemical reaction it speeds up. As a result, it isn't changed or used up in the reaction, so it can go on to catalyze many more reactions. Q: A catalyst can increase the rate of what, in general? Choices: - mechanicl reaction - carbon reaction - consumption reaction - chemical reaction A:
Answer: chemical reaction

Answer the following question given this paragraph: Summary Four quantities must be known for a complete physical description of a sample of a gas: temperature, volume, amount, and pressure. Pressure is force per unit area of surface; the SI unit for pressure is the pascal (Pa), defined as 1 newton per square meter (N/m2). The pressure exerted by an object is proportional to the force it exerts and inversely proportional to the area on which the force is exerted. The pressure exerted by Earth's atmosphere, called atmospheric pressure, is about 101 kPa or 14.7 lb/in.2 at sea level. Atmospheric pressure can be measured with abarometer, a closed, inverted tube filled with mercury. The height of the mercury column is proportional to atmospheric pressure, which is often reported in units ofmillimeters of mercury (mmHg), also called torr. Standard atmospheric pressure, the pressure required to support a column of mercury 760 mm tall, is yet. Q: What is the si unit for pressure? Choices: - watt - laurent - le - pascal A:
**Answer**
pascal
Answer the following question given this paragraph: Ribosomes are cellular substructures where proteins are synthesized. They contain about 65% rRNA and 35% protein, held together by numerous noncovalent interactions, such as hydrogen bonding, in an overall structure consisting of two globular particles of unequal size. Molecules of tRNA, which bring amino acids (one at a time) to the ribosomes for the construction of proteins, differ from one another in the kinds of amino acid each is specifically designed to carry. A set of three nucleotides, known as a codon, on the mRNA determines which kind of tRNA will add its amino acid to the growing chain. (For more information on sequences, see Section 19.4 "Protein Synthesis and the Genetic Code". ) Each of the 20 amino acids found in proteins has at least one corresponding kind of tRNA, and most amino acids have more than one. The two-dimensional structure of a tRNA molecule has three distinctive loops, reminiscent of a cloverleaf (Figure 19.11 "Transfer RNA"). On one loop is a sequence of three nucleotides that varies for each kind of tRNA. This triplet, called the anticodon, is complementary to and pairs with the codon on the mRNA. At the opposite end of the molecule is the acceptor stem, where the amino acid is attached. Figure 19.11 Transfer RNA Saylor URL: http://www. saylor. org/books.
