Answer the following question given this paragraph: The majority of the human genome is non-coding sequence. These sequences include regulatory sequences, and DNA with unknown functions. These sequences include tandem repeat elements known as satellite DNA , and transposons. Satellite DNA consists of very large arrays of tandemly repeating, non-coding DNA. The repeating units can be just a single base (a mono nucleotide repeat), two bases (a dinucleotide repeat), three bases (a trinucleotide repeat) or a much larger repeating unit. Some repeating units are several thousand base pairs long, and the total size of a satellite DNA segment can be several megabases without interruption. Q: What is the term for very large arrays of tandemly repeating, non-coding dna? Choices: - recombinant dna - models dna - addition dna - satellite dna A:
(A).
satellite dna

Answer the following question given this paragraph: Electrochemistry is the study of chemical processes that occur at the interface between an electron conductor, such as a wire, and a solution of electrolytes, which is often simply an ionic substance dissolved in water. Electrochemical processes involve a transfer of electrons between the wire and the solution. These reactions can be used to create electrical power, to purify metals, and to carry out a number of useful chemical transformations. Q: What processes involve a transfer of electrons between the wire and the solution? Choices: - radioactive - magnetic - thermal - electrochemical A:
(A).
electrochemical

Answer the following question given this paragraph: Solubility is normally expressed in g/L of saturated solution. However, solubility can also be expressed as the moles per liter. Molar solubility is the number of moles of solute in one liter of saturated solution. In other words, the molar solubility of a given compound represents the highest molarity solution that is possible for that compound. The molar mass of a compound is the conversion factor between solubility and molar solubility. Given that the solubility of Zn(OH) 2 is 4.2 10 -4 g/L, the molar solubility can be calculated as shown below:. Q: The conversion factor between solubility and molar solubility of a compound is known as what? Choices: - mass effect - stochastic mass - molar value - molar mass A:
(A).
molar mass
