Answer the following question given this paragraph: Q: The second shell holds a maximum of how many electrons? Choices: - 9 - 12 - 6 - 8 A:
8
Answer the following question given this paragraph: The order of bases in nucleic acids is highly significant. The bases are like the letters of a four-letter alphabet. These "letters" can be combined to form "words. " Groups of three bases form words of the genetic code . Each code word, called a codon, stands for a different amino acid. A series of many codons spells out the sequence of amino acids in a polypeptide or protein ( Figure below ). In short, nucleic acids contain the information needed for cells to make proteins. This information is passed from a body cell to its daughter cells when the cell divides. It is also passed from parents to their offspring when organisms reproduce. Q: Nucleic acids contain the information needed for cells to make what? Choices: - metabolytes - lipids - protons - proteins A:
proteins
Q: Answer the following question given this paragraph: The Earth is divided into many plates. These plates move around on the surface. The plates collide or slide past each other. One may even plunge beneath another. Plate motions cause most geological activity. This activity includes earthquakes, volcanoes, and the buildup of mountains. The reason for plate movement is convection in the mantle. Earth is the only planet that we know has plate tectonics. Q: What is the only planet we know that has plate techtonics? Choices: - Saturn - Mars - Jupiter - earth A:
A: earth
Question: Answer the following question given this paragraph: Alpha and beta decay occur when a nucleus has too many protons or an unstable ratio of protons to neutrons. When the nucleus emits a particle, it gains or loses one or two protons, so the atom becomes a different element. Gamma decay, in contrast, occurs when a nucleus is in an excited state and has too much energy to be stable. This often happens after alpha or beta decay has occurred. Because only energy is emitted during gamma decay, the number of protons remains the same. Therefore, an atom does not become a different element during this type of decay. Q: Alpha and beta decay occur when a nucleus has too many protons or an unstable ratio of what? Choices: - electrons to neutrons - atoms to neutrons - nucleus to neutrons - protons to neutrons A:
Answer: protons to neutrons

Answer the following question given this paragraph: All living cells are surrounded by a cell membrane. Plant cells (Figure 17.3 "An Idealized Plant Cell") and animal cells (Figure 17.4 "An Idealized Animal Cell") contain a cell nucleus that is also surrounded by a membrane and holds the genetic information for the cell. (For more information about genetics and DNA, see Chapter 19 "Nucleic Acids". ) Everything between the cell membrane and the nuclear membraneincluding Saylor URL: http://www. saylor. org/books. Q: What part of the cell is surrounded by a membrane and holds the genetic information for the cell? Choices: - cell wall - upper - lower - nucleus A:
**Answer**
nucleus
