Answer the following question given this paragraph: Within a group, the ionization energy decreases as the size of the atom gets larger. On the graph, we see that the ionization energy increases as we go up the group to smaller atoms. In this situation, the first electron removed is farther from the nucleus as the atomic number (number of protons) increases. Being farther away from the positive attraction makes it easier for that electron to be pulled off. Q: Within a group, the ionization energy decreases as the size of the atom gets what? Choices: - brighter - smaller - lighter - larger A:
larger

Answer the following question given this paragraph: Modern reptiles live in many different habitats. They can be found on every continent except Antarctica. Q: Modern members of what broad animal group live in many different habitats and are found on every continent except antarctica? Choices: - arachnids - amphibians - parasites - reptiles A:
reptiles

Answer the following question given this paragraph: The mRNA is divided into three-base segments called codons. A codon is the segment of nucleotides that codes for an amino acid, or for a start or stop signal. There are 64 codons. Q: What is the total number of codons? Choices: - 45 - 51 - 68 - 64 A:
64

Answer the following question given this paragraph: Higher pressures increase the solubility of gases. You are probably familiar with this concept as it relates to carbonated beverages. Before opening the container, the inside is pressurized, so a large amount of CO 2 is dissolved in the liquid. After opening, the pressure decreases (to the ambient pressure), so the solubility of CO 2 drops, causing it to bubble out of solution. Because they are not compressible like gases, solid and liquid solutes do not have noticeable changes in solubility at different external pressures. Q: Higher pressures increase the solubility of what? Choices: - molecules - fuels - bases - gases A:
gases
