Q: Answer the following question given this paragraph: The atmosphere has layers. The layers correspond with how temperature changes with altitude. By understanding the way temperature changes with altitude, we can learn a lot about how the atmosphere works. Q: The layers of the atmosphere correspond with what changes with altitude? Choices: - friction - nitrogen - oxygen - temperature A:
A: temperature

Q: Answer the following question given this paragraph: When ordered by atomic number, the discrepancies within Mendeleev's table disappeared. Tellurium has an atomic number of 52, while iodine has an atomic number of 53. So even though tellurium does indeed have a greater atomic mass than iodine, it is properly placed before iodine in the periodic table. Mendeleev and Moseley are credited with being most responsible for the modern periodic law : When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties. The result is the periodic table as we know it today. Each new horizontal row of the periodic table corresponds to the beginning of a new period because a new principal energy level is being filled with electrons. Elements with similar chemical properties appear at regular intervals, within the vertical columns called groups . Q: Each new horizontal row of the periodic table corresponds to the beginning of a new period because a new principal energy level is being filled with what? Choices: - protons - photons - neutrons - electrons A:
A: electrons

Q: Answer the following question given this paragraph: Nucleic acids are one of four classes of biochemical compounds. (The other three classes are carbohydrates, proteins, and lipids. ) Nucleic acids include RNA (ribonucleic acid) as well as DNA (deoxyribonucleic acid). Both types of nucleic acids contain the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus. Q: Rna and dna are types of what biochemical compounds containing the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus? Choices: - hormones - nitrous acids - amino acids - nucleic acids A:
A: nucleic acids

Q: Answer the following question given this paragraph: An object's kinetic energy is the energy due to motion. Kinetic energy can be defined mathematically as. Q: An object's energy due to motion is known as? Choices: - residual energy - inertia - thermodynamic energy - kinetic energy A:
A: kinetic energy
