Polypropylene is stiffer than polyethylene is in plastic utensils and some other types of containers. Q: What is the option to remove kidney stones other than surgery? Choices: - pump treatments - skin treatments - glandular treatments - ultrasound treatments A:

Answer the following question given this paragraph: Q: During metamorphosis, most salamander species go through what aquatic stage on the way to becoming adults? Choices: - prophase - metaphase - anaphase - larval stage A:
larval stage
Q: Answer the following question given this paragraph: Chromosomal Alterations. Chromosomal alterations are major changes in the genetic material. Q: What term is used to describe major changes in the genetic material? Choices: - generational alterations - eukaryotic alterations - mutational alterations - chromosomal alterations A:
A: chromosomal alterations
Question: Answer the following question given this paragraph: Most musical instruments use resonance to amplify the sound waves and make the sounds louder. Resonance occurs when an object vibrates in response to sound waves of a certain frequency. In a musical instrument such as a guitar, the whole instrument and the air inside it may vibrate when a single string is plucked. This causes constructive interference with the sound waves, which increases their amplitude. Q: What happens do the sound during a resonance? Choices: - it becomes quieter - it dissipates - it echoes - amplified, it becomes louder A:
Answer: amplified, it becomes louder

Answer the following question given this paragraph: Basic to Bohr's model is the idea of energy levels. Energy levels are areas located at fixed distances from the nucleus of the atom. They are the only places where electrons can be found. Energy levels are a little like rungs on a ladder. You can stand on one rung or another but not between the rungs. The same goes for electrons. They can occupy one energy level or another but not the space between energy levels. Q: What are the areas located at fixed distances from the nucleus of the atom? Choices: - molar levels - atomic regions - orbit points - energy levels A:
**Answer**
energy levels

Answer the following question given this paragraph: wave functions can predict within a certain level of probability where an electron might be at any given time. The area where an electron is most likely to be found is called its orbital. Recall that the Bohr model depicts an atom's electron shell configuration. Within each electron shell are subshells, and each subshell has a specified number of orbitals containing electrons. While it is impossible to calculate exactly where an electron is located, scientists know that it is most probably located within its orbital path. Subshells are designated by the letter s, p, d, and f. The s subshell is spherical in shape and has one orbital. Principal shell 1n has only a single s orbital, which can hold two electrons. Principal shell 2n has one s and one p subshell, and can hold a total of eight electrons. The p subshell has three dumbbell-shaped orbitals, as illustrated in Figure 2.8. Subshells d and f have more complex shapes and contain five and seven orbitals, respectively. These are not shown in the illustration. Principal shell 3n has s, p, and d subshells and can hold 18 electrons. Principal shell 4n has s, p, d and f orbitals and can hold 32 electrons. Moving away from the nucleus, the number of electrons and orbitals found in the energy levels increases. Progressing from one atom to the next in the periodic table, the electron structure can be worked out by fitting an extra electron into the next available orbital. Q: What is the area where an electron is most likely to be found called? Choices: - neutron - proton - neucleus - orbital A:
(A).
