Answer the following question given this paragraph: Carbon dioxide molecules consist of a central carbon atom bonded to 2 oxygen atoms. Q: Carbon dioxide molecules consist of a central carbon atom bonded to how many oxygen atoms? Choices: - one - four - three - two A:
two
Answer the following question given this paragraph: The smallest particle of an element that still has the properties of that element is the atom . Atoms actually consist of smaller particles, including protons and electrons, but these smaller particles are the same for all elements. All the atoms of an element are like one another, and are different from the atoms of all other elements. For example, the atoms of each element have a unique number of protons. Q: What is the smallest part of an element called? Choices: - core - neutron - nucleus - atom A:
atom
Q: Answer the following question given this paragraph: Chemical sedimentary rocks form when crystals precipitate out from a liquid. The mineral halite, also called rock salt, forms this way. You can make halite! Leave a shallow dish of salt water out in the Sun. As the water evaporates, salt crystals form in the dish. There are other chemical sedimentary rocks, like gypsum. Q: What forms when crystals precipitate out from a liquid? Choices: - liquid sedimentary rocks - plasma sedimentary rocks - plants sedimentary rocks - chemical sedimentary rocks A:
A: chemical sedimentary rocks
Question: Answer the following question given this paragraph: Normally, electric charge is transferred when electrons leave the outer orbits of the atoms of one body (leaving it positively charged) and move to the surface of another body (causing the new surface to gain a negative net charge). In a plasma all electrons are stripped from the atoms, leaving positively charged ions and free electrons. Q: What do extensive properties depend on the amount of? Choices: - experimental controls - sample temperature - independent variables - matter in a sample A:
Answer: matter in a sample

Answer the following question given this paragraph: Most turtle bodies are covered by a special bony or cartilaginous shell developed from their ribs. Q: Most turtle bodies are covered by a special bony or cartilaginous shell developed from their what? Choices: - spines - tails - fins - ribs A:
**Answer**
ribs
Q: Answer the following question given this paragraph: Seismograms contain a lot of information about an earthquake: its strength, length and distance. Wave height used to determine the magnitude of the earthquake. The seismogram shows the different arrival times of the seismic waves ( Figure below ). The first waves are P-waves since they are the fastest. S-waves come in next and are usually larger than P-waves. The surface waves arrive just after the S-waves. If the earthquake has a shallow focus, the surface waves are the largest ones recorded. Q: What three parameters do seismographs measure? Choices: - height, width and distance - aging , length and distance - trouble , length and distance - strength, length and distance A:
A: strength, length and distance
