Q: Answer the following question given this paragraph: Bacteria in food or water usually can be killed by heating it to a high temperature. Generally, this temperature is at least 71 C (160 F). Bacteria on surfaces such as countertops and floors can be killed with disinfectants, such as chlorine bleach. Bacterial infections in people can be treated with antibiotic drugs . These drugs kill bacteria and may quickly cure the disease. If you've ever had strep throat, you were probably prescribed an antibiotic to treat it. Q: What helps treat bacterial infections in people? A:

OPTIONS:
- respiratory drugs
- vaccines
- rest
- antibiotic drugs

A: antibiotic drugs

Q: Answer the following question given this paragraph: Note: Atomic mass is given to three decimal places, if known. Now that we understand that atoms have mass, it is easy to extend the concept to the mass of molecules. The molecular mass is the sum of the masses of the atoms in a molecule. This may seem like a trivial extension of the concept, but it is important to count the number of each type of atom in the molecular formula. Also, although each atom in a molecule is a particular isotope, we use the weighted average, or atomic mass, for each atom in the molecule. For example, if we were to determine the molecular mass of dinitrogen trioxide, N2O3, we would need to add the atomic mass of nitrogen two times with the atomic mass of oxygen three times:. Q: What is the sum of the masses of the atoms in a molecule? A:

OPTIONS:
- compound mass
- mass effect
- atomic energy
- molecular mass

A: molecular mass

Q: Answer the following question given this paragraph: The surface of Mars has volcanoes and canyons. There is a polar ice cap and channels that were once filled with water. Curiosity has found evidence of a flowing stream. Q: What two structures are found on mars? A:

OPTIONS:
- geysers and canyons
- Mountains and Creeks
- Trees and Canyons
- volcanoes and canyons

A:
volcanoes and canyons
