Answer the following question given this paragraph: A theory is constantly tested. If some data does not agree with the theory, the theory can be revised. If the theory cannot match the data, it is thrown out. That being said, sometimes a theory is well-established; it has a lot of evidence to back it up. A well-established theory is unlikely to be overthrown. It may just need to be modified a bit. But science does not prove anything beyond a shadow of a doubt. Q: In science, what is constantly tested, sometimes revised, sometimes thrown out and sometimes well-established? A:

OPTIONS:
- a technique
- a study
- a variable
- a theory

Answer: a theory

Problem: OPTIONS:
- ultraviolet radiation
- fluid radiation
- chemical radiation
- gamma radiation
Q: Answer the following question given this paragraph: Of the three basic types of emissions, gamma radiation has the highest penetrating power. Thick, high density materials (such as lead) are required to stop gamma emissions. The thickness of the shielding will determine the effectiveness of the protection offered by the lead. Q: Of the three basic types of emissions, which has the highest penetrating power? A:
Answer: gamma radiation

Problem:OPTIONS:
- exothermic
- hydrostatic
- autotrophic
- endothermic

Answer the following question given this paragraph: Endothermic reactions absorb energy from the surroundings as the reaction occurs. When 1 mol of calcium carbonate decomposes into 1 mol of calcium oxide and 1 mol of carbon dioxide, 177.8 kJ of heat is absorbed. The process is shown visually in Figure above (B). The thermochemical reaction is shown below. Q: What kind of reactions absorb energy from their surroundings as they occur? A:
****
A: endothermic

Answer the following question given this paragraph: Molar mass is equal to density multiplied by molar volume. Q: Molar mass is equal to density multiplied by what? A:
OPTIONS:
- molar energy
- molar weight
- molar gravity
- molar volume
molar volume

Answer the following question given this paragraph: Specialists are organisms that eat just one type of food. Birds that are specialists include ospreys, which eat only live fish. You can see an osprey in Figure below . The osprey's feet are very well-adapted for catching fish. Its eyes are also well-adapted for seeing fish under the water. Its beak is well suited for gripping and ripping into fish flesh. Ospreys are so well-adapted to catching fish that they can't catch anything else!. Q: What are organisms that eat just one type of food? A:
OPTIONS:
- gluttons
- hedonists
- devotees
- specialists

Answer:
specialists
