Q: Answer the following question given this paragraph: Birds have air sacs that store inhaled air and push it into the lungs like bellows. This keeps the lungs constantly filled with oxygenated air. The lungs also contain millions of tiny passages that create a very large surface area for gas exchange with the blood (see Figure below ). Q: Birds have air sacs that store inhaled air and push it into their what? Choices: - beaks - bones - abdomens - lungs A:
A: lungs
Question: Answer the following question given this paragraph: Technology evolves as new materials, designs, and processes are invented. Q: Said to go hand-in-hand with science, what evolves as new materials, designs, and processes are invented? Choices: - invention - industry - biology - technology A:
Answer: technology

Answer the following question given this paragraph: To physically limit radiation doses, we use shielding, increase the distance from a source, and limit the time of exposure. Figure 32.10 illustrates how these are used to protect both the patient and the dental technician when an x-ray is taken. Shielding absorbs radiation and can be provided by any material, including sufficient air. The greater the distance from the source, the more the radiation spreads out. The less time a person is exposed to a given source, the smaller is the dose received by the person. Doses from most medical diagnostics have decreased in recent years due to faster films that require less exposure time. Q: Shielding should be used when receiving x-rays to limit exposure to what potentially harmful form of energy? Choices: - pollution - convection - evaporation - radiation A:
**Answer**
radiation
