Question: Answer the following question given this paragraph: A unique feature of echinoderms is their water vascular system . This is a network of canals that extend along each body part. In most echinoderms, the canals have external projections called tube feet (see Figure below ). The feet have suckers on the ends. Muscle contractions force water into the feet, causing them to extend outward. As the feet extend, they attach their suckers to new locations, farther away from their previous points of attachment. This results in a slow but powerful form of movement. The suckers are very strong. They can even be used to pry open the shells of prey. Q: What makes echinoderms force water into the feet and move forward? Choices: - spring contractions - vacuum contractions - field contractions - muscle contractions A:
Answer: muscle contractions

Answer the following question given this paragraph: Radon is also radioactive and can easily be inhaled into the lungs. Over time, this internal radon exposure can lead to the development of lung cancer. The incidence of lung cancer in smokers exposed to radon is much higher than that in non-smokers exposed to radon since smoking has already produced some lung damage, and the radon simply makes the damage worse. Radon exposure is highest in homes lacking good air circulation to move the gas out of the residence. There are a number of inexpensive approaches to decreasing your exposure to radon. A good start is to test your living area for radon with a radon test kit. Q: Smoking increases the risk of cancer from what radioactive gas that can also be detected with a test kit for your home? Choices: - arsenic - carbon monoxide - carbon dioxide - radon A:
**Answer**
radon
