Q: What is the most important element to life? Read this paragraph and choose the correct option from the provided answers: Carbon is the most important element to life. Without this element, life as we know it would not exist. As you will see, carbon is the central element in compounds necessary for life-organic compounds. These compounds include carbohydrates, lipids, proteins and nucleic acids. Choices: - oxygen - hydrogen - nitrogen - carbon A:
**Answer**
carbon

Q: Respiration cycles the organic carbon into which gas? Read this paragraph and choose the correct option from the provided answers: Figure 46.15 Carbon dioxide gas exists in the atmosphere and is dissolved in water. Photosynthesis converts carbon dioxide gas to organic carbon, and respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized. Volcanic activity and, more recently, human emissions, bring this stored carbon back into the carbon cycle. (credit: modification of work by John M. Evans and Howard Perlman, USGS). Choices: - liquid dioxide - phosphorus dioxide - oxygen - carbon dioxide A:
**Answer**
carbon dioxide

*Question*
Q: Extended stays in zero gravity are not healthy for human beings. thus, for the comfort of the astronauts, the station is rotated so that the astronauts feel there is what? Read this paragraph and choose the correct option from the provided answers: A space station was established far from the gravitational field of Earth. Extended stays in zero gravity are not healthy for human beings. Thus, for the comfort of the astronauts, the station is rotated so that the astronauts feel there is an internal gravity. The rotation speed is such that the apparent acceleration of gravity is . The direction of rotation is counter-clockwise. If the radius of the station is , what is its rotational speed, ?. Choices: - revealed gravity - still gravity - Fixed Gravity - internal gravity A:
**Answer**
internal gravity
