Answer the following question given this paragraph: Gases are also capable of dissolving in liquids. There are many examples of this in our everyday lives. For example, carbonated beverages contain dissolved carbon dioxide. We notice this when bubbles come out of solution when the beverage is opened. Another example is when oxygen from the air we breathe dissolves in our blood, where it is transported throughout the body. Fish and other aquatic organisms use gills to capture dissolved oxygen from their environments. Q: Fish and other aquatic organisms use gills to capture dissolved what? Choices: - food - sulfur - nitrogen - oxygen A:
oxygen

Answer the following question given this paragraph: Pictured below is a typical elliptical galaxy ( Figure below ). As you might have guessed, elliptical galaxies are elliptical, or egg-shaped. The smallest elliptical galaxies are as small as some globular clusters. Giant elliptical galaxies can contain over a trillion stars. Elliptical galaxies are reddish to yellowish in color because they contain mostly old stars. Q: What do you call egg-shaped galaxies, which are reddish to yellowish in color because they contain mostly old stars? Choices: - conical galaxies - irregular galaxies - spiral galaxies - elliptical galaxies A:
elliptical galaxies
