<span>The correct answer is c. crenellation. The Colosseum has all three Greek orders (Doric, Ionic, and Corinthian) in its columns, it has many arches (think semicircular openings), and it has a post-and-lintel system (in which vertical elements -- like columns -- hold up horizontal elements, with large spaces between these two elements -- like arches). However, the Colosseum does not have crenellation, which is a battlement often seen on castles. A crenellation is a low protective wall on the roof of a building, with repetitive, squared openings from which people could shoot intruders. </span>

These two monosaccharides are glucose and fructose. Because of the sucrose molecule structure we can make all kinds of candy just using sugar and a liquid, and sometimes a bit of fat. When you heat the sucrose molecule to the right temperature it breaks apart and forms caramel.
