One key point in Dalton's atomic theory was "Chemical reactions involve reorganization of the atoms - changes in the way they are bound together." Put that idea with the common phrase "you are what you eat." Now, which of the following best describes the connection between eating pizza and John Dalton's atomic theory?

1. Many of the components that make up pizza will soon become
part of your body, but you won't look like a pizza because the components will be broken into new fragments and later reassembled differently.2. Many of the components that make up pizza will soon become part of your cells, but you won't actually look like a pizza because the atoms in pizza change identities when the pizza is digested.3. The way the atoms in pizza are bound together is not affected by digestion - once inside you, the atoms in compounds remain connected. There are proteins, fats, and carbohydrates in pizza. The atoms in those compounds remain connected that way as they become part of your cells. Copyright © Houghton Mifflin Company. All rights reserved.2-8ANSWER
Choice 1explains that you are what you eat because the "what" is actually made up of atoms that are not destroyed during digestion. Many of the atoms in compounds that are found in pizza become rearranged with new connections and may become part of your cellular makeup. Copyright © Houghton Mifflin Company.
