Final answer:
Atoms that make up puppies come from particles like electrons, protons, and neutrons that were separated from the sun before the formation of the Earth.
Step-by-step explanation:
The atoms that make up the puppies come from different sources. Before the formation of the Earth, particles like electrons, protons, and neutrons were separated from the sun. These particles combined to form atoms or elements, and there are currently 93 different elements found in the Earth's crust. The atoms that make up living beings, including puppies, ultimately originated from these particles.
