Where did the atoms that make up a newborn baby originally come from?
A
They were created spontaneously at the moment of the baby's conception.
B
They originated from chemical reactions occurring only on Earth after life began.
C
They were formed in stars through nuclear fusion before the formation of the solar system.
D
They were assembled by biological processes unique to humans.
Verified step by step guidance1
Understand the concept of atomic origin: Atoms are the building blocks of matter, and their origin is tied to processes in the universe, not specific biological events.
Learn about nuclear fusion in stars: Stars fuse lighter elements like hydrogen into heavier elements such as carbon, oxygen, and nitrogen through nuclear fusion. This process occurs over billions of years.
Recognize the role of supernovae: When massive stars reach the end of their life cycle, they explode in supernovae, dispersing these heavier elements into space, enriching the interstellar medium.
Connect the formation of the solar system: The solar system, including Earth, formed from a cloud of gas and dust containing these elements, which were produced by earlier generations of stars.
Understand biological assembly: The atoms formed in stars were later incorporated into molecules and structures through chemical and biological processes, eventually becoming part of living organisms, including humans.
