conclusion question #6

1. how is it possible for our human bodies to contain carbon and iron if nuclear fusion is only possible by stars or mimicked in nuclear power plants?

Explanation:

Elements like carbon and iron in human - bodies were produced in stars through nuclear fusion. When stars go through their life - cycles and eventually explode in supernovae, they release these elements into space. These elements then became part of the material that formed the Earth. Through the food chain and biological processes, they became incorporated into human bodies.

Answer:

Elements like carbon and iron were produced in stars, released in supernovae, became part of Earth's material, and were incorporated into human bodies through the food chain and biological processes.
