the presence of which element would indicate that a star is going through a high - mass star life cycle as opposed to a low - mass star life cycle?\no hydrogen\no carbon\no helium\no iron
Answer
Brief Explanations:
In a high - mass star life cycle, through successive nuclear fusion reactions, elements are built up until iron is formed. Low - mass stars do not reach the stage of producing iron. Hydrogen, carbon, and helium are produced in both low - mass and high - mass star life cycles at different stages, but iron is a key indicator of a high - mass star life cycle as its formation signals the end of the star's ability to produce energy through fusion and leads to a supernova explosion.
Answer:
D. iron
