Question

1. why do some stars have more elements than other stars? note: there are multiple correct answers.

Explanation:

Stars' elemental abundances are related to their mass and age. More - massive stars can undergo more nuclear - fusion processes to create heavier elements. Older stars may have incorporated material from previous stellar generations, increasing their elemental diversity.

Answer:

1. Mass: More - massive stars can create heavier elements through nuclear fusion.
2. Age and Stellar Generation: Older stars may have accumulated material from earlier stellar explosions and generations, enriching their elemental composition.
