← ScienceWhich risk increases during a stellar nucleosynthesis event with insufficient convective mixing?
A)Unstable isotope concentration increases rapidly✓
B)Alpha particle emission rate accelerates subtly
C)Binding energy per nucleon diminishes predictably
D)Gravitational collapse decelerates unexpectedly slowly
💡 Explanation
When convective mixing is lacking, synthesized isotopes accumulate locally within a star, so neutron capture proceeds at varying rates through different areas; therefore, unstable isotope concentration will increase locally rather than achieving even distributions.
