Question

mutations are important because they bring about...
benefits for the individual, not for the population
genetic variation needed for a population to evolve
death of the organism in which they develop
hardey - weinberg equilibrium within a population

Explanation:

Mutations introduce new genetic material, creating genetic variation. This variation is essential for natural selection and evolution, as populations need diverse traits to adapt. The other options are incorrect: mutations don’t only benefit individuals (some are neutral/harmful), don’t always cause death, and Hardy-Weinberg equilibrium requires no mutations (so mutations disrupt it, not maintain it).

Answer:

B. genetic variation needed for a population to evolve
