Question

which factors affect natural selection?
inheritance, isolation, adaptation
variation, overpopulation, adaptation
isolation, overpopulation, speciation
variation, inheritance, speciation

Explanation:

Natural selection is influenced by variation (differences among individuals), overpopulation (more individuals than resources can support), and adaptation (traits that help survival and reproduction). Inheritance is important for passing on traits but not a direct factor in the process of natural - selection itself. Isolation and speciation are related to the formation of new species and not primary factors of natural selection.

Answer:

variation, overpopulation, adaptation
