What is natural selection? a process that selects variations that with survival and that spreads the variations to more offspring a process through which nature selects an individual within a population for extinction the difference in heritable traits within a population the process of nature that causes random variations to appear in the offspring of every generation

The right answer is a process that selects variations that help with survival and that spreads the variations to more offspring.

Natural selection is based on interindividual variability. It concerns traits affecting survival and reproductive success itself. The characters selected depend for the most part on the environment, the organisms, over generations, being better adapted to it (available food, predators, prey, competitors, climate, pollution, relief, etc.).

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
