which best illustrates a result of natural selection?\n○ a bat that is born with a wing that is missing the web\n○ dark-colored hares living in a snowy area\n○ mosquitoes that transmit disease to humans\n○ giraffes having increasingly longer necks over time

Answer

Brief Explanations:

Natural selection is the process where traits that improve survival and reproduction become more common in a population over generations.

  • A bat with a missing wing web is a random mutation, not a trait selected for survival.
  • Dark-colored hares in a snowy area are poorly camouflaged, so this trait would be selected against, not a result of natural selection.
  • Mosquitoes transmitting disease is a byproduct of their feeding, not a trait shaped by natural selection for survival/reproduction of the mosquitoes in this context.
  • Giraffes with longer necks could reach more food, so they survived and reproduced more, passing on the long-neck trait, leading to increasingly longer necks over time—this matches natural selection.

Answer:

giraffes having increasingly longer necks over time
