a. earth is very old.
b. everything has a predator.
c. organisms' characteristics are carried on dna.
d. more individuals are born than can live on available resources.
Answers
The correct answer should be D. More individuals are born than can live on available resource. The key idea behind it was that natural selection was survival of the fittest. The fittest could get to resources and avoid predators, while those who couldn't would die out. Eventually there would be an entire species of those who have the traits of those who were the fittest.
"C. Organisms' characteristics are carried
on DNA." would be the best fit, although this still isn't really the core idea behind natural selection, which is that animals survive based on how "fit" they are for their environment.
