A species of frog lives in a forest. A snake species moves to the ecosystem where the frogs live and begins to hunt the frogs. U
sing your understanding of natural selection, what is the most likely explanation of what will happen to the frog population when the snakes, who
are predators and will hunt the frogs, move into the ecosystem?
O A. Some of the frogs would try to develop new traits to avoid the predator and pass those on traits to offspring, and the other frogs
would die.
OB. All of the frogs would try to develop new traits to be able to avoid the predator, and they will all survive and pass on their new
traits to offspring.
OC. The frogs that were born with traits that allow them to avoid the snake would be more likely to survive and reproduce, and the
frogs that are not would be less likely to survive and reproduce.
o D. Since all of the frogs have identical traits, they would all be equally good or bad at avoiding the snake and so they would all survive
and reproduce or they all would die.
The formation of a phosphodiester bond between adjacent nucleotides is catalyzed by the DNA polymerases. They do this efficiently only if the incoming base on the incoming nucleoside triphosphate is complementary to the base on the template strand and can bind efficiently.
