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 force between them if the distance between them is doubled is a. F/4
Explanation:
To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
The equation can be written as, where k is the Coulomb constant, are the point charges, and r is the distance between these two point charges.
To find the answer to this question, just substitute 2r in the place of r hence, you will get as the new force when the distance is doubled.
