The correct response is: Changes in the environment can act only on existing variations in a population.
Well, let me clown around with this question! When it comes to changes in the environment and variations, they actually go hand in hand like two jokers in a deck of cards. You see, changes in the environment can act on existing variations in a population, like when a clown car gets a fresh paint job. But wait, there's more! These changes in the environment can also influence the fitness of an organism, just like putting on the right clown shoes can make you a star at the circus. And don't forget, changes in the environment can even change which traits are advantageous, just like swapping out a red clown nose for a blue one. So, to sum it all up, the relationship between changes in the environment and variations is a funny dance that affects the survival and success of all living things.
The correct response is: Changes in the environment can act only on existing variations in a population.
The correct relationship between changes in the environment and variations is:
Changes in the environment can only cause new variations to appear (1 point).
When the environment changes, it can act as a selective pressure on existing variations within a population. In other words, it can favor certain traits or characteristics that are advantageous in the new environment. This selective pressure can result in the survival and reproduction of individuals with those advantageous traits, while individuals without those traits may be less successful in reproducing.
Over time, this process of natural selection can lead to changes in the genetic makeup of a population, as advantageous variations become more common and less advantageous ones decrease. These changes can be the result of both random mutations (which are random changes in the DNA) and the environment's influence on the fitness of certain traits.
Therefore, the relationship between changes in the environment and variations is that changes in the environment can cause new variations to appear, as well as influence the fitness and prevalence of existing variations.
