Question

What relationship exists between changes in the environment and variations
Changes in the environment can act on existing variations in a population
Changes in the environment can only cause new variations to appear
Changes in the environment cannot influence the fitness of an organism
Changes in the environment cannot change which traits are advantageous

Answer 1

Changes in the environment can act on existing variations in a population and influence the fitness of an organism. This can result in certain traits becoming more advantageous while others become less advantageous, leading to natural selection and adaptation within a population. Additionally, changes in the environment can also cause new variations to appear through processes such as mutation and genetic recombination. Therefore, changes in the environment and variations in a population are closely interconnected and can have a significant impact on the evolution and survival of a species.
