Meiosis. Sexual recombination. Crossing over. Independent assortment. Mutations.
The two MAIN sources would be genetic(sexual) recombination and mutations. Mutations allow for genetic variation, while genetic recombination allows for genetic shuffling. :)

The answer is A, population growth increases .
—Explanation—
•] The definition of limiting factor; anything that constrains a population's size and slows or stops it from growing.
•]Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.
•] So if the limiting factor is removed then the population begins to expand due to not having a factor that limits each species quantity.
