Simplify −3x^3(−2x^2+4x−3)

Step-by-step explanation:

6x^5 - 12x^4 + 9x^3

(-3x^3*(-2x^2) - 3x^3(4x) - 3x^3(-3)

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
