When factored completely the expression p^4-81 is equivalent to

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

(3x-8) or (3x+8)

step-by-step explanation:

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.
