What is the answer?

91

Step-by-step explanation:

We just have to put in the value of x into the equation.

  8 - 4[x - (2x² + 5)] + 3

= 8 - 4[3 - (2×3² + 5)] + 3

= 8 - 4[3 - (2×9 + 5)] + 3

= 8 - 4[3 - (18 + 5)] + 3

= 8 - 4(3 -23) + 3

= 8 - 4(-20) + 3

= 8 - (-80) + 3

= 8 + 80 + 3

= 91

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.
