(8+4)to the second power +(18÷3)​

150

Step-by-step explanation:

(8+4)^2 + (18/3)

12^2 + (18/3)  First Evaluate (8+4)^2 and divide 18 by 3

144 + 6 Add

=150 <--- And 150 is your final answer :)

Side Note: When using powers it is the number times itself a certain amount of times. That is why we multiply 12 * 12.

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.
