How do you do this and show me the scratch work on how you got it.

Well I answered it

Step-by-step explanation:

So first thing you are going to do is add, so we are going to use PEMDAS

add the 5+4 and you get 9 then we're going to take that 7 and add the 9 and 7 so that gives us 16 now the 11² so that means we are doing 11 two times i think so then 11 times 2 is 22 take that 16 and subtract so 22 take away 16 is 5 now idk what to do with the (4) and (3) at the bottom i hope this helped and i think this is what you have to do if not please tell me what grade this is so i know

40% off the regular price is the correct answer.

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.
