Please help me answer Number 8. Needed ASAP for school. Will give Brainliest

[Step 1] Put data in order least to greatest

-> Data is already in order, fantastic!

[Step 2] Find the medium of all the data

-> We will find the middle value

-> See attached, in black

-> The value is 7.5

[Step 3] Find the medium of our halves

-> We will find the middle value of each of the halves

-> See attached, in white

-> For this, the value of the first quartile it is 3.5

-> For the, the value of the third quartile it is 9

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

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.
