3m - 3 divided by 3 for m=8

Either 7 or 23 - read note

Step-by-step explanation:

Substitute m for 8.

*Note: I'm not sure if anything is in parentheses so there are two possible answers depending on whether you want it done left to right or by order of operations*

Left to Right:

3(8) - 3 ÷ 3

24 - 3 ÷ 3

21 ÷ 3

7

Order of Operations:

3(8) - 3 ÷ 3

24 - 3 ÷ 3

24 - 1

23

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.
