Step 1. 3(3x − 4) = 8 + 2x + 5 step 2. 6x − 7 = 13 + 2x step 3. 6x − 2x = 13 + 7 step 4. 4x = 20 step 5. x = 5 in which step did the student first make an error and what is the correct step?
a. step 2, 9x − 12 = 13 + 2x
b. step 2, 9x − 4 = 2(6 + x + 3)
c. step 3, 6x + 2x = 13 + 7
d. step 3, 6x − 2x = 13 − 7

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

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.
