Solve the equation s - 12 = 20. ?​

s=32

Step-by-step explanation:

1. Move the constant to the right hand side and change it's sign so

s=20+12

2. Than calcuate s=20+12 which equals 32

so the solution is 32

it is b)

hope this : )

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.
