In the diagram below, segment MN is the image of segment AB after a dilation with a center at point C. Which of the following ratios would represent the scale factor? 1. AB/BC
2. AB/MN
3. AM/CM
4. CN/CB

no this is a nonlinear negative

i got 10.28 but that rounds up to 10.3

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.  

thats not a system of equations, that is a solution
