Rectangle ABCD has side lengths of 6 centimeters and 8 centimeters. Rectangle EFGH has side lengths of 9 centimeters and 12 centimeters. Determine the ratio of corresponding side lengths if ABCD is similar to EFGH. 1:3
2:3
3:1
3:2

2/3

Step-by-step explanation:

6/9=8/12=2/3

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.  

your answer is -9
