Which of these systems of linear equations has an infinite number of solutions? 3 x minus 8 y = 21. 6 x minus 16 y = 46. 3 x + 6 y = 22. 6 x + 12 y = 44. 5 x + 7 y = 24. 10 x minus 14 y = 48. 5 x minus 9 y = 20. 10 x + 18 y = 40.

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.
