The Pair of lines a1x+b1y+c1 =0 and a2x+b2y+c2=0 are intersecting lines then the ratio of their coefficients is : a. a1/a2≠b1/b2

b. a1/a2=b1/b2≠c1/c2

c. a1/a2=b1/b2=c1/c2

d. a1/a2=b1/b2​

d.a1/a2=b1/b2

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.
