-17k=-204 (one step equation )

x=-12

Step-by-step explanation:

x=204/-17

shift .the negative sign

x= -204/17

x=-12

answer: .75 km

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.
