Solve the equation -2/5x-9< 9/10

x> −99/4

Step-by-step explanation:

Add 9 to both sides. −2/5x−9+9< 9/10+9

Multiply both sides by 5/(-2).  (5/−2) * (−2/5x)<(5/−2)*(99/10)

x>−99/4

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.
