22=a(0-10)²+72

solve for me asap

Step-by-step explanation:

Good evening ,

a=-1/2

Step-by-step explanation:

22=a(-10)²+72

22=100a+72

22-72=100a

-50=100a

-1/2=a.

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.  

i agree because i see the other persons thinking is clear
