Choose Yes or No to tell whether the symbol will be reversed when the variable is isolated in each inequality. -10.5 < 3a b/6 <_ 7 -4.5c > 9 -21/5 <_ -5/2d

answer: just subtact the units and then add the non negative : happy to

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.  

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
