Which of the following equation would be solved for x by adding both sides and then multiplying both sides by 2

there isnt an equation.

1=1

1×2=1×2

2=2

x can only be the same thing as whats on the other side

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.  

step-by-step explanation:

mean or average is 40.6
