Given: 2x + 3y = 6. When x has a value of zero, the y value is 2.

0+6=6

Step-by-step explanation:

2x if x=0 would = 2x0=0 and 3y if y=2 3x2=6 so 0+6=6

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.
