Would Y + X be YX or XY?

Step-by-step explanation:

Terms obey the associative property of multiplication - that is, xy and yx are like terms, as are xy2 and y2x.

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.
