Yara multiplies and divides a certain number by the same power of 10. the product she gets is 40,000 and the quotient she gets is 0.000004. find yara’s number and the power of 10 she used. explain your reasoning

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.  

x = 12

y = 1

for the points!
