What is 8.7 x 10-6 in standard notation? A. 1/8.79 (fraction)
B. 8,700,000
C. 0.0000087
D. 0.000087

C.

Step-by-step explanation:

If the exponent n the 10 is negative you move the decimal to the left. If it is positive you move it to the right.

So 8.7 * 10^-6 you would move the decimal to the left 6 places

.0000087

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.
