the oxygen saturation of a lake is found by dividing the amount of dissolved oxygen the lake water
currently has per liter by the dissolved oxygen capacity per liter of the water, and then converting that
number into a percent. if the lake currently has 6.4 milligrams of dissolved oxygen per liter of water and
the dissolved oxygen capacity is 9.5 milligrams per liter, what is the oxygen saturation level of the lake,
to the nearest percent?
a. 64%
b. 67%
c. 70%
d. 89%
e. 95%

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.  

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
