The cost of a machine is supposed to depreciate each year by 12% of its value at
the beginning of the year. If the machine is
valued at 344,000 at the beginning of 2008,
find its value
(i) at the end of 2009.
(ii) at the beginning of 2007.​

step-by-step explanation:

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.
