A bank exchanges United States currency for British courrency at the rate of 1.60 dollars to the £ . (a) Calculate, in dollars, the amount received for £ 150.
(b) Calculate, in £ ,the amount paid $ 500 by a customer.

Remember that £ has a greater value compared to $ and vice versa.

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.
