kiran bought two school bag for rs1000.while selling at the same rate, he found that there was a profit of 20% in one and a loss of 10% in another. Find the cost price of each bag.

answer:      

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.
