Raj and Aditi like to play chess against each other. Aditi has won 12 of the 20 games so far. They decide to play more games. How many more games will Aditi have to win to have a 70% winning record? 12 + x = 0.70(20 + x) x = x equals StartFraction 20 Over 3 EndFraction is approximately 6.67. ≈ 6.67 She will have to win 7 more games to have a 70% winning record. How many more games will Aditi have to win to have an 80% winning record? The linear equation that models this is . Aditi would have to win more games to have an 80% winning record.

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.
