Several students were planning a bike tour. they estimated the following expenses andi incomes

1.) write an expression for the total expenses n for n bikers.

2.) write an equation for the total income l for n bikers

3.) write an equation for the profit p for n bikers

4.) find the profit for 25 bikers.

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.
