Mrs. Watanabe is choosing a cell phone plan. One plan costs $35 a month and includes 450 minutes. The charge for each minute over 450 is $0.16. The company also offers an unlimited calling plan with a $55 monthly charge.

this is only a statement with no question so I'm just assuming the question here:

It would be cheaper to buy the $$35/month plan if he uses under 575 min/month and cheaper to buy the $55 plan if using over 575 min/month

Step-by-step explanation:

$35 + x$0.16 = $55

-35. -35

x$0.16 = $20

÷ 0.16. ÷0.16

x = 125 min

450 + 125 = 575 min

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.
