Step-by-step explanation:

1) S = 450 + 70 W

2) 450 + 70 x 12 = 1290

Equation:

$450+70W=S

Total amount of money after 12 weeks: $1290

the answer is 489

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.
