Pls Help me I'm so confused. All I know is that this question is about the System of Equations Alex spent $14 on a movie ticket and a large box of popcorn. Popcorn costs $4 less than a movie ticket. How much did the large box of popcorn cost?

A. $4

B. $5

C. $6

D. $7

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.
