EXTRA CREDIT: Briggs is downloading movies and songs. Each movie costs $5 and each song costs $1. Briggs' mom said he can have at most 10 downloads and he can spend at most $15. Write a system of linear inequalities. Let x represent the number of movies Briggs can download and y represent the number of songs he can download. Graph the inequalities. Do not scale your graph

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.
