Lunch Lines Paul, Jane, Justin, Sarah, and Opal were finished with lunch and began playing with drink straws.
Each one was making a line design using either 3 or 4 straws. They had just come from math
class where they had been studying special angles. Paul pulled his pencil out of his book bag
and labeled some of the angles and lines. He then challenged himself and the others to find
all the labeled angle measurements and to determine whether the lines that appear
to be
parallel really could be parallel.
Choose ONE of these and fill in all the missing angles.

which expression represents the approximate length of bc?

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.
