Part A: The table shows the number of students going on a field trip. One chaperone is needed for 12 students. (5th grade: 310 students, 6th grade: 305 students, 7th grade: 225 students) Write two equations with variables that you can use to find the number of chaperones needed.

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.
