A line passes through the points (4,21) and (9,26). Write a linear function rule in terms of x and y for this line

step-by-step explanation: noo

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

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.
