What is the slope of a line that is perpendicular to the line shown?

-3/2

Step-by-step explanation:

First find the slope of the line

m = (y2-y1)/(x2-x1)

   = (3--1)/(3 - -3)

   (3+1)/(3+3)

   4/6

  2/3

We want a line that is perpendicular, which is the negative reciprocal

-1 /(2/3)

-3/2

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.
