26

Step-by-step explanation:

26 units

Step-by-step explanation:

To find the distance on a number line, take the absolute value of any negative numbers and add.

|-13| + 13

13 + 13

26

Best of Luck!

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.
