Calafornia, at an elevation of -86 meters. you hike at a point of elevation at 45 meters. what is the change in your elevation?

The change in elevation would be 131 meters.

i did it myself and i got 4.2 (b) hope its right

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.
