68 miles to 42.5 miles increase decrease question 2 find the percent of change.

The distance from 68 miles to 42.5 miles decrease .

The Percentage of change is 37.5% .

Step-by-step explanation:

Formula

Where

Change in value = |Final value - Initial value|

As given

68 miles to 42.5 miles .

Thus the distance decrease .

Final value = 42.5 miles

Initial value = 68

Change in value = |42.5 - 68|

Change in value = |-25.5|

Change in value = 25.5

Putting all values in the formula

Percentage change = 37.5 %

Therefore the Percentage of change is 37.5% .

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.
