What is 4 = 4( c-18)​

c = 19

Step-by-step explanation:

Let's rephrase this equation:

4(c-18) = 4

Let's plug in 19

4(19-18) = 4

19-18 = 1

4 multiplied by 1 is 4 so therefore, c = 19

hope this !

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.
