Solve the following 19+n=30

n=11

Step-by-step explanation:

In order to solve this equation, we need to find out what n is. We have to get n by itself on one side of the equation. Perform the inverse operations to both sides of the equation.

19+n=30

19 is being added to n. The inverse of addition is subtraction. Subtract 19 from both sides.

19-19+n=30-19

n=30-19

n=11

Let's check out solution. Plug 11 in for n in the original equation.

19+n=30

19+11=30

30=30

The statement above is true, so we know our solution is correct.

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.
