What is a correct way to evaluate the expression 80 - (50 – 35)?

Step-by-step explanation:

According to PEMDAS, you need to deal with parenthesis first

50-35 = 15

Now you need to multiply, or distribute the negative sign

-(15) becomes -15

Finally, you need to subtract 15 from 80

80-15 = 65

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.
