What is 4×5+9(3)÷108÷1

20.25

Step-by-step explanation:

4 * 5 + 9 * (3) / 108 / 1

Let's break down the equation:

4 * 5 + 9 * 3 / 108

Now we use Order of Operations a.k.a. PEMDAS to solve the equation:

20 + 27/108 = 20 + 1/4

20 + 1/4 = 20.25

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.
