A bell shaped curve on a probability distribution always indicates a normal distribution but the shape of the bell curve can be tall and narrow or wide and flat. The shape tells about the data. Which of the following shows the data closest to the mean..

answear:

a

step-by-step explanation: a

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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.
