if de = 3x, ef = 2x, and df = 10, what is de?



Step-by-step explanation:

As we know that

DF=DE+EF

by putting values

10=3x+2x

10=5x

10/5=x

2=x

now as

DE=3x

by substituting value of x

DE=3(2)

DE=6

b.my answer is b.

brainliest

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.
