Please answer.

A.)

 1.) b = h(2)

 2.) p = b - 3

B.) 10

C.) 5

Step-by-step explanation:

A.)

 1.) The birch tree is twice the size of the orange tree so, birch = orange * 2

 2.)  The peach tree is 3m shorter than the birch so, peach = birch - 3meters

B.) b = 5(2)

C.) 8 = 4(2)

     p = 8 - 3

you probably already have the answer but anyways it's b. 15.0

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.
