PLEASE HELP PLEASE Vertical Motion Model: h= -16t2+vt+s
h= final height of object
t= time
v= initial velocity
s= initial height

answer:

c. the third graph

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.  

1. minimum

2. 6400

3. eight

hope this !
