A rock is thrown off a 30 m cliff at a 45° angle above the horizontal. Which is the following is true regarding the
acceleration of the rock?
(A) The acceleration will be of magnitude g and have
both horizontal and vertical components.
(B) At the peak of the rock’s path, the magnitude of
acceleration will be half of what it was when the
rock was initially thrown.
(C) The acceleration will be of magnitude g and in a
downward direction.
(D) The acceleration will be downward during the
rock’s ascent and upward during the rock’s
descent.
(E) The acceleration will increase throughout the
rock’s flight.

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.
