Which best describes the speed and velocity of the graph?

a)
both speed and velocity are changing.

b)
the speed and velocity remain constant.

c)
the speed is constant and velocity is changing.

d)
the velocity cannot be determined from the graph.

A - Both speed and velocity are changing.

Though the answer is option A but option D can also be true. The velocity cannot be completely determined from the graph.  This is because, velocity is based on the direction and motion and the graph is not completely justifying this.

Though velocity cannot be determined, but it is clear from the graph that velocity is changing, because the speed is changing.

Therefore, option A is completely true.

the y will be in still but your answer will be y x 3

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.
