A shark's depth in meters relative to sea level over time in minutes, x, is modeled as a parabola. At time 1 minute the shark is swimming upwards and is at a depth of 7 meters. The shark continues to swim toward the surface for another minute and then turns and begins to swim downwards and returns to a depth of 7 meters at time 3 minutes. What is the axis of symmetry of the graph of the parabola?

answer is

c) 4

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.
