The height of a cone is decreasing at a constant rate of 9 feet per second. The volume remains a constant 689 cubic feet. At the instant when the height of the cone is 88 feet, what is the rate of change of the radius? The volume of a cone can be found with the equation V=\frac{1}{3}\pi r^2 h. V= 31​ πr 2 h. Round your answer to three decimal places.

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.
