Write the trigonometry expression as an algebraic expression in u and v. Assume that the variables u and v represent positive real numbers.

answer: add the !

step-by-step explanation: then we will answer

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.  

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
