A farmer has 300 ft of fencing and wants to build a rectangular pen for his goats. To maximize his resources, he uses the side of his barn as one of the sides of the pen. What is the maximum area that he can enclose

I need more info on the size of the barn to answer.

Step-by-step explanation:

47

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.
