Marko is buying carpet for his bedroom floor. his room measures 13 feet by 12 feet. how many square feet of carpet will marko need to cover the floor in his room? 25 square feet 50 square feet 156 square feet 312 square feet

The floor area is 12 ft by 13 ft: A = (12*13) ft^2 = 156 ft^2

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.
