Nick needs 1.3 pounds of swiss cheese for a recipe. he can choose from the 2 chucks of cheese shown. round the weight of each chunk of cheese to the nearest tenth. which chunk of cheese rounds to 1.3? explain your answer.

step-by-step explanation:

b and c

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.
