Under her cell phone plan, Sofia pays a flat cost of $54.50 per month and $4 per gigabyte. She wants to keep her bill at $73.70 per month. Which equation or tape diagram could be used to represent the context if g represents the number of gigabytes of data Sofia can use while staying within her budget? A 54.5g 4 54.5 54-5 54.5 73.7 B. 73.7 = 54.59 +4 С 4(9 + 54.5) = 73.7 D 54.5 4. 4 4 73.2​

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

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.
