What is the answer Gregory can buy 4 pounds of wheat flour for $8 and 5 pounds of rye flour for $20. he has $12 to spend on a flour mixture. what is the linear equation

(4*8)+(5*20)-12

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.
