Jada makes sparkling juice by mixing 2 cups of sparkling water with every 4 cups of apple juice. How much sparkling water does Jada need if she uses 16 cups of apple juice?

8 cups of sparkling water

Step-by-step explanation:

This is a ratio problem, the ratio is 2:4 because there are 4 cups of apple juice for every 2 cups of sparkling water, if there are 16 cups of apple juice, there will have to be 8 cups of sparkling water because if you do something to one part of the ratio, you have to do it to the other part too. you have to multiply 4 x 4 to get 16, so if you multiply 2 and 8, you get 16, which then makes the ratio equivalant and correct

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.
