The ratio of boys to girls on rowans swim team is 2:3.if there are 40 total swimmers on the team, how many of them are girls?

The ratio of girls is 24.

Step-by-step explanation:

If the total amount of swimmers is 40, you can divide it by 8 to get 5 multiples.   If three of those 5's belong to the ratio of girls, the equation is 3 x 8. The answer is 24.

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.
