The ratio of boys to girls in Ms. Ballou’s class is 3 to 4. If there are 28 total students in the class, how many more girls are in the class than boys?

12 girls than boys

Step-by-step explanation:

3+4=7

3/7 x 28 = 12

So add 3+4 and then put 3 the first number and then answer into a fraction 3/7 and multiply with how many students their and that's it

9 x 8 divided by (5-3)=36

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.
