Ms. Rios mowed 2

of her lawn. Her son mowed

of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?

Ms Rios mowed more

Step-by-step explanation:

I'm assuming that there's 100% of the lawn so if Ms Rios mowed 27% of the lawn when it was at 100% it would be at 73%

Now if her son mowed 14% and it was still at 100% it would be at 86%

So in the end Ms Rios mowed more of her lawn

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.
