Grace wants to earn $400 for her class trip. She started her own landscaping business. She charges $6 an hour for mowing the lawns for 23 hours and she pulled weeds for 9 hours. If she pulled weeds for 8 hours in May, for how many hours does she need to mow the lawns to meet her goal?

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.
