For a 7-day bike trip, a cycling group can bring no more than 150 pounds of gear, food, and water. The weight of the food is 2/10 the weight of the water. The weight of the gear is 3/10 the weight of the water. Which inequality describes x, the number of pounds of water the group can bring?

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.
