2. a rectangular field measures 10ft by 3.5ft. what is the area of this field?

The area of this rectangular field is 35 square feet

Step-by-step explanation:

Length of the rectangular field = 10 feet

Width of the rectangular field = 3.5 feet

Area of the rectangular field = Length * Width

Area of the rectangular field = 10 * 3.5

Area of the rectangular field = 35 square feet

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.
