Decide, without calculation, if each of the integrals below are positive, negative, or zero. Let D be the region inside the unit circle centered at the origin. Let T, B, R, and L denote the regions enclosed by the top half, the bottom half, the right half, and the left half of unit circle, respectively.

1. ∬B xe^xdA

2. ∬R xe^xdA

3. ∬T xe^xdA

4. ∬D xe^xdA

5. ∬L xe^xdA

? Positive Negative Zero

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

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.  

i use my brain for prombles like this maybe you could try it
