Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. gh
-10
2. g2 - h
10
3. g + h2
-21
4. g + h
-4
5. h - g
2
6. g - h
46

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.  

current in the circuit at time t is /, then the power delivered to the resistor is
