HELP! i know it looks easy but im not getting it. Select 2 strategies that we can use to subtract 563-192. Choose 2 answers: (Choice A) Add 100+90+210 (Choice B) Evaluate (563-200)+8 (Choice C) Subtract 571-200.

Choice B & C

Step-by-step explanation:

563 - 192 = 371

The subtraction equals to 371.

100 + 90 + 210 = 400

The answer does not equal to 371 in choice A.

563 - 200 + 8 =  371

The answer equals to 371 in choice B.

571 - 200 = 371.

The answer equals to 371 in choice C.

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.  

answer: (-6,3)
