Mutations are changes in the genes of living things. Mutations are common in all life forms and usually harmless. In fact, sometimes they help organisms survive. However, people often think that the word mutation means something dangerous. Which best describes the question "Why do most people think mutations are dangerous?" a scientific question, because it asks about mutations that happen in nature a scientific question, because it asks about most people instead of just a few not a scientific question, because it asks about what people think instead of how nature works not a scientific question, because it asks about how mutations can be helpful to life in nature (ANSWER IT FIRST AND GET BRAINLIST)

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
