Savion listed the steps involved when nuclear power plants generate electricity. nuclear reaction occurs. nuclear energy is converted to radiant and thermal energy. heat is used to generate steam. light and heat are released. steam turns turbines. mechanical energy is converted to electrical energy. which best explains how to correct savion’s error?
a. in step 2, change “radiant and thermal ” to “chemical and mechanical.”
b. reorder the steps so that step 4 appears before step 3.
c. reorder the steps so that step 6 appears before step 5.
d. in step 6, change “mechanical” to “thermal.”

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
