For your research project, your group is planning to treat embryos with acetaminophen at a concentration of 25ug/L plus varying concentrations of dextromethorphan between 0 and 100 uNY. You have stock solutions of 500ug/L acetaminophen and 1mM dextromethorphan to work with. If you wanted to treat some embryos with final concentrations of 50ug/L acetaminophen and 10uM dextromethorphan in a total volume of 10ml, how would you make up 9ml of solution containing both acetaminophen and dextromethorphan, to which you could add 1ml of embryo water containing the embryos? Add 0.2ml of 500ug/l acetaminophen and 0.5ml of 1mM dextromethorphan to 8.3ml of water. Add 0.1ml of 500ug/l acetaminophen and 0.5ml of 1mM dextromethorphan to 8.4ml of water. Add 0.5ml of 500ug/l acetaminophen and 0.1ml of 1mM dextromethorphan to 9.4ml of water. Add 0.5ml of 500ug/l acetaminophen and 0.1ml of 1mM dextromethorphan to 8.4ml of water. Add 0.5ml of 500ug/l acetaminophen and 1ml of 1mM dextromethorphan to 7.5ml of water
