i need to find out what the following chemicals do to human serum (deprotineated) 8-hydrooxyquinoline and 2-amino-1-methylpropanol in regards to calcium salts or pH

there are four basic types: mustle neron connective undiffrentiated they (in the human body) can be divided into about 220 types animal cells provide a simular functions to our own. The further away the genus, or kingodom the more diffrent the cell. Eg. we have very simular red cells to monkeys but bird red cells are compleatly diffrent as they are nucliated. i hope this answers your questions

Ok got a problem. There is a 140mmol/L stock standard of Na and the working standard made from this is 70mmol/L. If i follow the instructions i get 6.4mmol/L of Na. Instructions: Mix: 0.50mL Li standard 0.025mL Na stock standard (140mmol/L) 4.475mL water If i mix these my calc. shows it'll be 6.4mmol/l calculations: 140mmol/L / 1000 = 0.14mmol/mL <-L to mL 0.14mmol/mL * 0.025mL = 0.0035mmol/0.025mL <- how many moles are in 0.025mL 0.0035mmol/5mL <-becasue there is five mL total in the mix 0.035mmol/5mL * 200 = 6.4mmol/L <-converting 5mL into 1L please can someone help me find out what im doing wrong? please post with the working out.
