what did baby boomers do to the population age - increased the population diversity age to a higher age what is the dependency ratio - the number of people who are too young or too old to work, compared to the number of people in their productive years what is dissociative disorder vs retrog...

Thin layer chromatography can use silica plates which are very polar. Will polar or non polar substances have lower Rf values on this plate? ANS -Polar substances - they will have a higher affinity for the silica and thus will not travel as far as the non polar substances A titration of a stro...
