TheEffectofCaffeineontheHeartRatesofThreeDayOldChickEmbryos
Objective The purpose of this experiment is to observe the effect of caffeine on the heart rate of three day old chick embryos by directly treating them with five different concentrations of caffeine.Introduction The first functional organ of chick embryos is the heart (Gilbert, 2003). At three days, chick embryos already have a tubular heart struc......阅读全文
