The statemcnt of the problem cstablishcd was how much is thc increase of biomass hetwccn each evolut.ionary cycle "corn" (Zea mays Linn.), in two climatic conditions of Lamas?. Between the variables and independent variables, the evolutionary cycle of the corn, the dcpendcnt variable, the amount of accumulated biomass. Thc hyp...
