They also stabilize the plant. The root is made up multiple parts starting at the bottom with the root cap‚ then the zone of cell division next is the zone of cell elongation‚ and at the top of the root is the zone of differentiation. To figure out what section of the root has the highest number of cells in mitosis we

INTRODUCTION For this experiment we studied an oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon‚ cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results)‚ and then weighed it (individual
