beads we put in the tube and placed all the beads on a paper towel. This beads removed were arranged for the experiment 3 For the fourth experiment which is the respirometer four, we put 25 ml of water in the 50ml of the graduated tube and from there we proceeded to drop 25 germinating corn seeds. To be able to determine the volume of water that has been sent off, which we discovered that the volume of the water dispatched is equal to the volume of corn. After this we proceeded to recording the volume of the germinating corn after taking the volume of the corn we removed the corn seeds and then further placed it on a paper towel. The volume of the germinating corn that we recorded was 10. For the experiment 5 which is respirometer 5, we refilled the graduated tube to 25 ml by adding water to the tube, then after that we drop 25 dry non germinating corn in the tube.…show more content… After this was done, we then proceeded to remove the non-germinating (dormant) corn seeds and the beads from the tube and we placed them on a paper towel. For experiment 6 which is the respirometer 6 we refilled the graduated tube to 25 ml with water and added enough bead to make sure that it equals the volume of the germinating corn after this experiment was performed we removed the beads and placed them ,on a paper towel after this experiment was concluded we then proceeded to prepare the respirometer. first of all we placed the absorbent cotton balls at the bottom of each of the respirometer vial this was after we made sure that that the respirometer was dry after this we used a dropping pipette to thoroughly soak the cotton with 2 ml of 15% of KOH solution . one of the precautions we avoided in this experiment was to make sure that we avoid skin contact with the KOH and also not get KOH by the edges or sides of
