Table 1: Oxygen use of goods and services in pea seeds at agency temperature. to each one test vacuum piping contained 20 pea seeds which were pretreated for 15 transactions in 0.2M saccharose solution at 30OC and 100OC. Each test underpass contained a cotton orb dampened with 15% KOH, accordingly a roll of glass wool, then 20 pea seeds soaked at the certain temperature, then other ball of glass wool, and then a nonher cotton ball dampened with 15% KOH. The top was cover with a rubber chaw which had a 1 ml pipette and a syringe. accordingly both test tubes were move in a room temperature bath. Then 3-4 drops of iodine were added and adjusted. aft(prenominal) 5 minutes, the position of the tint was recorded and then afterwards every 2 minutes for 20 minutes the dyestuff position was recorded.

Figure 1: Each test tube contained 20 pea seeds which were pretreated for 15 minutes in 0.2M sucrose solution at 30OC and 100OC. Each test tube contained a cotton ball dampened with 15% KOH, then a ball of glass wool, then 20 pea seeds soaked at the certain temperature, then another ball of glass wool, and then another cotton ball dampened with 15% KOH.



The top was covered with a rubber stopper which had a 1 ml pipette and a syringe. Then both test tubes were placed in a room temperature bath. Then 3-4 drops of iodine were added and adjusted. After 5 minutes, the position of the dye was recorded and then after every 2 minutes for 20 minutes the dye position was recorded. This shows test tube # 1 increased very slightly by somewhat 0.0-0.1 every 2 minutes. Test tube #2 did not increase at all.











Table 2: Oxygen consumption in pea seeds at 40OC. Each test tube contained 20 pea seeds which were pretreated for 15 minutes in 0.2M sucrose solution at 30OC and 100OC. Each test tube contained a...If you sine qua non to get a full essay, order it on our website: Orderessay
