in neutral pH. To do this the experiment was carried out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After concluding the reactions they were placed into a spectrophotometer (A580) for analysis. Graphing the values of the absorbance to time for each pH it was found

Aim: Investigate the effect of different temperatures and chemicals including various pH levels‚ alcohol and detergent on the cell membrane structure as well as function. Hypothesis: Increasing the temperature and pH levels which the beetroot membrane cells are exposed to will increase the amount of dye that passes out of the membrane. Materials: Part A • Bunsen Burner‚ Tripod and a Wire Gauze • 250mL Beaker • A 100° thermometer • Matches • 10mL measuring cylinder • Sticky labels and a Pen

Effects of the Bottleneck and the Founders effect Cecil Smith GS102 Grantham University Online The bottleneck effect happens when something of a great devastation has happened‚ causing a great amount of people to lose their lives and leave behind very few people at the most. The bottleneck effect happens at random and can kill of a whole population and with it can also wipe out the gene pool by doing so. An example of the bottleneck effect would be something like a tsunami‚ or an earthquake‚ which

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the absorbency will decrease. The absorbency

pH Levels and Temperature Water is very important in life. Without water‚ nothing could survive. Water needs to be clean to drink. People all over the world are using filters to clean and purify water. The best type of filter‚ out of dirt‚ cloth‚ and grass‚ is the grass filter (Allen). The grass filter is completely natural‚ therefore it cleans and purifies the water the best. Does a grass filter affect the pH level and temperature of lake and stream water? The temperature of water affects how solubility
