starch. During the experiment we observed that bacterial amylase had faster enzymatic activity than fungal amylase; bacterial amylase achieved 100% hydrolysis at 40°c and 60°c at 2 minutes time and fungal amylase achieved partial hydrolysis at 60°c at 4 minutes time. With all of this we can say that the optimal temperature for fungal and bacterial are almost the same‚ but bacterial have faster amylase activity than fungal and that is possible because bacterial amylase is found in human saliva‚ were

Biology Lab Scientific Paper Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms during pregnancy and how the baby’s body functions as it grows in the womb and after birth. Usually‚ a baby is born with 46 chromosomes but babies with Down syndrome have an extra copy of one of these chromosomes‚ chromosome 21. A medical term for having an extra copy of a chromosome is trisomy. Down syndrome

The first slinky’s mass was weighed‚ using a scale‚ and its tension was measured using a force measurer 2. The slinky was stretched to 4m. 3. The linear mass density was solved for‚ by dividing the mass by the length. 4. The theoretical velocity was solved for‚ using the equation

AP Chemistry Kinetics Lab Abstract: The purpose of this lab is to learn how to write law expressions‚ determine orders by graphs‚ and calculate rate constants. By determining the number of drops of sodium hypochlorite necessary to make a diluted food dye change to colorless in less than three minutes helps calculate the absorbance which can then be analyzed to find the pseudo rate constant and eventually leading to the rate constant and the rate law. The results show that the m and n are both 1st

Transferred 25 ml of the substrate B into the cuvette using the pipette. 4. Referring to the timer to determine when 1 minute has passed transferred 5 ml of enzyme B into the cuvette and quickly into the sample holder of the spectrophotometer. 5. Recorded the absorption value at the 1 minute mark 6. Started a new experiment by removing the cuvette from the

The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +
