What amount of amylase is the best to produce a better reaction with starch? A 1% solution of amylase‚ made from 0.15g of amylase added to 15ml of water‚ a 2% solution of amylase made of 0.3g of amylase added to 15ml of water‚ and a 0.5% solution of amylase made of 0.75g of amylase to 15ml of water were created. A 0.25% starch solution was also created‚ and 3ml was added to each of the 4 test tubes. 1 drop of iodine was added to each test tube. 4ml of the 1% solution was added to the first test

effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water. We measured

Buffers‚ and pH‚ and Diffusion oh my The pH of a solution is the measure of the concentration of charged Hydrogen ions in that given solution. A solution with a pH lower than seven is considered to be acidic. A solution with a higher pH is a base. It is very important for organisms to maintain a stable pH. Biological molecules such as proteins function only at a certain pH level and any changes in pH can result in them not functioning properly. To maintain these constant pH levels‚ buffer solutions

Title: pH and buffer solutions Aim This experiment was carried out to determine the role of buffer solution and the factor which affect the buffer capacity. Besides‚ this experiment was carried out to investigate the solubility of protein casein over a range of pH concentration. This experiment also was carried out to determine the isoelectric point of the casein and the effect of the isoelectric point toward the casein solution.

The Effects of pH on Slime Mold Dg Nicole Harris BIOL181 – 059 1 December 2011 The theory that slime mold is attracted to acidic solutions was examined by the slime mold‚ Dg. Dg’s preference of pH was examined by using a variety of pH solutions in a petri dish. The data suggests that the growth of fruiting bodies observed in pH 9 was comparable to that of pH 4.
