Experiment 1 : Design and preparation of buffers effective at different pHs Abstract The body uses natural buffers to maintain the many different pH environments in our body. This is important for optimum activity of our enzymes. When doing experiments in vitro using these enzymes it is important to mimic intracellular conditions using artificial buffer systems in order to obtain accurate results. In this experiment the buffering properties of three artificial buffer systems containing acetic acid‚ Gylcine

t Design and preparation of buffers effective at different pHs Abstract These experiments aimed to determine the optimum pH ranges various buffers are effective and provide opportunity for the use of the Henderson-Hasselbalch equation to prepare a buffer of a specific pH. Three different buffer systems were initially investigated; volumes of weak acid and weak bases of specified concentration were prepared and titrated against strong acid or strong base solutions with pH readings taken at frequent

Title: Mitosis and Meiosis Abstract: There are two types of nuclear division‚ mitosis and meiosis. Mitosis is usually used for the growth and replacement of somotaic cells‚ while meiosis produces the gametes or spores used in an organism’s reproduction. Hypothesis: Mitosis occurs in whitefish blastula and onion root tip‚ and it is easily observable. Meiosis and crossing over occurs in the production of gametes and spores. Materials: This lab required prepared slides of whitefish blastula

algorithms must be used in conjunction with source flow control algorithms to control congestion effectively in noncooperative environments. While designing algorithm they consider mainly three things 1) bandwidth‚ 2) promptness‚ and 3) buffer space. They conduct tests using six different scenarios comparing FQ against FCFS using generic‚ Jacobson and Karels (JK)‚ and DECbit flow control algorithms. Test results show that FQ provides reasonably satisfactory congestion control for given
