enzyme peptidyl transferase. This inhibition results to the prevention of the transfer of amino acid for growing peptide chains which leads to the inhibition of the formation of bacterial protein. (Michigan State University‚ 2011). Chloramphenicol is a broad-spectrum antibiotic. (Hitner et al.‚ 2016). Bacterial microorganisms become resistant by the inactivation of chloramphenicol through the enzyme acetyltransferases. (Rang et al.‚ 2016). Chloramphenicol resistance are very common in Staphylococcus

Concentration Camps in Vienna The Auschwitz concentration camp complex was the largest of its kind established by the Nazi regime. It included three main camps‚ all of which deployed incarcerated prisoners at forced labor. One of them also functioned for an extended period as a killing center. The camps were located approximately 37 miles west of Krakow‚ near the prewar German-Polish border in Upper Silesia‚ an area that Nazi Germany annexed in 1939 after invading and conquering Poland. The SS authorities

Experiment 2: Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins

The Power of Concentration By Remez Sasson When I was a child‚ I saw how a magnifying glass could burn a piece of paper‚ when the rays of the sun were focused through it. The fire could start only when the sun’s rays were concentrated to a small point. When the magnifying glass was moved too far away or too close to the paper‚ the rays were not focused enough and nothing happened. This experience describes vividly the power of concentration. This power can be described as focused attention. It

Of course‚ at times‚ people may guide them as to how to gain concentration‚ but the key to having full concentration is in our hands.

An investigation to see how much oxygen is given off when different concentrations of catalase are added with hydrogen peroxide. Aim: To see if changing the concentration of catalase (found in celery) with hydrogen peroxide affects the amount of oxygen given of. Background Information: (Hydrogen peroxide - H2O2 1/2O2+H2O) Enzymes: Hundreds of chemical reactions happen simultaneously inside living cells and it’s the job of enzymes to control and regulate the various metabolic

CHAPTER 1 INTRODUCTION A. Background of the Study Concentration has been defined as the ability to direct one’s thinking in whatever direction one would intend. Concentration plays vital roles in doing well in studies. A student has to work really hard and concentrate firmly to get concepts well in mind. All students have the ability to concentrate some of the time. But at other times students’ thoughts are scattered‚ and their minds race from one thing to another. They don’t have the ability to

CONCENTRATION AND DILUTION Physiology 1‚ Las Positas College Name: In science‚ concentration is a measure of the number of particles (solutes) in a given volume. If one room has 100 people in it‚ and a room of equal size has 50 people‚ one can say that the concentration of people in one room is twice that of the other. Quite simple‚ isn’t it? On a molecular level‚ consider whether you put one lump or two of sugar‚ or no sugar at all‚ in your coffee. If you use two lumps‚ you prefer twice
