of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane that only allows certain molecules to diffuse though (Lab Manual 7e‚ 2010). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions

Objective To determine soluble solid concentration in some fruits including tropical and temperate fruits by using handheld refractometer. Introduction “Sugar are the major soluble in fruits juices and estimate of sweetness. Other soluble materials include organic and amino acids‚ soluble pectins‚ and others. Soluble solid concentration can be determined in a small sample of fruits juice using a hand held refractometer. The measurement must be made at 20°C to get an accurate value. This instrument

reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with ink inside it‚ when you write‚ ink comes out‚ right? You can draw‚ you can write‚ then when you finish and get your pen off of the paper‚ the ink stops coming out. Enzymes are like that‚ they

completely unaware of the horrific events about to unfold that would overshadow their city still today. The citizens of Dachau were oblivious that their city was going to become the origin of concentration camps and of the Holocaust‚ the mass murder committed by the Nazi s in World War II. Dachau Concentration Camp‚ which would soon be placed on the edge of their community‚ would serve as a model for all Nazi extermination camps. This perfect prototype of a Nazi killing machine has come to represent

the amount of meat tenderizer give different results? The amount of meat tenderizer did give different results‚ cup â»2 with the least amount of tenderizer did not break down as much as the cup â»3 with the most tenderizer. Conclusion According to this lab it demonstrated that Jell-O does have protein since the enzymes in the meat tenderizer were able to break down the Jell-O and prevent it from setting. This data also shows that the amount of enzymes effects the breakdown of proteins since
