    Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate

    Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

    • 4 Pages

    This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

    Polypeptides‚ better known as proteins‚ carry out nearly all of a cell’s functions. A protein is made up of at least one or more amino acid polymers. The necessity of proteins for life is unequivocal‚ not only do they help to form the structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell

    ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

    go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal conditions where there are no outside disturbances. There were weight differences in the potatoes which could have caused thicker potatoes to absorb more than others. It was a little impossible to obtain the same
