What is the function of the mordant iodine in a Gram staining procedure? A mordant causes the crystal violet to run. A mordant fixes the bacteria to the slide. A mordant keeps dye attached to an object. All of the above 5. What is the order of reagents used in the Gram stain? crystal

Cockroaches and Hemolymph Concentration in the Body Abstract This lab was conducted to determine the concentration of hemolymph in the body of a cockroach. It was done by making serial dilutions to make a standard graph by injecting a dye into a cockroach and determining the concentration at different times with the use of a spectrophotometer to find the optical density which is measured in absorbance. Results showed that the concentration was not within the pre-experiment research range

Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography‚ a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action‚ the. components

Coconut Water Wax A Breakthrough in Fruit Preservation ABSTRACT This study utilized coconut water to produce a wax preservative for fruit and other foodstuff. Different fresh fruits were collected and assigned to four different treatments: * Treatment I (Control): fresh fruits without anything done * Treatment 2: fruits soaked in coconut water for 10 minutes * Treatment 3: fruits covered with coconut water wax * Treatment 4: refrigerated fruits The fruits used were oranges

known dye samples and three unknown dye mixtures will be subjected to agarose gel electrophoresis. Some of the dyes will be attracted to the negative electrode and some to the positive electrode depending on their overall charge. Each of the known dyes will exhibit a unique gel migration distance that relates to its molecular size and net charge. You will identify the components of the unknown dye mixtures by comparing the migration distances and direction of migration of the unknown dyes to those

coloring for different periods of time‚ then the mass of the egg will differ‚ and the red food coloring will make the egg overall bigger than the blue.” However‚ the data proved that the color of the dye does not affect the osmotic properties of a naked egg in food dye. Both the red and blue food dye at the end of the experiment ended around 100 grams (blue at 99.86‚ and red at 100.84). By just this‚ you would tell you that red food coloring caused more of a gain in mass. However‚ you can tell on
