test‚ the objective was to find the test materials that have a reducing sugar. In the reducing sugar test benedicts was used. In the grease spot test‚ the objective was to find all the samples that had a lipid. Another one of the lipid tests were the dye test which was a more specific test to find the substances that all contained a fat by using a solution of Sudan 4 and water. The protein test’s purpose was to determine all the test materials that contained a protein by using biuret solution. The procedure

Punk culture has to deal with clothing‚ jewelry‚cosmetics and hairstyles as the whole part of punk culture.

The 80’s punk hairstyle included colored hair‚ spikes‚ infamous mohawk and other unconventional

MICROSCOPE In this experiment‚ we have learned several basic molecular biology techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained it is called positive staining. It

Osmosis is the movement of water across a membrane. It always navigates to the area of the membrane with a higher solute concentration. We take a closer look at the effects of osmosis in this lab through the examination of red blood cells (sheep)‚ plant cells (elodea)‚ and active transport in yeast. Under the microscope‚ we can determine the effects on plant and animal cells exposed to hypotonic‚ hypertonic‚ and isotonic sodium chloride solutions. Plant cells have a cell wall; however‚ animal cells

The dye particles also diffused against a high to low concentration gradient through the visking tubing which is not osmosis as it is the movement of particles rather than as the molecules were able to move through the semipermeable membrane whereas the sucrose solution particles are too large to diffuse through the semipermeable membrane of the visking tubing so they remain within the tubing. This causes the dye to move from within the tubing and out to the water and stain it with the dye colour
