solution procedure for transportation problems

1. Prepare acidic solution of ammonium molybdate by dissolving 1 g of it in 10-15 ml of nitric acid. 2. Take 1-2 drops of this solution on a glass slide and mount the section of chlorophyll-free leaf in it. Observe under the microscope after 30 minute..

Take 25g of fresh spinach leaves in a pestle and morter. Crush them with 10 ml of 80% acetone. Add a pinch of calcium carbonate and crush again. Filter the extract on a Buchner funnel. The drop green coloured filtrate containing chlorophylls is obtained. Pour the filtrate in a test tube. Place the..

In this procedure, a drop of the test solution is applied as a small spot near one edge of the filter paper and the spot is dried. Then, the end of the paper strip is dipped into a developing solvent. The liquid is sucked up through the capillaries of the paper; it reaches the ..

The antibody, which is specific to the antigen to be detected must be present in the kit. The sample, which is suspected to contain the antigen is immobilised on the ELISA plate. The specific anti body is added and allowed to react with the antigen. Washing will remove all free antibodies. The ant..

1. Mount a section of the chlorophyll-free leaf in water. 2. Place a cover slip over it. 3. Pour a drop or two of 50% H 2 SO 4 on one side and drain off water from the other side by means of a blotting pap..

Small pieces of coal are taken in test tube A. Test tube A is fitted with a rubber stopper carrying a delivery tube and is clamped to the clamp stand. Test tube B containing water is clamped vertically to the clamp stand. The apparatus is assembled as shown in the figure. The burner i..

A mixture of sodium acetate and soda lime is taken in a hard glass test tube fitted with a rubber stopper carrying a delivery tube. The test tube is clamped to a clamp stand. The apparatus is arranged as shown in the figure. The test tube is heated strongly. Sodium acetate reacts with..

The unknown acid is dissolved in water and treated with a slight excess of ammonium hydroxide. The excess of ammonia is boiled off. To this sufficient quantity of silver nitrate is added when a white precipitate of silver salt is obtained. The precipitate is separated by filtration, washed success..

Most of the oxygen is transported in a combined state. Some of the oxygen is present in solution in the blood. For each decilitre of blood, 4.6ml oxygen enters the blood in the lungs. Of this only 0.17ml remains in the plasma in the solution form. Remaining enters the..

In different regions of the body, the epithelium, particularly the ciliated epithelium, is involved in the transport of substance..
