Laboratory Report on Urine Examination Introduction: When testing urine the test results may provide information regarding the status of carbohydrate metabolism and kidney function. The kidney glomeruli act as ultrafilters for the plasma protein; however as much as 150 mg/dl of protein may normally be excreted into the urine. In glomerular proteinuria‚ an increase in glomerular permeability occurs‚ resulting in an increase of urine proteins. High urine protein concentration therefore may indicate

General Anatomy and Physiology Case Studies - Osmosis These two Case Studies come from a National Center on Case Studies. I think that a case study approach is very useful in applying knowledge and this is what makes you learn it better. They may be a little daunting when you read them but I will help you go through them. Please ask for help so this topic becomes more enjoyable for you.

my aunt’s turn and when we went to eat the mashed potatoes they were super salty. After thanksgiving dinner that year I became interested in figuring out how the using the same recipes the outcome could be so different. Background Information: Osmosis is the of a solvent across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The water being the solvent can move across the membrane but the salt

concentration than itself‚ the potato chips lost weight. As there was a higher concentration of water molecules inside the potato chip compared to the concentration of water molecules outside the potato chip. It was stated in my prediction that osmosis is the diffusion of water molecules from a high to a low concentration‚ therefore water molecules from inside the potato chip moved out into the solution. Leading to the cytoplasm inside the cells to shrink and become flaccid. As the cells of the

or volume of the plant cells does not change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows

Lab 5: Osmosis Purpose: The purpose of this lab is to familiarize you with osmosis and‚ specifically‚ what happens to cells when they are exposed to solutions of differing tonicities. Hypothesis: If we add higher concentrations of sugar to the dialysis tubing‚ then the net movement of coffee into the dialysis tubing will increase. Materials scale or balance 24" dialysis tubing 4 transfer pipets sugar scissors rubber bands four coffee cups - they need to be roughly the same size

If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III.

Premium Osmosis Chemistry Concentration
The movement of water down its osmotic gradient across a selectively permeable membrane is known as osmosis. The difference in the concentrations of solutes on either side of the membrane results in the establishment of an osmotic pressure. Water follows the direction of solutes‚ this means that in the event where there are more solutes outside the cell than there are inside the cell‚ water will move from the inside of the cell to the outside in order to establish water balance. When a cell is placed

NAME: Donna Ha TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs INTRODUCTION: In order to fully understand the concept of this experiment‚ one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The

SCENARIO OF KIDNEY DISEASE IN INDIA Kidney disease is a hushed killer. Almost 12 per cent of India’s population is expected to be suffering from some form of undetected kidney disease‚ which can cause a total kidney failure that needs dialysis and transplantation. Only 9 per cent of the patients are able to obtain kidney transplant and pay for the treatment. As many people belong to the weaker socio-economic status it is difficult to undergo dialysis which costs around Rs. 1‚500 - Rs 2‚200 per session
