The purpose of the lab was to investigate osmosis‚ which was successfully achieved because there was a change in the potato’s mass which was due to the net movement of water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel

In this experiment‚ we had to demonstrate the process of osmosis using potatoes‚ and to determine the concentration of the cytoplasm of the potato. To demonstrate this‚ we had 6 test tubes and poured in different sucrose solutions of the following concentrations: 0.0M‚ 0.1M‚ 0.2M‚ 0.5M‚ and 1.0M. Once added in with all the sucrose solutions‚ we added in the 6 cylindrical potatoes of equal diameter and length. Before and after putting it in the potatoes‚ we had to weigh the initial and the final mass

Kidney Cancer Every year 14‚240 people die from a disease known as kidney cancer. So today we’re gonna learn what are the main causes‚ how is it diagnosed‚ what are the symptoms‚ and how to treat it. Kidney cancer is a disease in which kidney cells become malignant and grow out of control‚ forming a tumor. These first appear in the lining of tiny tubes in the kidney and as time passes it grows and grow until death; This was discovered and named by Greek physician Hippocrates (“Father of medicine”)

Kidney stones are solid lumps of crystals that are separate from urine‚ and they build up on the inner surfaces of the kidneys. Kidneys are the bean shaped organs‚ in the middle part of the back. Each kidney is located in either side of the spine‚ just below the rib cage. Kidney stones can sometimes be undetected. You might not even know you have them‚ until it tries to come out of the urinary tract. Kidney stones have many symptoms. Some of which are: horrible lower back pain‚ pain in the rib

and Acute Diseases Kidney Disease Kidney disease is known as kidney damage or decreased kidney function‚ and can result in kidney failure. Untreated it can kill you. Signs and Symptoms. These are symptoms of kidney disease. One sign is high blood pressure‚ another is sweat crystalizing on your skin. People with kidney disease also have a higher chance of cardiovascular disease. Another symptom is increased protein in your urine. Causes There are three main causes of kidney disease. They are diabetes

transport of materials in three semi-permeable membranes: dialysis tubing‚ eggs‚ and onion cells. Background Information 1. Diffusion is the movement of solutes from high to low concentration. Osmosis is the movement of water from low to high concentration. Both refer to movement in/out of a cell‚ but osmosis refers specifically to water. 2. Isotonic‚ hypertonic‚ and hypotonic all refer to the comparison of concentrations of solutes in verses out of the cell. Isotonic is when the concentration in

Kidneys Functions and Mental Health Stability The human body has several important organs‚ one of those organs are kidney. The kidney are two organs shaped as beans. The kidney size varies according to the individual age‚ sex‚ and health. They are located under the rib cage towards the back. According to the National Institute of Diabetes and Digestive and Kidney Diseases (Kidney Disease Basics 2012)‚ the kidney main function is to balance the amount of sodium‚ potassium in the body‚ water‚ disposed

Americans (Hispanic or Latino Populations‚ 2015). Each of these conditions is a type of kidney disease in which the kidneys cannot effectively filter wastes from the blood. Chronic Kidney Disease‚ or CKD‚ can lead to many severe health problems. Because the kidneys filter the blood‚ CKD can cause the body to retain fluid that can lead to swelling‚ high blood pressure‚ or fluid in the lungs (National Chronic Kidney Disease Fact Sheet 2014‚ 2014). CKD can also cause potassium levels to rise to dangerous

Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered
