HOW DOES DISEASE AFFECT THE LEVEL OF ORGANIZATION? * THE KIDNEY There are two kidneys‚ each about the size of a fist‚ located on either side of the spine at the lowest level of the rib cage. Each kidney contains up to a million functioning units called nephrons. A nephron consists of a filtering unit of tiny blood vessels called a glomerulus attached to a tubule. When blood enters the glomerulus‚ it is filtered and the remaining fluid then passes along the tubule. In the tubule‚ chemicals and

Lab Report #1 Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport is called active process which uses ATP energy to transport substances through the membrane. The other method is called passive process which does not require the use of ATP energy. During passive processes

that once a plant reaches a certain acidity within its own body the growth will start to decline. This decline in growth could be due to the fact that a more acidic environment causes the plant to react to try and bring the plant to its desired homeostatic pH. The extra energy expended during trying to reach a certain desired plant pH caused a decline in growth because of how the energy was refocused on homeostasis. With a given opportunity to test this experiment again I would dissect a portion of

PURIFICATION OF LACTATE DEHYDROGENASE FROM CHICKEN MUSCLE TISSUE Abstract The enzyme lactate dehydrogenase (LDH) catalyzes the last step of anaerobic glycolysis that is important for the normal function of the body. Purification of LDH is essential to understand its structure and function. The purpose of this experiment was to extract and purify LDH enzyme from chicken muscle tissue using a variety of various. Analytical methods such as activity and protein assay were employed to determine

Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker

The first lab will investigate the movement of glucose and starch across a selectively permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors

cysts can profoundly enlarge the kidneys while replacing much of the normal structure‚ resulting in reduced kidney function and leading to kidney failure. When PKD causes kidneys to fail-which usually happens after many years-the patient requires dialysis or kidney transplantation. About one-half of people with the most common type of PKD progress to kidney failure‚ also called
