2013/2014 Assignment 1 (10 marks) Answer ALL the questions. 1. Discuss briefly fluid mosaic model for membrane structure. (6 marks) Answer: The lipids and most of the protein in the plasma membrane are free to bob about‚ sliding from one location in the membrane to another. Because lipids and proteins move about laterally within the membrane‚ the membrane is a fluid mosaic of lipids and proteins. The membrane fluid is since the composition of any location on the membrane can change. In the same

Chronic kidney disease (CKD) often presents with a "subtle" clinical presentation (Buttaro‚ Tybulski‚ Polgar Bailey‚ & Sandberg-Cook‚ 2013‚ p. 766). Therefore‚ clinicians need to be aware of the risk factors for CKD and screen patients who present with such factors that place them at risk for this condition. This paper will review the clinical presentation‚ diagnosis‚ patient history‚ physical exam‚ and diagnostics associated with the recognition of CKD. Treatment options will be discussed with

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

Water Balance Adipose tissue is one of the most hydrated of all tissues in the human body. False The most abundant cation in intracellular fluid is sodium. False Electrolytes determine most of the chemical and physical reactions of the body. True Solutes‚ regardless of size‚ are able to move freely between compartments because water carries them along the osmotic gradients.False The thirst center in the brain is located in the hypothalamus.True Dehydration can be caused by endocrine disturbances

Fluid and Electrolytes Study Guide -Fluids and Electrolytes move between interstitial fluid (surrounds the cell) and the intravascular fluid (blood plasma‚ capillaries). -Intracellular Fluid: -Extracellular Fluid: -Interstitial Fluid -Intravascular Fluid -Transcellular Fluid -Filtration: movement of water and smaller molecules through a semipermeable membrane. it s promoted by hydrostatic pressure‚ lack of this will call edema and unable to concentrate urine -Diffusion: from a high concentration

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because

Imbibition in Kidney Beans * Aim of Experiment: * To investigate the effect that emersion in salt solutions has on imbibition in kidney beans. * Safety Considerations: * One must use extreme caution when working with chemicals. Always wear protective goggles and gloves when handling them. KCl is slightly hazardous in case of skin contact‚ eye contact‚ ingestion‚ or inhalation. In case of eye contact‚ immediately flush eyes with plenty of water for at least 15 minutes. Seek

joints‚ which means that they have a cavity in the joints that contains synovial fluid. Joints are not just made of bone‚ because if they were‚ friction would keep them from moving smoothly. The body uses cartilage and the synovial fluid to reduce friction in joints. Osteoarthritis happens when cartilage wears away over time and exposes bone to bone and increases friction‚ which is very painful. Synovial fluid is a fluid-like material that is present in many of the joints of the body. It serves the
