the null hypothesis for weight change because weight is not impacted by temperature. The statistical test used results that did not show that the lipid bilayer portion of the membrane of living cells is not permeable like the dialysis membrane used in the lab. The dialysis membrane used in the lab is permeable to small ions like Na+ and Clˉ. The experiment was also performed in a “closed system” which is not reflected in the statistical test. The results of the statistical test does however support

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

kidneys. 4. What are possible treatment options‚ and what is the prognosis? Treatment usually means hospital stay‚ because there needs to be a balance in the amount of fluids in the blood and medications to control blood potassium. Dialysis will need to take place in order to remove toxins from the blood. Until her kidneys recover‚ she will need to control her diet so her kidneys do not have to filter too much or work to hard.

III. Medical Treatments Bones are designed to naturally correct on their own‚ however surgery or means immobilization is often required to make sure the bones are aligned properly when healing. Medical treatment depends on the severity of the break. There are several categories of bone fracturing‚ they are: 1. Hairline fracture- a thin small stress fracture often occurring in the leg. In the case of this injury‚ a splint and cast are the only medical means necessary for repair. 2. Greenstick

that require bone-graft procedures (Yaszemski‚ 1994) and still escalating annually. As a result‚ it had become one of the major concerns in countries like the USA and Europe. Hence‚ bone tissue engineering continue to progress as an interdisciplinary field as it addresses the increasing need of bone defects obtained by several circumstances (i.e natural birth and accidents). Currently‚ defects on bone tissues were treated with several autologous bone grafts‚ autogenous bone grafts or as an alternative

Aneurysms were first described by the 16th century anatomist and physician Vesalius‚ who believed they were simply a widening of the vessel (Collin et al 2009). An abdominal aneurysm (AAA) is a condition in which the abdominal aorta (a large blood vessel that supplies blood to the abdominal‚ pelvis and the lower limbs) becomes large and ballooning leading to the development of several symptoms. The condition more often occurs in males compared to females. It occurs more frequently in above the age

Horseshoe Kidney The human body is a wonderful thing. It ’s not everyday that one takes a second to ponder about all of the wonderful things the human body can do. The brain helps us to be the most intelligent beings on earth. Our hearts beat to keep us alive. What about the kidneys? People typically do not think about what they do for us or consider them one of the human ’s most amazing organs. What if humans only had one kidney? Would there be any disadvantages compared to the typical human
