happens‚ treatment is needed to replace the work of your failed kidneys. 4. How does dialysis give temporary relief to kidney patients? Dialysis may be either temporary or permanent‚ depending on the person. If a dialysis patient is waiting on a kidney transplant‚ the procedure may be temporary. However‚ if the patient is not a good transplant candidate‚ or a transplant would not alleviate the condition‚ dialysis may be a life-long routine. 5. When can memory be temporarily obliterated?

Under microscope‚ chloroplasts (green organelles) in Elodea tend to bound to the cell wall in pond water‚ spread all over the cell in distilled water‚ pull away from cell wall in 20% NaCl. In our last experiment‚ we use a dialysis bag that contains 30% glucose and starch solution then place into a beaker of water and iodine solution. We then remove the bag out of the beaker‚ and use two test tube which label BAG‚ BEAKER to perform a Benedict’s test. We place solution in the

Popliteal aneurysms are swelling of an artery. They are thought to be caused by atherosclerosis. These aneurysms are also correlated with the causes that develop aortic aneurysms. The wall of the popliteal artery is weakened‚ and thought to be because of inherited factors. In patients with multiple aneurysms in different arteries‚ it is theorized that there is an underlying weakness in the tissues. The exact nature of this has not been clarified at this time. Possibly the propensity of the

Osmosis Rates in Artificial Cells Daniel George Department of Biology Grand Valley State University 1 Campus Drive Allendale‚ MI 49401 georged@mail.gvsu.edu Abstract The lab for this paper was conducted for the topic of osmosis‚ the movement of water from high to low concentration. Five artificial cells were created‚ each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic‚ hypotonic‚ or isotonic solutions for a period of 90

Graft and corruption are the charges that are typically levelled at highly-placed government officials‚ who are able to use public funds to improve their own fortunes due to increased access‚ influence‚ knowledge or power that comes with an elevated position. Graft and corruption is a grave political problem in the Philippines

Lab Report 1: Cell Transport Mechanisms and Permeability Using PhysioEx 8.0 Introduction The purpose of these experiments is to examine the driving force behind the movement of substances across a selective or semiperpeable plasma membrane. Experiment simulations examine substances that move passively through a semipermeable membrane‚ and those that require active transport. Those that move passively through the membrane will do so in these simulations by facilitated
