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

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

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

As a nephrology nurse‚ I take care of patients with acute and chronic kidney disease. I constantly educating these patients about ways to promote their health and prevent any complication. For my dialysis patients‚ the primary education focus is teaching them the best methods to take care of their dialysis access “Fistula‚ Graft‚ or Central Hemodialysis Catheter”‚ fluid allowance‚ dietary restriction‚ medication adherence; and blood pressure‚ and glucose control.

In relation to this‚ an alternative option has become available for Dialysis patients called Nocturnal Home Hemodialysis (NHHD) within the past few years. This new method allows patients to complete treatments within their own homes privately. These patient’s self-administer hemodialysis “for 6 to 8 hours‚ 5 to 6 nights

Introduction There are many different factors that can influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that
