Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water to move

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):

Week 3 Detecting Media Bias This story was about health care cost and the coverage available to people with pre-existing conditions. How if people have cancer or Multiple Sclerosis that insurance companies in some states can raise the rates on premiums. This can keep people from being able to afford it any longer. The medical costs of treating Multiple Sclerosis were as high as $27‚000.00 a year for an individual in 2007‚ according to the National Multiple Sclerosis Society (Young‚ 2012). Ann

oxidation-reduction reactions. The first part of the experiment measures the standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the theoretical and the experimental standard electrode potentials. The sources of error are incorrect solution preparation and contaminated materials

ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution: A.) W=( 2.2x10^4N) ( 7.6 m) W= 1.6x10^5 Nm or J B.) Positive‚ because the force on the system is positive. 3.
