a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent‚ each containing different concentration levels‚ then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell‚ but there is no net diffusion of water. Water will move in one direction or

Photography Write-Up: Separation The camera I use has been rented from the ERC on a regular basis‚ and is a Canon 600D or 700D. The photo’s i’ve captured for this project were shot on the standard lens‚ with a variety of settings. I also often use a mini LED light with a daylight filter in order to create more depth in the shadows in my images‚ I usually place this somewhere away from the camera in order to create angled shadows instead of images being frontlit. To start this project‚ I experimented

Plasma membranes are selectively permeable. The purpose of this experiment is to reveal how a form of diffusion in a semipermeable membrane works by creating a real life simulation of a semipermeable plasma membrane. This is done by building an imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This

Emily Shiang 6/27/13 POW Write-up In this POW write-up‚ I am trying to prove that there can be only one solution to this problem‚ and demonstrate and corroborate that all solutions work and are credible. What the problem of the week is asking is that the number that you put in the boxes 0-4 is the number of numbers in the whole 5-digit number. For example‚ if you put zero in the “one” box‚ you would be indicating that there is zero ones in the number. Another example is if you put a two in

Service Activity Write-Up 1. The program specific learning opportunity that I attended was the CONHCP Health Care Professional Panel. Although it was advertised that athletic trainers‚ health care administration professionals‚ and nursing professionals would speak at the event‚ only nursing experts were present. If there were more healthcare professionals available‚ information relating to the medical field would be more variated. Regardless of the limited number of experts‚ the nursing experts strived

Simple diffusion The term simple diffusion refers to a process whereby a substance passes through a membrane without the aid of an intermediary such as a integral membrane protein. The force that drives the substance from one side of the membrane to the other is the force of diffusion. In order for substances to pass through a cell membrane by simple diffusion it must penetrate the hydrophobic core of the phospholipid bilayer. The types of molecules that can do this are themselves substantially

The Effect of Molecular Weight and Time on the Diffusion Rate of Potassium Permanganate‚ Potassium Dichromate‚ and Methylene Blue.1 Arantxa Alex Carpio Group 1 Sec. X – 4L March 24‚ 2015 ABSTRACT The effect of molecular weight and time on the rate of diffusion was determined using the agar-water gel test. A petri dish of agar-water gel with three wells was prepared and a prepared solution of each substance was dropped on each well; one with potassium permanganate (KMnO4)‚

Sean Jones who portrayed Mickey used various techniques to show contrast throughout the stages of Mickeys life beginning at the age of seven up to dying around eighteen. !To begin with Sean was very active and typically energetic as a young child. By his tone and pitch constantly increasing we perceived how juvenile he was. Sean also used expressive and exaggerated words to show his youthful eagerness. When in trouble Sean portrayed this by dragging his feet‚ making slow strides
