rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water.

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

Oil Crisis When thinking about the 1970s‚ many words such as hippy‚ lava lamps‚ and tie-dye come to mind. However‚ there was much more going on during this decade than that. The 1970s‚ for those who lived in it remember having to wait in long lines at gas stations due to gas shortages. This became known as the oil crisis‚ which occurred in 1973 and 1979. Both of these crises caused a recession. As this comes with any recession‚ households and firms became uncertain about the future and weary of

Treatment of Antibiotic Pharmaceutical Wastewater Using a Rotating Biological Contactor One of the treatment of the wastewater is the treatment of antibiotic pharmaceutical wastewater using a rotating biological contactor. For your information‚ Rotating Biological Contactors (RBC) are effective for treating wastewater‚ while they are rarely reported to be used for treating antibiotic pharmaceutical wastewater (APW). Next‚ the biological treatment processes have been widely used in wastewater treatment

and regulations to individual cities and states. Some of the risks that come with getting a tattoo; infection at the site of the tattoo‚ allergic reaction to the tattoo dye‚ the spread of disease such as HIV and Hepatitis C‚ granulomas‚ and keloid formation. A tattoo is a series of puncture wounds made with a needle that carries dye into different levels of the skin. Infections can occur when a tattoo parlor does not use proper sanitation procedures. In 1992 the tattoo industry created the Alliance

DNA Extraction from Wheat Germ and Making an Agarose Gel AIM: To be able to make and agarose gel and perform gel electrophoresis in six different dyes. Also‚ to extract DNA from wheat germ. INTRODUCTION: Agarose gel is a substance that is used in science for gel electrophoresis and size exclusion chromatography. These processes use agarose gel to separate and analyze proteins and DNA. The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled

FILM STRUCTURE FILM STRUCTURE What is motion picture film? The American National Standards Institute (ANSI) describes it as “a thick flexible strip of plastic‚ complying with a dimensional standard as defined within‚ whose use is specific to the process of manufacturing a motion picture.” That definition leads to about a dozen pages of further definitions about various aspects of motion picture film. For our purposes‚ let’s take a look at how film is made‚ and how an image is formed on that film. THE

because when you move the beaker the water moves to messing up the pigments. 5. You could take several dyes with different affinities to the same liquid then compare them after the paper chromatography experiment. To determine the presence of a specific dye you could make a chromatograph of the specific dye and compare it to the chromatograph of a die that is suspected to have the specific dye in

to an arbitrary datum such as the base of the tank) and the pressure head at each piezometer. Also measure the water and sand levels (relative to your datum)‚ and the dimensions (length‚ depth and width) of the tank. 3. By injecting a small dose of dye just below the surface of the sand (against the glass) on the upstream side‚ trace the path of the flow line by marking its movement with time on the glass. 4. Observe the change in velocity of the flow as it travels from the upstream sand surface
