The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the

Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth‚ above the cemento-enamel junction‚ it is also possible for caries to form on the root surface‚ below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental

light intensity onto the leaf’s surface and the surface area of the leaf. Hypothesis I think the light intensity could affect the surface area in the following way: ·A higher light intensity could make the surface area of the leaf larger. The reason I think a higher light intensity could make the surface area larger is the fact that there would be a larger amount of chlorophyll‚ containing chloroplasts‚ for photosynthesis. By having leaves of a larger surface area‚ there would be a much more efficient

DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

Diffusion is a natural act that takes place in the human body in order to utilize and absorb important concentrations into the body. In order to understand how diffusion works‚ it is important to understand how temperature plays a role. In connection with diffusion‚ a certain temperature must be obtained to begin the process. Introduction Diffusion is very important in the body for the movement of substances. An example would be the movement of oxygen from the air into the blood and carbon dioxide

This step largely follows the LED CUBE 3x3x3. We’ll need a total of 27 LEDs that will be grouped into three sets of nine. Each set of nine LEDs will share a common connection amongst their cathodes (negative leads). We’ll refer to each of these sets as a "level". Each of the nine LEDs on a level is connected to the corresponding LED on the other two levels through their anodes (positive leads). These will be as "columns". To start we’ll use a drill to create a jig out of a small piece of scrap wood

cultural diffusion‚ the limitation of spatial interaction‚ and space-time compression? Whilst reading “Globalization in a Bottle” and “The Tipping Point-- Three Rules of Epidemics” three key concepts of “Chapter One: Basic Concepts” become inherently apparent: cultural diffusion‚ the limitation of spatial interaction‚ and space-time compression. The two articles clearly depict these three theories‚ through their choice use of real world examples. In each of these articles‚ cultural diffusion is a

_____________________________________________________________________________ Agarose is a polymeric cross-linked polysaccharide extracted from the seaweed agar. Agarose is used widely in gel electrophoresis because it gels at a lower temperature‚ does not contain the inhibitors of virus growth frequently present in agar‚ and has more uniform pore size than that of agar. It is also easily poured and does not denature the samples. In agarose gel electrophoresis‚ DNA or RNA fragments are separated or isolated according

The Cube: Geometrical Shape or Death Machine? The Cube a movie directed by Vincenzo Natali and released in 1997‚ depicts six strangers awakening after being abducted in the middle of the night‚ trapped inside a giant mechanical cube fighting to escape‚ for survival‚ and against their own inner-demons. Each of the characters in the movie have drastically different personalities and a different skillsets. As the story unfolds‚ they understand that each individual skill is needed to help them escape
