Comparison Between Light and Electron Microscope
The introduction of the microscope as a tool for the biologist brought about a complete reappraisal of the micro- composition of biological tissues, organisms and cells. In the infancy of its application to organic materials, it was the implement of anatomists and histologists in particular, where previously unimagined structures in cells were revealed. More recent developments in biological specimen preparation have come from biochemists and physicists who have used the microscope to examine cells and

Bombs Away: Different Reactions to the Vietnam War in Across the Universe
Bombs Away: Different Reactions to the Vietnam War in Across the Universe In the 1960s and 1970s, the Vietnam War claimed approximately 60,000 lives and sparked intense division of Americans who either supported or opposed the war. Others were indifferent but no one went un-affected by the conflict. Julie Taymor’s 2007 film Across the Universe demonstrates the reactions of two Vietnam-era characters and the distress it caused within their relationship and their lives. These two

The Wonderful World of Chemical Reactions
There are many types of chemical reactions, five general ones of which I will be describing. Chemical changes are a result of chemical reactions. All chemical reactions involve a change in substances and a change in energy. Neither matter nor energy is created or destroyed in a chemical reaction, only changed. There are so many chemical reactions that it is helpful to classify them into 5 general types, which include the following: synthesis, combustion, decomposition,

Determining Optimum Temperature and Ph for Enzymatic Reactions of Alpha Amylase
Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the

How to Picture Light
I don't know why, but I've never really 'understood' light, in general. I know all of the details, how lenses work, reflection, diffraction, refraction, parallax, blah blah, but overall I couldn't actually Picture it very well in my head. I won't go too deeply into light, there's a lot to it. There's colors and frequency and different reasons different things are different colors.

Rate of Photosynthesis
The rate of photosynthesis can be affected by sunlight, temperature, CO2 and O2, and any factor that influences the production of chlorophyll, enzymes, or energy carriers. The rate of photosynthesis will always correspond to that factor which is in least supply. Its rate will only increase when its supply is increased. An experiment on the effect of light intensity can be done to measure the rate of photosynthesis. You can expose samples of a plant

Wave Nature of Light
Wave Nature of Light Objective: The purpose of this lab is to investigate interference, otherwise known as the diffraction of light. A beam of light acts a wave, and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges, allowing light to enter an area of shadow. When waves are superposed, they reinforce each other when crests

Rate of Reaction
We are trying to find out if temperature affects the rate of reaction between Hydrochloric acid and Magnesium. I think that the higher the temperature of the acid rises, the rate of reaction will increase. For example: If I double or triple the reaction, the rate of reaction will also double or triple. As the liquid particles bash into the solid they may knock of a solid particle. This collision would therefore cause a reaction.

Rates of Reaction
Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur, the equation for this reaction is: Na2 S2 O3 + HCL, H2 O + NaCL + SO2

Why Is There No Light Bulb?
As we all know, a common ice-box in the kitchen is divided into two sections: the freezer, either at the top or bottom, and the refrigerator chamber, which maintains a temperature a few degrees above 0ўXC. Nearly every refrigerator chamber has a light bulb. However, we hardly ever find a light bulb in the freezer. So, what factor allows the installation of a light source in a refrigerator but not in a freezer? Whether to
