  • Physical Nature Of The Molecular Signal
    2,206 words
    UNDERSTANDING DIGITAL BIOLOGY Explaining digital biology is impossible without explaining its principle. The purpose of this text is not to report experimental results. Rather, it tries to explain to laymen, in the simplest terms, this radically new approach to biology. We hope it will be useful to all, scientists or not, who find it hard to 'make the leap'. Indeed, is it possible to believe that the specific activity of biologically-active molecules (e.g. histamine, caffeine, nicotine, adrenali...
  • Water Isn't Soluble With The Oil
    609 words
    The Two-Faced Detergent Whether soil particles are attached to carpet fibers, wood floors or restroom sinks, they need to be removed. But how is this done? Most of us wipe or scrub a dirty surface with soap and water without a second thought about how they actually work to remove soil. The process of removing dirt begins at the molecular level. In order to understand how soap works, we must first acknowledge what soap actually does. By definition, soap is a mixture of sodium or potassium salts a...
  • Strong Hydrogen Bonds With Water Molecules 7
    1,035 words
    Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earth's thriving ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive one 1 (...
  • Water Molecules And Alcohol Molecules

    newspaper measuring cups 1 cup of dry cornstarch large bowl or pan food coloring (if you want) 1/2 cup of water Put newspaper down on your counter or tabletop. Put the cornstarch into the bowl. Add a drop or two of food coloring. (Use whatever colors you like.) Add water slowly, mixing the cornstarch and water with your fingers until all the powder is wet. Keep adding water until the Ooze feels like a liquid when you " re mixing it slowly. Then try tapping on the surface with your finger or a sp...
  • Equal To Avogadro's Number
    617 words
    A Vogadro A vogadro was born on June 9, 1776 in Turin, Italy. He began his career in 1796 by obtaining a doctorate in law and practicing as a lawyer for three years after. In 1800, he began to take private lessons in mathematics and physics and decided to make the natural sciences his profession. He was appointed as a demonstrator at the Academy of Turin in 1806 and the Professor of Natural Philosophy at the College of Vercelli in 1809, and in 1820, he was appointed the professor of mathematical...
  • Form Strong Hydrogen Bonds With Water Molecules
    805 words
    Water is Essential for Life Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. It's important to understand and examine the water molecule in order to ascertain how it brought about Earth's thriving ecosystem and how important it is for us today. Water is a strong solvent, it's a very unique molecule that can breaks and reforms constantly. Each water molecule consists of one oxygen atom and two hydrogen atom...
  • Total Mass Of A Water Molecule
    556 words
    Mass Spectrometer A mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The mass spectrometer then uses electric and magnetic fields to measure the mass (weight) of the charged particles. There are many different kinds of mass spectrometers, but all use magnetic and / or electric fields to exert forces on the charged particles produced from the chemicals to be analyzed. A basic mass spectrometer consists of three parts: 1. A source in which i...
  • Bonds Of A Disaccharide
    255 words
    Lisa Stephan BIO-105-E 4 October 9, 2003 Explain the role of dehydration synthesis and hydrolysis in the formation and breakdown of organic molecules. Give examples of each. The role of dehydration synthesis in the formation of organic molecules is to fuse two monosaccharides (simple sugars) together to form a disaccharide (double sugar). This synthesis reaction is accomplished by releasing a water molecule during bond formation. As a result, a disaccharide is formed from the two monosaccharides...
  • Humid Conditions
    329 words
    From the set of results I have discovered that the rate of transpiration is faster in windy conditions compared to humid conditions. In windy conditions the time taken for the bubble to move 100 mm was only 4 minutes when in humid conditions it took 13 minutes. In the control conditions it took 6 minutes. Transpiration is the loss of water vapour by diffusion through the stomata in the leaves. Several weather conditions affect the rate of transpiration including temperature, humidity, air moveme...
  • Hydrogen Bonds Between Water Molecules
    2,664 words
    Introduction Water is an essential ingredient for the existence of life as we know it. Biochemical processes occur in aqueous environments, many of which use water. Water also plays a significant role in the process of photosynthesis (6 CO 2 + 6 H 2 O + 672 kcal - C 6 H 12 O 6 + 6 O 2). Photosynthesis is the most basic and significant chemical reaction on earth, providing the primary nutrients, directly or indirectly, for all living organisms and is the primary source of atmospheric oxygen. With...
  • The Hydrogen Bonds Between The Water Molecules
    1,730 words
    Water is vital for life, with out water life on earth would cease to exist as every living organism must have water in order to survive. The total amount of water on Earth is fixed, (75% of the earth is covered in water) and most is recycled and re-used. The largest reservoirs are oceans and open seas. Very little is actually contained within living organisms, although water is a major constitute of most life forms. Water is a major component of cells, typically forming between 70 and 95% of the...
  • The Biological Importance Of Water
    1,087 words
    The Biological Importance Of Water""; The Biological importance of Water Generally, the main biological importance of water is that life cannot exist without it. In fact on a percentage basis, the majority of any organism is comprised of water. Additionally, it is believed that life first originated in the bodies of water on the earth. The importance of water is seen in such third world countries as Kenya. Where the inhabitants are forced to drink water so dirty and contaminated that they know i...
