1,122 words... slightly negative and the other end of it is slightly positive. The Dispersion forces exist between non-polar molecules. Dispersion forces are another of van der Waals' three forces. They exist between non-polar molecules. It is important to remember that within a bond, electrons are constantly MOVING. They zoom around the atoms really quickly. As a result, there may be a tiny instant in that time span where the electrons happen to dominant on one side, rather than the other. However, this t...

Rate Of Reaction Hydrogen Bonding
2,165 wordsRESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

Studies Have Shown Blood Vessels
1,197 wordsBiological regeneration has been studied over the years, in salamanders, and biological imitations of life. Through research on the mitotic capabilities of certain animals, to the DNA and hormones that make regeneration possible, scientists are slowly finding a way so that humans can regenerate lost or missing limbs, or grow organs used to save millions of lives in the future. Because being able to reproduce a limb or body part is dependent on nerves, scientists have found it vital to perform es...

E T C Plasma Membrane
448 wordsThe way in which a membrane is assembled decides what is allowed in and out of a cell and how it advances through the cell membrane. Certain molecules can simply pass through the cell membrane through diffusion. Diffusion is a type of passive transport meaning no energy is used for the substance to enter or leave the cell. Another way for molecules to enter the cell is through facilitated diffusion. When a molecule is simply to large to diffuse through the cell membrane it can enter the cell thr...

Grand Rapids Michigan Michael Jordan
1,570 wordsNanotechnology is actually a fairly new idea. This may not seem like any big deal in terms of ethics, but just like any type of scientific advancement there are positives and negatives. Of course the ethical issues don't stem out of just the fact that this is a new kind of science. It branches off of "what will this new scientific technology be used for?" For example, Embryonic Stem Cell research. It's not the research that's bad it's how they get the cells. There are half a dozen, maybe more, d...

Hydrogen Peroxide Degrees Celsius
539 wordsCatalase Which Is Found In The Liver' Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme, it fits into a depression on the surface of the enzyme molecule. This depression is called the active site. The reaction then takes place and the molecules of product leave the acti...

Ozone Layer Ultraviolet Rays
962 wordsThe Problem The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the suns ultraviolet radiation to reach the Earths surface. In particular, it will be the increase of UV-B rays which will have the...

Ultraviolet Rays Uv Rays
633 wordsThe ozone layer shields the earth from most of the harmful radiation and light comming from the sun. The ozone reflects and absorbs the ultraviolet rays that try to come in. Without this kind of protection, all living things will be effected by these UV rays. Skin cancer develops in most living mammals as a cause of an overabundance of the suns ultraviolet rays. The ozone layer is located in the earths stratosphere. The ozone layer is located from about fifteen-to-thirty kilometers above the ear...
