Umbilical Cord Upper Lip
1,360 wordsFetal development starts with the process of fertilization. It starts when the female ovulates producing an egg. This egg then travels into the fallopian tube where it waits to be fertilized. Once sperm enter the body they must travel up the uterus until they make their way up to the egg. Once at the egg the sperm try to get in. They sperm wiggle their tails until they make it in. Once it makes it in the egg will not any other sperm in. The sperm that made it then drops its tail. After about twe...

Amount Of Light Five Minute
482 wordsDetermining Rates of Photosynthesis Through Chloroplasts 2) Purpose = measure the rate of photosynthesis in chloroplasts. 3) The chloroplast will be subjected to two experimental conditions- light, and the absence of light, using a spectrophotometer to determine the amount of DPIP reduced at specific time intervals under each condition. 4) I predict the amount of DPIP reduced will vary for each condition and increase over the time intervals. I hypothesize under the light condition the amount of ...

Biology Lab Report Genetic Exchange In Prokaryotes
679 wordsThis lab deals with the process of genetic exchange in prokaryotes. There are three main mechanisms of genetic exchange which include transformation, transduction, and conjugation. In transformation, DNA is released from cells in the surrounding environment which is then incorporated into the recipient cells DNA. In transduction, DNA is transferred through a virus to the recipient. In conjugation, genetic exchange occurs through direct contact with another cell and the plasmid is transferred fro...

Unborn Baby Legal Abortion
1,007 wordsAbortion means expulsion of a fetus from the womb before it is able to survive. It is generally illegal. It is an issue that evokes, on all sides, very strong feelings and judgments and very heated recriminations. The most radical formulation of the anti-abortion or "pro-life" side of the debate views abortion as the murder of unborn children, and so as the equivalent of out and out infanticide, making the legal use of abortion. Legal abortion is an abortion that allowed by the law. Some country...

Many people dont realize what the computer evolved from, and the speed at which computer technology has taken to arrive to what it is today. The earliest know computer is the abacus, invented by the Chinese in 2600 B. C. Not many people consider this to be a computer, but by definition, it is. One of the more recent early computers was built by Herman Hollerith, who invented a mac...

Begin To Develop Pituitary Gland
1,294 wordsNovember 16, 1995 Hundreds of thousands of times a year a single-celled zygote, smaller than a grain of sand, transforms into an amazingly complex network of cells, a newborn infant. Through cellular differentiation and growth, this process is completed with precision time and time again, but very rarely a mistake in the 'blueprint' of growth and development does occur. Following is a description of how the pathways of this intricate web are followed and the mistakes which happen when they are n...

Investigation On The Enzyme Trypsin
2,197 wordsAn Investigation determining a factor affecting the rate of digestion of gelatin by the protease trypsin. Introduction An enzyme is a biological catalyst, which speeds up reactions. An example of this in the human body is trypsin (a protease produced in the pancreas and used in the stomach), which catalyses the digestion of gelatine, a protein. For this investigation, a photographic film will be the source of the gelatine. I will be able to identify when the gelatine is digested, when the photog...

From this association ultimately would come a lawsuit, considering attempts to get patents for a commercial version of the machine that Mauchly built. The suit was finally decided in 1974, when it was decided that Atanasoff had been the true developer of the ideas required to make an electronic digital computer actually work, although some computer historians dispute this decision. But during the...

Speed Of Light Degrees Celsius
1,124 wordsThe Properties of Light Applied to Fibre Optics One of the basic properties of light is that it travels in straight lines and can have it? s direction changed. This is the property which is applied to achieve the purpose of Fibre Optics which is to carry light from one place to another. The way this is done can be explained by the principle of refraction. This is the principle which governs the behaviour of light as it passes from one transparent substance to another. It states; if a ray of ligh...

347 wordsThe density of air In this experiment we are to measure the density of air. It is a quite simple experiment, you learn how important it is to measure exact and be aware of the sources of error when measuring such small quantities. The whole idea is that you know the mass of a certain volume of air, and then measure the volume. A digital scale that shows two decimals measures the first variable. We simply took a plastic bottle, weighed it when the lid was open, then with the help of a compressor,...
