Effects of the Bottleneck and the Founders effect Cecil Smith GS102 Grantham University Online The bottleneck effect happens when something of a great devastation has happened‚ causing a great amount of people to lose their lives and leave behind very few people at the most. The bottleneck effect happens at random and can kill of a whole population and with it can also wipe out the gene pool by doing so. An example of the bottleneck effect would be something like a tsunami‚ or an earthquake‚ which

3.2.4 Genomic DNA extraction of the root tips After the treatment of the onion bulbs with lake water sample at different period of time‚ the DNA from the root tips will be ready to be extracted and observed. First of all‚ the genomic of the Allium cepa will be easily done by the already available Uneasy® Plant Mini kit (Qiagen‚ Germany) in the laboratory. All of the procedures can be performed by referring to the manual provided by the kit. A very small amount of root tips that weigh 100 mg will

on on studying DNA by using a technique called X-ray diffraction. Her expertise was the X-ray diffraction mostly of proteins and lipids in a solution on DNA fibers. Franklin and a student‚ Raymond Gosling‚ took pictures of DNA and made the observation that there are two forms of DNA; the “A” form‚ which is dry and the”B” form‚ which is wet. One of their pictures of this observations‚ known as Photograph 51‚ became famous and was analytical evidence in discovering the structure of DNA. the photograph

What effects do mobile phones have on people’s health? November 2006 ABSTRACT This is a Health Evidence Network (HEN) synthesis report assessing the clinical effects of daily exposure to mobile phones in general populations. It addresses the impact on developing head and brain tumours‚ other morbidity-related outcomes and summarizes the biological effects of RF and microwave radiation. The report shows that the evidence available does not provide a clear pattern to support an association

GREENHOUSE EFFECTS IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases‚ and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere‚ it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to

Short-Term and Long-Term Effects From Nuclear Radiation on the Human Body Lately‚ nuclear energy has been in the minds of the American populace. With the recent collapse at the Hanford site and the recent testings of rockets by North Korea that could potentially carry nuclear warheads‚ concern has been raised about what the consequences of nuclear energy could be‚ especially on earth and the human body. One of these risks is radiation. No matter how negligible the risk of nuclear weapons and meltdowns

The Photoelectric Effect Definition: It is the emission of electrons from a metal surface under the illumination of a suitable radiation. The photoelectric effect is the phenomenon whereby electrons are emitted from a surface (usually metallic) upon the exposure to and absorption of electromagnetic radiation‚ such as visible light‚ that is above the threshold frequency. This is because electrons cannot get enough energy to overcome their atomic bonding. The photoelectric effect furthered wave particle
