In this simulation‚ you can input the temperature and observe the spectrum of the radiation emitted. a) The temperature of stars in the universe

Blackbody radiation is the electro-magnetic radiation emerging from a small hole in a perfectly black box containing electromagnetic radiation at a high temperature. Scientists were interested in setting standards for the electric and thus measured the distribution of the total electromagnetic energy in a black box among the different wavelengths of the light. But not until Max Planck‚ at the turn of the century‚ was a single mathematical formula for the observed distribution of the energy among

DNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth‚ division‚ and function. DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). these nitrogen bases are bind with

if UV Radiation induced a mutation in the DNA of Serratia Marcescens and prevented the production of the red pigment called Prodigiosin. Hypothesis: Maybe the disappearance of red color in Serratia Marcescens is caused by the UV light which induces mutations in its DNA and is known as a common mutagen. Prediction: If UV light mutates the DNA of Serratia Marcescens then the red pigment colonies of the bacteria will no longer be produced. Independent Variable: Ultra Violet Radiation Dependent

For over a decade‚ there has been a controversial issue dealing with building a national DNA database. This issue has been brought up over the discussion of the actual database and what kinds of effects will come out of it‚ if it actually happens to go through. Some people think the database will be a force in crime fighting. Others think it is a violation of civil liberties. In the early 1900s‚ “fingerprinting‚” a new crime-fighting database‚ was developed. With the exception of identical

DNA sequencing From Wikipedia‚ the free encyclopedia [pic] The term DNA sequencing refers to sequencing methods for determining the order of the nucleotide bases—adenine‚ guanine‚ cytosine‚ and thymine—in a molecule of DNA. Knowledge of DNA sequences has become indispensable for basic biological research‚ other research branches utilizing DNA sequencing‚ and in numerous applied fields such as diagnostic‚ biotechnology‚ forensic biology and biologicalsystematics. The advent of DNA sequencing

one thing that unites us all‚ DNA. DNA‚ standing for Deoxyribonucleic Acid‚ is commonly compared to a blueprint. This blueprint orders a highly specific set of corresponding bases‚ which in turn codes for an amino acid. However‚ this specificity comes at a very high risk; a single error in a base could code for a completely different amino acid‚ causing a mutation that could devastate the organism. Recently‚ scientists have discovered a new method to edit and repair DNA that could hopefully complement

claims‚ and studies about the cellphone radiation exposure. Some studies suggest that there is no evidence that cellphone can cause cancer‚ others are saying that there are credible amount of evidence that the use of cell phone cause health complication including cancer. According to the article “Dangers of today technology” Recent research shows that cellular phones can cause health complication‚ including cancer. “Heavy long exposure to cell phone radiation increases risks for certain type of cancer

The discovery of DNA is attributed to the research of three scientists in 1951; Francis Crick‚ Maurice Wilkins‚ and James Dewey Watson. They were all later accredited with the Nobel Prize in physiology and medicine in 1962. Thanks to their discovery‚ science has been able to research and learn from DNA blueprints and use recombinant DNA technology to discover answers‚ vaccines and build immunity for many viruses. In recent years science has been using this new technology to genetically modify animals
