the first time gene regulation was demonstrated 1910 Thomas Hunt Morgan was the first to recognise genes are carried on chromosomes: the basis for modern genetics. He demonstrated the existence of sex-linked genes and expanded trait linkage using "crossing-over" 1911 Alfred Sturtevant‚ mapped the locations of several fruit fly genes. This was the first genetic map 1926 Thomas Hunt Morgan published the "theory of the gene" based on Mendelian genetics 1933 A new technique

OF VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile organic

assumptions of the Kinetic-Molecular Theory of gases.</i><br><br>a) Gases consist of large numbers of tiny particles. These particles‚ usually molecules or atoms‚ typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids.<br><br>Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared to liquids and solids‚ and the

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature‚ molecular weight‚ and movement. To test the rate of diffusion a drop of dark food coloring was added to a glass of tap water and it was timed to see how long it took for the drop to reach the bottom of the glass. This procedure was repeated three times to

1. DNA Nucleotide [pic] Nucleotides consist of three parts --- a pentose sugar‚ a nitrogen-containing base‚ and a phosphate group. A pentose sugar is a five-sided sugar. Deoxyribose has a hydrogen atom attached to its #2 carbon atom (designated 2’)‚ and ribose has a hydroxyl group atom there. Deoxyribose-containing nucleotides are the monomers of DNA RNA Nucleotide [pic] The left picture shows the nucleotide unit of RNA. Nucleotides differ from nucleosides
