TITLE PINEAL GLAND: “THE HIDDEN EYE” INTRODUCTION The third eye‚ also referred as parietal eye or pineal eye‚ is a photosensory organ that triggers hormone production and thermoregulation. This eye cannot see in quite the same way as the main eyes‚ instead only detecting shapes and shadows rather than full pictures. They are also highly sensitive to changes in light and dark – producing markedly different hormones based on time of day. It produces melatonin‚ a hormone that affects the modulation

The Purity and Purification of Solids Melting Point Lab Introduction: The point of this lab was to determine the eutectic point for the naphthalene biphenyl mixture‚ as well as determining the melting point of an unknown substance by comparing it with two known samples. Melting point is a temperature in which a substance changes from solid state to liquid state. Melting points are used to determine whether the given substance is pure or not. Substances that melt sharply‚ less than 1-2°C indicates

Mitosis and Meiosis I. These two processes function to pass chromosomes from one cellular generation to the next in a very carefully controlled manner. II. Mitosis and Meiosis are both correctly described as nuclear division; they are never correctly called cell division‚ or any kind of reproduction. It is possible (and often quite normal) for nuclei to divide when cells don’t. And organisms reproduce; nuclei and cells divide. III. Mitosis A. Mitosis is the division of a nucleus

A General Review of Tetracyclines Antibiotics Chang Liu Instructor: Prof. Jasson Sello Department of Chemistry‚ Brown University Providence 02906‚ RI Tetracyclines are the first broad-spectrum antibiotic to be applied to clinic use. Nevertheless‚ the increasing incidence of bacterial resistance of tetracyclines led to a series of studies on the development of semisynthetic tetracyclines to circumvent the resistant organisms. In order to better design the structures of tetracycline derivatives

for products such as computers. Scientists have succeeded in imaging and forming a unique bond between a single gold atom and a single organic molecule called a pentacene. They managed to bind the atom to the pentacene and take images of rearrangements of the electrons participating in the formation of the chemical bond. The pentacene has been selected as it is a special class of molecule that has qualities of particular use in molecular electronics. The gold atom is a metal atom that

Julio Hernandez Genetic Mutation is a change of the nucleotide sequence of a genome. Mutations result from un-repaired damage to DNA or RNA genomes usually caused by radiation or chemical mutagens or from errors in the process of replications. Mutations play a part in both normal and abnormal biological processes‚ including evolution‚ development of the immune system‚ and cancer. There are two main types of genes that play a role in cancer‚ ocnogenes and tumor suppressor genes. An important
