Introduction: The purpose of this lab is to apply Mendel’s laws to predict the probability of the occurrence of a single event‚ of two independent events and of certain traits in offspring of parents exhibiting traits. Gregor Mendel was an Austrian monk in 1866‚ who studied how traits were passed using pea plants. From his studies of inheritance‚ he created three laws of inheritance: the law of dominance‚ the law of segregation‚ and the law of independent assortment. He called genes ‘’factors’’

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Shalacia Gilmore Fall 2012 BIO 1107 Natural Selection Lab INTRODUCTION In the 1850s‚ two scientists by the name of Charles Darwin and Alfred Russell Wallace composed the theory of evolution by natural selection. (1) Darwin characterized several claims needed for natural selection to happen‚ including heritable variation within the population‚ and the presence of more individuals than the environment can support. They also discovered that certain environments favored certain traits. These

Kimberly Correa Forensics Dr. Edmond Locard was a pioneer in forensic science who became known as the Sherlock Holmes of France. He formulated the basic principle of forensic science: "Every contact leaves a trace". This became known as Locard’s exchange principle. Born on November 13 1877 in Saint-Chamond‚ France‚ Locard studied medicine and law at Lyon‚ eventually becoming the assistant of Alexandre Lacassagne‚ a criminologist and professor. He held this post until 1910‚ when

Spinach was dehydrated using ethanol‚ and the pigments were extracted with dichloromethane. The spinach extracts were dried using CaCl2. Then‚ the solid pigments were run through a column using a non-polar solvent‚ hexane

quick results the PCR method is ideal because results can be obtained within just a few hours (often as low as within five hours). Getting these results in such a timely manner can help to start treatment earlier‚ reducing the amount of time needed for isolation and hospitalization‚ and thus reducing costs. It has also been shown that the PCR method is not only quick but it provides the most reliable results. In a study comparing conventional methods with PCR it was shown that the PCR method is preferred

criminal activities or any natural disaster are very well portrayed by Forensic Science. This far-fetched science lends a hand in investigating and delivering judgment for criminal or civil cases and identification of an individual during these proceedings. These days we consider forensic odontology very much reliable and trustworthy method of identification of the deceased‚ particularly in several fatality incidents.
