Constructing Plant Phylogeny Based on Morphological Characteristics and Molecular Data Phylogeny is the study of evolutionary relationships among groups of living and extinct organisms on earth (Campbell et al.‚ 2011). To show evolutionary relationships‚ a phylogenetic tree (a visual representation of the lineages among organisms) is constructed. All phylogenetic trees are hypotheses that are to be tested‚ modified‚ and tested again. One type of tree‚ known as a

Titration CalculationsBefore you go any further‚ check that you can do the following… Calculate: Relative molecular masses from a given chemical formula Calculate: Number of Moles from the mass/RMM equation Manipulate: The number of moles equation to get the form you require. When you are confronted by a Titration calculation the first rule is: DON’T PANIC! The Second rule is read through the question very carefully.The Third rule is read through the question carefully again! We are now going to

some procedure of analysis‚ perhaps in the form of a practical application of knowledge to a range of tasks. What is the "subject" of the present study? It is not some clearly defined topic such as the behaviour of a certain kind of animal or the molecular structure of certain chemicals. The subject is a verbal phenomenon‚ or - to be very cautious - a possible verbal phenomenon. Do the titles of poems by Goethe and the German Romantics in which the word "Wandrer" occurs and do occurrences of the verb

Introduction A sample of DNA found in a crime scene was provided along with five suspects. Their DNA was then processed using restriction enzymes and Agarose Gel Electrophoresis. The objective of this lab was to match a criminals DNA to a crime scene using restriction enzymes EcoRI and Pstl with Agarose gel electrophoresis. Restriction enzymes cut DNA at a specific base pair site recognized by the enzyme‚ which then turns one single strand of DNA into many fragmented strands of DNA. EcoRI recognizes

Lab 2 Report for MATSE 473 Determining Molecular Weight using Solution Viscosity Name: Mengfang Li Group D Lab Partners: Michael Lorenzo‚ Peter Mcclure 01/24/2012 Introduction: This lab was designed to demonstrate the method to measure the intrinsic viscosity of the prepared polystyrene. Intrinsic viscosity‚ which is measured from the flow time of a solution through a simple glass capillary‚ has considerable historical importance for establishing the very existence of polymer molecules

Objective: To determine relative molecular mass of a soluble base‚ X2 CO3 by carrying out an acid-base titration with the following reaction ‚ knowing the amount of hydrochloric acid used and the amount of substance Z used. Hypothesis: The X in substance Z is a group 1 element because substance Z is a soluble metal carbonate and would most likely be sodium or potassium because these elements are commonly used. Materials 100 cm3 beaker‚ 250 cm3 beaker‚ 250 cm3 volumetric flask with stopper

Chemistry IA How does the molecular mass of alcohols affect its rate of evaporation? Introduction Alcohols are some of the most important molecules in organic chemistry. They can be converted into many different types of compounds. Alcohols contain the hydroxyl functional group (-OH)‚ bonded to a carbon atom of an alkyl or substituted alkyl group. The weight of the different compounds will differs because of the amount of hydrogen bonding. There are three kind of alcohols‚ primary‚ secondary

Email:209512772@ukzn.ac.za Abstract Calicophoron species were collected from the ruminants of cattle from a Kokstad abattoir in South Africa. The second internal transcribed spacer (ITS-2) of the ribosomal DNA had been used as the genetic marker in this molecular study. In an attempt to identify as
