However‚ EDTA and the EDTA-complex are both colorless compounds and so an indicator will also need to be used. In order to prepare for titration‚ 500 mL of approximately 0.004 M disodium EDTA solution is created by weighing 0.7761 grams of 〖Na〗_2 EDTA dissolved in approximately 500 mL of deionized water. The stock calcium ion and the prepared unknown water sample‚ Unknown # 7 are used to

A Study of Gene Mapping Using Tetrad Analysis in the Fungus Sordaira Fimicola BISC 302 Genetics Lab: Wednesday June 14 2006 ABSTRACT The fungus‚ Sordaria fimicola‚ selected for tetrad analysis due to its ease in observation of recombination events. These fungi have mutation in genes that control spore colour. Tetrad analysis can be conducted by crossing wild type spores with the two mutant types‚ tan and gray. Crossing wild type with the mutants can allow for direct observation of

Activity 3: “Using Sources” Emma Ballew Washington State University Tri-Cities For my lesson‚ I did “Using Sources”. 1) The first thing I learned was the 2 different ways to use sources to argue. The first way to use a source is by agreeing with the source (Atias‚ Lennard‚ & Zuckerman‚ 2013). This can be done in two ways. One way is to use the research that other sources have done (Atias‚ Lennard‚ & Zuckerman‚ 2013). Using the research of others can help to lay a foundation for a paper’s argument
