The Effect of pH on a Food Preservative September 18‚ 2012 Objective: To study the affect of pH on a food preservative. Chemical Equation: C6H5COONa + HCL ------ C6H5COOH + NaCl Procedure: This experiment was started with a clear solution of sodium benzoate and HCl was added to it‚ ultimately producing benzoic acid. First‚ .3395 g of sodium benzoate was weighed‚ then it was dissolved in water‚ causing it to disassociate into ions. Next‚ 3M of HCl were added drop wise to the solution

The Cell Cycle Brittany Jameson Vista College Abstract The cell cycle is made up of five steps. These steps are interphase‚ mitosis‚ cytoplasmic division‚ cell differentiation‚ and cell death. During mitosis there is a series of four stages. The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division

Considering my audience‚ arranging the sequence of my papers‚ and generating a productive thesis are a few of the many things that I have taken from English 111 and used to accomplish my goals in other classes this semester. Prior to taking English 111‚ I would literally throw any assignment together in the blink of an eye. The format and the structure of my papers did not even cross my mind. I have spent years trying to figure out the root cause in regards to why I always receive poor grades on my papers

to chromosome theory of heredity because they both deal with the genetic material coming from the mother and father of the organism. 10. Beadle and Tatum’s work opened up a whole new way of looking at genes and what they do as well as their functions and structural formation. Also their work helped to observe crossing between two sexes forming variability of offspring for genetic combinations and trait outcome. 11. The biochemical nature of a gene mutation is to add traits into a gene to

Success in English 111 “Success is a journey‚ not a destination. The doing is often more important than the outcome” I believe that a student will be successful in English 111 by arriving to class on time‚ by completing the mywritinglab assignments that are on blackboard‚ and reaching out for tutoring if needed. If a student arrives to class on time everyday they will not run the risk of being dropped from the course. However if a student does arrive late‚ or leaves early‚ the amount of class time
