Lab Questions: Lab #4 * Why are the chloroplasts traveling along the outer perimeter of the Elodea cell? The chloroplast are traveling along the outer perimeter to help move the vital nutrients thought the cells and convert them to substances used in the cell of the elodea cell. * What is the typical size difference between animal cells and bacterial cells? One of the main difference between an animal cell and a bacterial cell is a bacterial cell contains a plasmid‚ a ring of DNA‚ opposed

The Determination of the Effect of pH on Amylase Activity Grace Chung Abstract: Amylase is an important enzyme in the human body as it allows for the consumption of starch by breaking the polysaccharide down into maltose units. All enzymes‚ including amylase‚ function best at a certain optimal pH. Therefore‚ in this experiment‚ the effect of different pHs on the reaction rate of amylase is studied. It was hypothesized that the amylase-starch reaction would proceed fastest at a pH closest to

ACTIVITY 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. __The size and the concentration. ___ 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? __ The molecules were to large to go through. My results matched._ 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your

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

Courtney Cubine 6/19/13 June 20‚ 2013 Separation of a Mixture of Solids Purpose: The purpose of this experiment was to help the student learn how to separate a mixture of multiple different solids and determine the percentage of each component of the mixture. Procedure: I started off by removing the iron using the magnet‚ and then I weighed all of the iron I obtained from the mixture in a container I already knew the weight of and calculated the net weight of the iron.
