Anaerobic Respiration Lab Aim: To identify the products of anaerobic respiration in yeast Apparatus and Materials: boiling tubes‚ delivery tube‚ bungs‚ sugar‚ yeast‚ lime water‚ liquid paraffin‚ Bunsen burner Procedure: Water was first boiled in the boiling tube. A small amount of sugar was then dissolved into the boiled water‚ which was allowed to cool. A little bit of yeast was added then stirred. Apparatus was set up as shown in Figure 4. A layer of liquid paraffin was added to the surface

Make sure no air bubbles are clinging. Then take down final volume of water cylinder. 6. Dump the water out‚ then dry sample off. 7. Repeat this over with the other metal samples. * Hypothesis: * My hypothesis is that even though I will find the densities and names of the unknown metals its not going to be accurate because

Beet Lab By: Sumeet Grewal Purpose: The purpose of this lab was determining the effect of surface area on the beets ability to interact with the environment. Three similar sizes of beets were assigned. Each beat was cut up into different sizes as one large piece‚ two smaller pieces and eight tiny pieces. All three different slices of beets were placed in their own containers and tested. Observation: While the lab was going on‚ it was noticed the tiny pieces of beet were doing the best while the

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

There are multiple arguments that can be taken on to explain the differences in diffusion during this time period.

Although Christianity and Buddhism both flourished through social interaction over the silk roads‚ which lead to immense cultural exchange‚ there were various reasons linked to religious diffusion which were greatly taken advantage of with respect to regional and religious distinctions. Starting in 200 BCE and developing well into 700 CE‚ the silk roads and sea routes spanned across most of Asia‚ linking the Roman Empire with China and other

incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion is the movement of particles from an area of higher concentration to a lower concentration until they reach Equilibrium. (Hickman‚ 2008).Osmosis happens when water diffuses across the membrane from the region of lower solute concentration (higher

Unit 6 Assignment MT355-01 April 30th‚ 2013 Considering customer satisfaction as it applies to a university setting‚ what are some other areas in addition to those identified for the project that may contribute to students’ satisfaction/dissatisfaction with their education experience? The customer satisfaction survey seems to focus on academic resources only. It’s focusing on the classes‚ the advisors‚ the curriculum‚ and isn’t asking the students how they felt towards the school as a whole
