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

region of higher solute concentration‚ in order to equalize the solute concentrations on the two sides. We didn ’t know anything about osmosis except that it was a word in the dictionary that we never picked up. Osmosis and diffusion are similar because osmosis is the result of diffusion across a semi-permeable membrane. If two solutions of different concentration are separated by a semi-permeable membrane‚ then the solvent will most likely to diffuse across the membrane from the less concentrated to the

xxxxxx Ms. xxxx Biology 20 November 2013 Osmosis Lab Problem: What’s the order of the concentration for each solution and how does it affect the movement of water? Hypothesis: Experimenter thinks the order of the solutions according to their concentration is D‚A‚E‚C‚B‚ from smallest. And the water will pass through semipermeable tubing bag from low to high concentration to thin the concentration inside the bag. Osmosis is a diffusion of water particles and is one of the passive transport

native religion‚ allowing it to be accepted in society and spread through monasteries and schools. However‚ they both did become incredibly popular and proliferate. There are multiple arguments that can be taken on to explain the differences in diffusion during this time period. Politically‚ Christianity posed a greater threat to the Jews than the Buddhists to the Hindus. Economics also played a role; Buddhism had the silk roads to travel and spread through. Religiously‚ Christianity and Buddhism

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

genuinely understand the lab and make a plausible prognostication one must first grasp the concepts of the cell membrane as a semi-permeable barrier and the kineticism of dihydrogen monoxide. Cell membranes are semipermeable‚ denoting the membrane is a barrier to most‚ but not all molecules. Semi-permeability dissevered and bulwarks

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

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

TRANSPIRATION DESIGN LAB Transpiration is the process through which water is lost from a plant. Water is taken into a plant through roots and root hairs by osmosis‚ and it exits the plant through stomata. Transpiration helps the diffusion of both O2 and CO2 plus it helps the movement of water throughout the plant. There are some factors that affect the rate of transpiration of the plant. Those factors are mainly humidity‚ soil water supply‚ sunlight‚ temperature and wind. Any alteration

Dissection lab In the past 3 weeks we have been dissecting animals of all different sorts. We dissected a worm‚ crayfish‚ grasshopper‚ and a perch (fish). In my conclusion I will explain the diet‚ habitat‚ and how these relate to the structure of these animals. First I am going to be talking about the worm. The Earthworms have setae in groups around or under their body. The setae‚ paired in groups on each segment‚ can be moved in and out to grip the ground or the walls of a burrow. Worms travel
