Introduction: This lab helps further our understanding of essential principles behind diffusion and osmosis. Permeability‚ concentration gradients‚ plasmolysis‚ water potential‚ and equilibrium were also concepts that were delved into in this lab. Understanding how diffusion and osmosis works is essential to understanding biology. Each time a cell has something move into or out of it‚ some sort of principle studied in this lab is occurring. Diffusion‚ osmosis‚ and passive and active transport are

Question 1: The sequence in the entry that was obtained from sequencing a piece of DNA from Vibrio fischeri genomic DNA digested with Sal I is 8654 bp long. Question 2: The -10 sequence for the lux operon is tgttata. 2 nucleotides are different when compared to the ideal sequence. Question 3: The lux R has its own promoter and is transcribed in the opposite direction from the lux operon‚ so it cannot be transcribed from the same strand because the RNA Polymerase recognizes promoter sequences

The hypothesis for this lab was that Core B will be the least flexible due to a loss in water. Unfortunately‚ my results led my hypothesis to be incorrect. The results that were received was that Core C was the most flexible‚ Core B was somewhat flexible‚ and Core A was not flexible and stiff. Core A was the most non-adjustable due to it being hypertonic which means that the total concentration of all the dissolved solute particles is greater than the other solution. Core B was isotonic meaning

1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The environmental factors that you are testing on the rate of transpiration are the independent variable of this experiment. These independent variables are specifically light‚ fan‚ dark‚ and humidity. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants are things like the type of plant used‚ room

experiment we compared the hemagglutination reaction of control Con A solution at 2 mg/ml in Con A buffer with the hemagglutination reaction of your own purified Con A sample that you diluted previously at 2 mg/ml in Con A buffer. The purpose of this lab was to determine the strength of the reaction by performing serial dilutions on both the Con A sample and the control Con A sample‚ and determine through observations whether or not addition of galactose or mannose will inhibit this reaction. I hypothesize

Effect of Enzyme and Substrate Concentration on Reaction Rate by Zachary A. Poché Biology 155 Laboratory October 15‚ 2014 Lab Partners: Cade White‚ Hannah Ragas‚ Russheka Aremillion ABSTRACT In order to increase the reaction rate‚ substrates attach to the active site of enzymes which decrease the activation energy required to convert substrates to products. We examined the effect of enzyme concentration and substrate concentration on the overall rate of the reaction. To determine

DESIGN: Research Question What effect does varying the alcohol concentration of yeast have on its fermentation? Introduction Fermentation is the stage during which most CO2 is produced. When no oxygen is available‚ yeast will switch to an alternate metabolic pathway utilizing sugars for energy and producing‚ primarily‚ CO2 and ethanol. Yeast divides rapidly in this phase‚ reaching its carrying capacity (about 50 million cells/ml) in the wort‚ or must‚ and remains suspended
