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

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

balloon Bar Graph: Discussion Questions: 9) My prediction had been that the test tube with 10% of sucrose inside of it would make the most amount of carbon dioxide. My hypothesis was correct‚ and the size was gradually increasing throughout the lab. At the end it was the biggest‚ so after 1440 minutes‚ the 10% test tube was the only solution that had visible bubbles of carbon dioxide. After 1440 minutes there were no carbon

Plant Pigments and Photosynthesis Problem: We are going to separate and identify pigments and other molecules from cell extracts through a process called chromatography. We will also test the theory that light and chloroplasts are required for light reactions to occur. Background: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This is what makes them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than

CARDIOVASCULAR SYSTEM The Cardiovascular system consists of the cardio -heart and the vessels that carry blood to all parts of the body. If this system does not work properly then oxygen‚ hormones‚ water‚ nutrients and wastes won’t reach their target destinations. 5 liters of blood in body.

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

Sample Free Response Questions 1. The framers created a bicameral legislature because of the Great Compromise at the Constitutional Convention which stated that one house’s representation will be based on a state’s population and the other would have equal representation. Another reason is that it would help prevent tyranny because both houses can “check” each other to make sure one does not get to powerful. One power unique to the House of Representatives is that revenue bills must originate from

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
