Lab Report 1: Subculturing Adherent Cells Fibronectin‚ integrin alpha 3‚ and actin are all involved in cellular adhesion at both the cellular and molecular levels. Integrins are the primary trans-membrane receptors that mediate dynamic interactions between the extracellular matrix and the actin cytoskeleton whenever a cell is motile. Integrins bind to the extracellular matrix and link to the actin cytoskeleton via a shirt cytoplasmic tail; they also help determine cellular binding specificity because

The Effect of Different Types of Insulation on Heat Retention Aim I am going to investigate the effect of different types of material on heat retention. "Which of the four materials‚ cotton‚ foam‚ aluminium foil and bubble wrap‚ is the best insulator?" Hypothesis The four materials tested in this experiment are cotton‚ foam‚ aluminium foil‚ and bubble wrap. Materials that are good insulators will absorb heat slowly and therefore the water inside the cup will stay warm for

TITLE AND AUTHOR Lab 7 Analysis of purified Concanavalin A via:Hemagglutination INTRODUCTION The purpose of this lab was to test the biological activity of ConA by performing a hemagglutination assay. If ConA is active then agglutination will occur due to ConA’s free receptors being able to bind to the glucose residues on the sheep’s red blood cells. If ConA is not active then no agglutination will occur. To test the hemagglutination reaction‚ two types of ConA solutions

1. The woman in the photograph is Henrietta Lacks. She had seen the picture many times in magazines and science textbooks‚ on blogs and laboratory walls. Rebecca Skloot may start to write this book to know about Henrietta Lacks. She was staring at the photo for a long time and she always had wondered about Henrietta Lacks’ life story. Rebecca Skloot went to an alternative school after she had failed her freshman year at a regular public high school. She took a biology class at a community college

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining

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

Aim To investigate in the amount of antioxidants present in the two given tea samples for four consecutive brews each. Introduction Hypothesis: The amount of antioxidants would decrease as the number of brews increases. Biological principal: An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons. Oxidation reactions can produce free radicals. These radicals can start chain reactions. When the chain reaction occurs

Jan Levi O. Pangilinan Mr. Jestoni Basco BSIS – IIIB BIOS(Basic Input/Output System) 1. What is BOIS? The term BIOS (Basic Input/Output System) was invented by Gary Kildall and first appeared in the CP/M operating system in 1975‚ describing the machine-specific part of CP/M loaded during boot time that interfaces directly with the hardware (a CP/M machine usually has only a simple boot loader in its ROM). Later versions of CP/M (as well as Concurrent CP/M‚ Concurrent

Cell Surface Glycoprotein Receptor Analysis Using Concanavalin A Purpose: During this 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
