Cell Biology Lab - Homework 1 Due to the week of Oct. 6-10th This is NOT a lab group project. Do the work individually. You may use any source other than your fellow students. Show your work‚ use your own words and cite all references. 1. (20 points) The HeLa S3 cancer cell line is considered to be “continuous” due to acquired mutations that enable the cells to evade senescence. This property is one of several hallmark characteristics of cancer cell lines. Describe three hallmark characteristics

Observations: When Malaria is present and infects red blood cells‚ parasites can infect cells carrying defective hemoglobin which may result in death. Allele frequency changes over time depending on the pressures or circumstances facing a particular population. African populations are especially impacted by both malaria and sickle cell anemia. Depending on the impacted population‚ allele frequency often shifts and well suited organisms are likely to survive and allele frequencies can increase

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

01) The Cell Structure and function Abstract In this lab the structures of various cells were viewed through a compound microscope. The bacteria in yogurt was viewed a long with a slice of potato‚ and a thin skin of red onion. The potato was dyed with iodine while the red onion was dyed with methane blue. The students had to assemble the first three slides. Two more slides were provided these are the yeast and protozoa cells. Those two are also viewed

The aim of this lab session is to demonstrate the effect of different conditions on membrane permeability. 4.2 Learning Objectives In this Lab Session‚ students will acquire the skills to: - analyze the effect of different temperatures on membrane integrity. - analyze the effect of the organic solvent acetone on membrane integrity. 4.3 Introduction Even though membranes separate cells from their surrounding environment and different organelles within the cells from the cytoplasm

investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot using a cork borer

Hand Washing Experiment Outline I. Introduction a. This lab was conducted in order to understand and apply the scientific method. The experiment tested the effectiveness of reducing microorganism (bacteria) with the use of various hand soaps. b. Hypothesis: If the Harris Teeter Foaming Hand Soap is more effective in reducing bacterial growth than the Soft Soap hand soap‚ then there will be less bacterial/microorganism growth present on the agar plate for the Harris Teeter Foaming
