Electrical Components and Circuits Course: PHY101 Purpose: The purpose and objectives of this lab was to be able to draw completed electrical circuits using the correct symbols for selected electrical components‚ including batteries and diodes. Another focus was to calculate the proper resistance using Ohm’s law‚ use proper electrical currents and quantities‚ and lastly measure voltage and resistance in an electrical circuit using a multimeter. Materials:

Part I: Pre-Lab Diffusion/Osmosis Pre-Lab Introduction: Dialysis tubing allows molecules to diffuse through microscopic pores in the tubing. Molecules that are smaller than the pores can diffuse through the dialysis membrane along the concentration gradients. Molecules that are larger than the pore size are prevented from crossing the dialysis membrane. Answer questions in complete sentences. For problems‚ show equations and work with units and appropriate significant figures. Part IA: In the following

Inheritance and Polymorphism This is what makes OO interesting. Inheritance is useful when there is a common set of characteristics for many different classes. This “base set” becomes the superclass‚ or base class. Other classes can inherit this basic set and also add their own unique methods and fields. Such classes are called subclasses

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment

completely different than the aforementioned - something that caters more to their interests. So what can we do for these bored teenagers? You see‚ we have all the facilities etc. From bars to reacreational areas‚ places offering live music‚ a countless amount of shopping malls. Yet‚ teenagers are still bored. Thus I think it is crucial to ask the young people would like to do‚ then officials can plan their activities and build the venues accordingly. If we don’t‚ we will face the risk of continually

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

concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a semipermeable membrane (permeable to the solvent‚ but not the solute) separating two solutions of different concentrations. Osmosis can be made to do work. The osmotic pressure is defined to be the minimum pressure required to maintain an equilibrium‚ with no nett movement of solvent. Osmotic pressure is a colligative property‚ meaning that the osmotic pressure depends on the molar
