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

Conflict can reveal unexpected qualities in an individual. Philosopher Emerson once said “every coin has two sides; so do conflicts”. In the pages of human history‚ conflicts are unavoidable and while major conflicts such as war have been evil forces in the world it can also produce very positive results. That is not to say conflict is entirely positive. When conflict arises there are those individuals that show unexpected qualities; those assets that are sudden and unforseen. These assets can be seen

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

He asks you to help him figure out what is inside. There is one catch: He does not want to open the can‚ just in case there is something expensive inside.

appropriate methods to answer questions and solve problems about monohybrid inheritance. Questions Q1 Some forms of albinism‚ a genetic disorder‚ may be due to a single gene mutation. The allele for albinism is recessive to the allele for no albinism. A woman is heterozygous for albinism. Her male partner is homozygous for the ‘normal’ allele. a Does the woman suffer from the condition? no b What percentage of their children are likely to be carriers? 1:4 c Explain what is meant by the term

orientation; is it a genetic inheritance? The reason why I chose this as my topic‚ is involved with my personal life. Most of my family is anything but heterosexual: My mom‚ my brothers‚ my sister and myself. In that case‚ I was genuinely interested in knowing whether sexual orientation has anything to do with genetics. Sexual orientation is an important thing to some peoples lives‚ so understanding it is very important. There is so much involved around ‘sexual orientation’ that it can be overwhelming sometimes

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

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
