INTRODUCTION When it comes to Biology, one of the most well known, and interesting topics within the science is DNA and genetics. Although DNA is typically used in agarose gel electrophoresis, it was not provided for this lab, so the use of three different dyes had to make do. A null hypothesis was created indicating that dyes with a lighter molecular weight would not pass through the agarose gel easier than those with a heavier molecular weight. Where as the alternate hypothesis stated that,…

Microbes of the infected root canal system Historically, the most wide-spread method for detecting and characterizing bacteria has been by culturing. Culturing bacteria allows the analysis of their morphology, virulence, gram-staining pattern, the quantization of viable microorganisms, as well as the testing of their susceptibility to antibiotics. Consequently, this method may not allow normally viable bacteria to cultivate as the selected culturing media may not have the nutritional and…

From news broadcasts, food labels and restaurants, to your own backyard, the organic craze is spreading across the country. With increasing members of society demanding “organic”, it may be time to offer a program specifically for this growing trend. A majority of you already return clippings, use IPM techniques, fertilize with slow release nitrogen, spot treat and minimize pesticide/herbicide applications, which all describe a successful sustainable lawn care program. By offering programs that…

The Transfer of the pGLO plasmid into Escherichia coli from the DNA of Aequorea victoria Introduction The goal of this lab is to be able to take the gene responsible for allowing organisms to glow in the dark, called Green Fluorescent Protein (GFP), located in the pGLO plasmid, and move it from the DNA of the Aequorea victoria to bacteria, Escherichia coli. The pGLO plasmid is found naturally in some organisms such as the A. victoria,…

The purpose of Activity 1 of this lab is to understand how cell transportation works, The purpose of the second part is to explore semipermeable membranes. The purpose of Activity 3 is to explore how the size of a cell affects cell transportation. Background All cells are surrounded by a barrier called the cell membrane. It regulates what enters and leaves the cell, and also protects and supports the cell. Cell membranes are semipermeable, meaning it doesn’t allow all molecules to pass through…

Immune System(Remove) What does immune system means? The immune system is the one of necessity system in the body. It helps the body defend against every foreign body that causes disease for body. The immune system is getting stronger and stronger while it destroys disease. It takes experience from disease which it is destroyed. The immune system is defined as “the system that protects your body from diseases and infections” in Merriam-Webster dictionary. In other words, the immune system…

sugar content of food sample by performing Fehling method and to identify invert sugar content of sugars by using polarimetry and also to learn property of invert and reducing sugar. Carbohydrases represent a large class of enzymes hydrolyzing polysaccharides and low-molecular-weight glycosides. They belong to the class of hydrolases. Carbohydrases are classified according to their specificity…

PURPOSE We used chemical indicators to identify possible sugar, starch, protein, and lipids present within two common food items as well as the dead Anna Garcia’s stomach contents. HYPOTHESIS If Anna ate foods like pizza, ice cream, and Oreo cookies like she said on her food log, then her stomach contents should react with the chemical indicators for glucose, maybe starch due to the pizza. INTRODUCTION The experiment considers the types of macromolecules within each piece of food. Each type…

I.) Introduction The worst feeling for a parent is seeing their child in pain. I discovered this when I was having dinner with a family friend, Ryan, and he told me about when his daughter, Brooke, had a severe allergic reaction to shrimp. He told me about how his family was having a Fourth of July barbecue one year and everything seemed normal. Brooke had just gotten a plate of food, on which was a shrimp kabob. She started eating and after a minute or two, she started wheezing. The…

Over the last decade, monumental advances in the medical field have taken place, resulting in prompt recognition and management of many diseases. Despite this, meningococcal disease remains one of the leading causes of death in children and young people worldwide (Dowson, 2014). With its rapid onset and serious nature, meningococcal septicaemia affects up to 0.95% of the western world’s population each year making it essential for health professionals to understand the pathophysiology,…
