QUESTION 1 1. Bacteria is stained using a primary stain called crystal violet and then fixed with a mordant which in most cases is iodine. While some bacteria have the ability to retain the primary stain, others discolor when exposed to the acetone and alcohol (95%). Hence, the Gram stain divides bacteria into two groups- these bacteria are grouped according to their differential staining properties. One group is Gram positive bacteria and the other group is Gram negative bacteria. The Gram…

Laboratory Diagnosis Monitoring Parameters • Tourniquet Test Acts as an emergency diagnostic tool whereby formation of more than 20 petechiae per square inch indicates a positive tourniquet test. A circle of 2.5 cm in diameter may be drawn and the number of petechiae in it is counted. More than five petechiae indicates positive test. • Complete Blood Cell Count Blood tests present with lowered total white blood cell, platelet and neutrophil counts and a 20% or more increase in haematocrit…

Amino acids Amino acids are building block s of proteins. Each amino acid contains main three structural components. 1) Amino group 2) Carboxcilic group 3) R group Figure 1 https://www.bing.com/images/search?q=amino+acids&view=detailv2&&id=072990A13D7C6B29926E0FC3F9E9BE59C8A6322E 2016 R can be hydrogen or any other functional group .in world there are around 182-200 found to be present in nature but we can find 20 aminoacids in…

According to the ATI PowerPoint, “The pancreas and the liver are the main function supporters of insulin. The endocrine portion of the pancreas has about 1 million small glands and the islets of Langerhans, scattered through the organ” (ATI PowerPoint). There are two types of cells that are important to glucose controls, alpha and beta cells. The alpha cells produce glucagon, a hormone that causes the release of glucose from the cell storage sites whenever blood sugar levels are low. The Beta…

Throughout the nineteenth century moral reformers and prohibitionists worked tediously for the Prohibition of alcohol. At the time, many people believed that alcohol was responsible for all things wrong with society and the people in it. For example, alcohol was blamed for poverty, disease, insanity, degeneracy, and crime. American citizens thought that Prohibition would alleviate the destructive effects of alcohol and transform society and its citizens into law-abiding, pure, healthy, honest…

Volatile liquids require a small amount of thermal energy to vaporize due to the fact that many contain nonpolar molecules. This property of volatile liquids was utilized in this experiment to determine the molar masses of unknown volatile liquids by employing the ideal gas law in the course of vaporization and condensation of the liquids. This was done by taking measurements of volume, temperature, mass, and pressure throughout various steps of the experiement. These findings were then applied…

safety analysis, explain how 3D printing could be the cause of possible “adverse health effects” (par. 5) because of some of the chemicals released in the 3D printing process. In a controlled laboratory setting, there were traces of toxic chemicals “acetone, n-butane, 2-butanone, 1,4-dioxane, ethanol, isopropyl, alcohol (2-propanol) and toluene, (par. 16) which can have negative effects on the body if inhaled. This study is one of the first to be conducted relating 3D printing to air quality and…

Everyone knows at least one person who smokes cigarettes. If not, then everyone has inhaled the foul odor of the toxic smoke leaving the addicts body. With nearly 42.1 million people in the United States smoking cigarettes, this addiction has become a problem to say the least. “For decades, the public health community in the United States has asserted that cigarette smoking is the most deadly epidemic of modern times” (Verheij 1). According to the National Institute of Drug Abuse, every one in…

Lignocellulosic-based biomass Unlike starch, lignocellulosic biomass is a plant-based material composed of lignin, cellulose, and hemicellulose. This class of biomass includes wood and fibrous materials from organic sources, agricultural wastes, organic municipal wastes, and organic industrial wastes [18]. Agricultural wastes contribute as the major lignocellulosic resources investigated for biofuel production. Among them are oil palm biomass [19,20], corn stalk [21], rice straw [22], wheat…

In recent years, modern Li-ion batteries (LIBs) have become ubiquitous power source for a variety of applications such as laptops, mobile phone, and digital camera to electric vehicles, owing to their high power density, high energy density, and long cycle life.1–3 However, there are still many critical challenge to increasing the energy, power density, and improved cycling stability.4–6 In particular, selecting noble electrode materials is the hottest topics in the LIB field. Among them, bulk…
