Boiling

The purpose of the liver lab was to understand how enzymes, more specifically catalase, break down poisonous chemicals, hydrogen peroxide. In the lab we used multiple reactants, temperatures, and pH levels. For the tissues and enzymes we used livers, new, used, cold, warm and boiled, chicken breasts, potatoes, and apples. We also used hydrogen peroxide, warm and cold, acidic and basic, and used liquid from a reaction. Hydrogen peroxide acts as a substrate for the enzymes. The reactants were the…

Barber-Surgeon I have always been intrigued with the study of medicine. I started school in 2014 with the goal to graduate with a BSN. At the beginning of the semester it was mentioned in class that people in the early 1200 to 1820 there was a Barber-Surgeon. A Barber-Surgeon is a barber that cuts hair, shaves people, pulls teeth, removes superficial tumours, stops haemorrhaging, drains pus filled sores, preforms enemas, used leeches to help with blood clotting, curetted fistulas, and sutured…

What is Sodium cyanide? Sodium Cyanide is an inorganic Compound, it has a formula NaCN. Cyanide actually has a high affinity for metals which can lead to a high toxicity of the salt. Sodium Cyanide has a boiling point of 2,725°F (1,496°C) and it also has a melting point of 1,047°F (563.7°C). A common name for sodium Cyanide is sodium salt of hydrocyanic acid. Cyanide has an appearance of while crystalline or granular powder. This toxin releases a hydrogen cyanide gas which is…

Chromium Chromium was discovered in France in 1797. A man named Louis-Nicholas Vauquelin discovered chromium while experimenting with a material known as Siberian red lead. The name Chromium comes from the Greek word "chroma" meaning "color." Chromium got this name because of the many different colors in the element. This element is hard, metallic and shiny. Chromium doesn't tarnish. Chromium is a metal element. Chromium's symbol is "Cr" and has an atomic number of 24. This metal is the…

I believe that Edwin L. Godwin is foreshadowing in his essay, “The Eclipse of Liberalism,” of the many of conflicts that will occur in the first half of the twentieth century when he warns about the danger of nationalism once liberalism fades away. Godwin originally wrote the essay in 1900. Within the essay, he argues that liberalism rose as a consequence of the corruption and abuse suffered under monarchies. Towards the end, Godwin mentions how nationalism is now dominating over liberalism,…

Why Testing on Prisoners is a Bad Idea Despite all the backings on social media from people around America, it probably isn't a great idea to test on Prisoners for a ton of legal reasons. After discovering that the prisoners of the concentration camps had been tested on, a set of 10 ethical principles were placed in effect called the Nuremberg code. This code eliminates all human experimentation unless the person is willing and also does not permit such testing on willing humans until results…

which improved its protein and vitamin content. Due to the high level of vitamin B, people began to replace meat with beer, ultimately leading to the switch from hunting to farming. Beer was also much safer to drink then water because it was made in boiling water. Because of beer and farming, there was a surplus of food, which helped with the control of food shortages. Surplus food became important religiously because it was seen as an offering to the gods. Contributions of food were recorded…

A Day in the Brittenden Bach Le Bons Bay, an isolated beach location two hours away from Christchurch, The Brittenden Family owning a 1970’s style bach with shag carpet and no cell phone reception or Internet, Three rooms and a 3 litre hot water tank for 12 people the tank also happens to shower in after a swim in the beach or the estuary. The Hot water was already a problem but it was becoming more serious as my sister and step-sister hair grew longer as they would have to spend more time…

and RNA are found in the nuclei of all cells and their job is to transmit the information needed for cellular growth and reproduction (Averill & Eldredge, 2007). 2. The number of carbons and the branching determines the boiling point, where the higher of either increases the boiling point. The reason behind this is hydrogen bonding (Clark, 2003). In ethanol there is an -OH group present. The oxygen pulls…

Dakota Lynn Martin September 30, 2016 What’s in the Cup? Coffee! The industrial revolution was the time period of up-and-becoming industries. New technology was being created, and old technology was advancing at a rapid rate. One specific industry that was heard of, but not popular in America at the time, was the coffee industry. Coffee first came to America during the Boston Tea Party in 1773, and since then, it has become a worldwide commodity. Today, people’s knowledge about coffee is…
