Lloyd Augustus Hall was born in Elgin, Illinois on June 20th, 1894. While growing up he was an honors student at West Side High School in Aurora, Illinois. He was captain of the school debate team while competing in baseball, football, and track. He graduated high school at the top 10 of his class. Hall then chose to attend Northwestern University. In 1916, he earned a Bachelor’s Degree in Pharmaceutical Chemistry. He then graduated, earning a degree from the University of Chicago. Through a…

Energy Flow and Nutrient Cycling in the Epipelagic Zone of the Ocean Introduction: “Energy Flow’’ is an environmental process that describes the flow of energy through a food chain and attempts to ascertain the relative importance of various individual component species and feeding relationships within a particular ecosystem. “Energy” itself is defined as the ability to do work: All living plants and animals expend energy in their environment. All three laws of thermodynamics apply,…

experiments that were performed. The presence of Nitrates and Phosphates were ruled out by the Solubility and Temperature Experiment as the concentration of these two pollutants did not exceed the maximum concentration in which fish are not affected. The presence of Nitrates and Phosphates were also ruled out by the Solubility of Gases Experiment as the the concentration of oxygen was never too low for the fish to survive, which would be an issue if Nitrates and Phosphates were in fact present…

the slit between the door and the ground. She smelt almonds, which is what nitrate smells like. That is how she knew that Andrew is keeping high flammable films in his storage space. Ceinwen wanted to confront Andrew Evans and ask him directly whether he had Mysteries of Udolpho or not. Matthew told her to be rational and think this through. He suggests that they write a letter to the manager and inform them of the nitrate in the storage space that could potentially set the building on fire. …

In the lab, the results concluded that the water is indeed not healthy to drink for humans. The tubes indicated that there presence of fecal pathogens; which there was more than one. If one was presence, the water makes it automatically not healthy to drink. The different factors that were measured was the dissolved oxygen in which is an important factor to the aquatic ecosystems where all aquatic animals need to survive. Natural waters are healthy, stable in a environment, and have the chance…

There are many factors that contribute to the conclusion that the steelhead trout will and will not be able to reestablish themselves in the Arroyo Del Valle presently. Some of the most important factors for the re-establishment of the trout are the relatively stable pH, adequate DO levels, and low pollution. From our graphs, it is evident that the pH of the creek is consistent around 7, which is a pH that the steelhead can establish themselves and live in. Steelhead trout require a DO level…

ammonia in the riffle, pool, and midstream areas as well as the dissolved O2 levels. Our team started off by splitting into two teams; a group of two and a group of three. The team i was on, the small group of two, worked on testing the phosphate and nitrate in the riffle, pool, and midstream samples. Starting off with phosphate, we grabbed the phosphate chemistry kit and got to work following the directions in order to accurately test out the amount of phosphate in each sample. We used two of…

IONIC LIQUIDS Introduction:- Ionic liquids are actually salts that are liquid in state, normally referred to compounds that have melting point below an arbitrary temperature i.e. 100° C. Unlike some other ordinary liquids like water and gasoline, that are composed of neutral species while ionic liquids are composed of ionic species and ionic intermediates commonly known as “ionic fluids” and “liquid electrolytes”. In ionic liquids there is a species that has a delocalized species and the other…

Identifying a bacteria based off of physical characteristics is almost impossible due to the commonality of shapes and physical features. Because of this, a wide range of biochemical tests were preformed in order to better identify the bacteria. Being able to identify an unknown was the most interesting part of the microbiology lab this semester, as well as, being able to preform the various tests. Proper aseptic technique was used throughout the semester and followed during all biochemical…

Biology Field Study Draft Part A Bulimba Creek is a perennial stream located in the eastern and south-eastern areas of Brisbane (Committee, 2016). The creek covers an area of 122 square kilometres and runs through 20 of Brisbane’s southern and eastern suburbs as it makes its way towards the Brisbane River (Committee, 2016). As a result of the creek covering such a large area, Bulimba Creek is a very important part of Brisbane’s ecosystem and society. Although Bulimba Creek is a part of…
