A condenser: during distillation the vapour passes through a tube that is cooled by water
Fractional distillation: The process used to separate a mixture of several liquids, based on their different boiling points
Aerobic respiration: chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also known as oxidative metabolism, cell respiration, or aerobic metabolism
Anaerobic reparation: form of respiration in which energy is released from chemical reactions in which free oxygen takes no part
Equation for combustion of an alcohol: R-OH (l) + O2 (g) --> CO2 (g) + H2O (l)
Fermentation: In its strictest sense fermentation (scientifically called zymosis) is the energy-yielding anaerobic metabolic breakdown of a nutrient molecule, such as glucose, without net oxidation. Fermentation yields lactate, acetic acid, ethanol, or some other simple product.
Cell membrane: The outer boundary of the cell. The cell membrane helps control what substances enter or exit the cell
Endoplasmic reticulum: network of membranous tubules in the cytoplasm of a cell; involved in the production of phospholipids, proteins, and other functions. Rough ER is studded with ribosomes; smooth ER is not.
Golgi apparatus: An organelle in eukaryotic cells containing cells consisting of stacks of membranes that modify, store, and route products of the endoplasmic reticulum
Ribosomes: Small cellular components composed of specialized ribosomal RNA and protein; site of protein synthesis. See ribonucleic acid
Centriole: Paired cellular organelle which functions in the organization of the mitotic spindle during cell division in eukaryotes
Mitochondria: The mitochondria are the principal energy source of the cell. Mitochondria convert nutrients into energy as well as doing many other specialized tasks
Cytoplasm: the cellular substance outside the nucleus in which the cell's organelles are suspended
Nucleus: the nucleus is an organelle, found in most eukaryotic cells, which contains most of the cell's genetic material. Nuclei have two primary functions: to control chemical reactions within the cytoplasm and to store information needed for cellular division
Vacuoles: A membrane-enclosed sac taking up most of the interior of a mature plant cell and containing a variety of substances important in plant reproduction, growth, and development
Chloroplasts: Disk-like organelles with a double membrane found in eukaryotic plant cells; contain thylakoids and are the site of photosynthesis. ATP is generated during photosynthesis by chemiosmosis.
Cell wall Structure produced by some cells outside their cell membrane; variously composed of chitin, peptidoglycan, or cellulose.
Organelle: specialized subcellular structure having a special function; eg mitochondria.
23/46 chromosomes: Egg and sperm cells contain 23 chromosomes, made up of 22 autosomes and either an X or a Y.
James Kittelson’s biography on the life of Luther is thought provoking and informative. Kittelson does not have a concise thesis, but as it is a biography the central theme of Luther the Reformer is an insightful narrative of Martin Luther’s life from his birth in Eisleben until his death on February 18, 1546 in Eisleben. Kittelson thoroughly and with great detail and sources explains Luther’s mission to reform the catholic church. Luther the Reformer seeks to condense Luther’s life in a manner which is more easily read for those who do not know the reformer’s story well. Luther is portrayed not only as a theologian throughout the book, but as a person with struggles and connections throughout the Germanic region in which he lived. Luther’s theology is portrayed throughout the entirety of the book, and Kittelson approaches Luther’s theology by explaining Luther’s past. The inclusion of
The Coast Guard, for instance, rescued some 34,000 people in New Orleans alone, and many ordinary citizens commandeered boats, offered food and shelter, and did whatever else they could to help their neighbors. Yet the government–particularly the federal government–seemed unprepared for the disaster. The Federal Emergency Management Agency (FEMA) took days to establish operations in New Orleans, and even then did not seem to have a sound plan of action. Officials, even including President George W. Bush, seemed unaware of just how bad things were in New Orleans and elsewhere: how many people were stranded or missing; how many homes and businesses had been damaged; how much food, water and aid was needed. Katrina had left in her wake what one reporter called a “total disaster zone” where people were “getting absolutely

All living organisms require energy. In order to obtain energy, cells within the organisms must go through the processes of cellular respiration and/or fermentation. The way in which “oxidation of glucose leads to ATP production” is emphasized in cellular respiration (Freeman et al., 2014).
Cellular respiration – “is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products” (definition)

There were many things destroyed and many people displaced from their homes and family. Studies show more than 400,000 people in the New Orleans and Mississippi Gulf area were forced to travel away from everything they knew (Katrina Displaced 400,000, Study Says). The emotional damage of the storm is not something easily communicated but the financial toll calculated is somewhere around $96-$125 billion, the insurance losses were looked at at around half that (Hurricane Katrina Damage Facts and Economic Effects). With so many people not where they should be and facing the financial hardships of the storm’s aftermath, the economy suffered. As well as the oil and gas pipelines damaged in the storm and unattainable through the debris. All these costs affected production, sales, and caused the Gross Domestic Product and economic growth to change from 3.8% to 1.3% by the October-December quarter. Total estimated costs to property was es...
Even though it is the responsibility of the federal and state governments to aid citizens during times of disaster, the people devastated by Hurricane Katrina were not effectively facilitated as according to their rights as citizens of the United States. The government’s failures to deliver assistance to citizens stem from inadequate protection systems in place before the storm even struck. The Federal Emergency Management Agency and the Department of Homeland Security were the two largest incumbents in the wake of the storm. The failure of these agencies rests on the shoulders of those chosen to head the agency. These directors, appointed by then president George W. Bush, were not capable of leading large government agencies through a crisis, let alone a disaster the magnitude of Hurricane Katrina. Along with the federal government, the state of Louisiana and the city of New Orleans did not do enough to lesseb the damage caused by the storm, and forced thousands of poorer citizens to remain in cramped and unsanitary conditions for extended periods of time. The culmination of federal, state, and local government’s failures in suppressing and repairing the damage of Hurricane Katrina to a level acceptable for citizens of the United States is a denial of the rights citizens of the United States hold.
Chronic obstructive pulmonary disease (COPD) is preventable disease that has a detrimental effects on both the airway and lung parenchyma (Nazir & Erbland, 2009). COPD categorises emphysema and chronic bronchitis, both of which are characterised by a reduced maximum expiratory flow and slow but forced emptying of the lungs (Jeffery 1998). The disease has the one of the highest number of fatalities in the developed world due to the ever increasing amount of tobacco smokers and is associated with significant morbidity and mortality (Marx, Hockberger & Walls, 2014). Signs and symptoms that indicate the presence of the disease include a productive cough, wheezing, dyspnoea and predisposing risk factors (Edelman et al., 1992). The diagnosis of COPD is predominantly based on the results of a lung function assessment (Larsson, 2007). Chronic bronchitis is differentiated from emphysema by it's presentation of a productive cough present for a minimum of three months in two consecutive years that cannot be attributed to other pulmonary or cardiac causes (Marx, Hockberger & Walls, 2014) (Viegi et al., 2007). Whereas emphysema is defined pathologically as as the irreversible destruction without obvious fibrosis of the lung alveoli (Marx, Hockberger & Walls, 2014) (Veigi et al., 2007).It is common for emphysema and chronic bronchitis to be diagnosed concurrently owing to the similarities between the diseases (Marx, Hockberger & Walls, 2014).
In the most general terms, the nucleus is the command center of a eukaryotic cell. Although the origin of the organelle is unclear, it is believed that it is derived from a symbiosis relationship between a bacterium and an archaea (Martin W. 2005). Being the main hub for the inner workings of a cell involves different functions overall. These nucleic functions are determined by the genes within the DNA of the cell. Functions of the cell are also regulate by soluble proteins that come in and out of the cell via the membranes and specific channels or the nuclear pore complexes. The overall objectives of the nucleus include; gene expression, compartmentalization, and processing pre-mRNA. The functions of the organelles and sub-regions

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function, all cells have a surrounding membrane and an internal, water-rich substance called the cytoplasm, the composition of which differs significantly from the external environment of the cell. Within the cell is genetic material, deoxyribonucleic acid (DNA), containing coded instructions for the behavior and reproduction of the cell and also the chemical machinery for the translation of these instructions into the manufacture of proteins. Viruses are not considered cells because they lack this translation machinery; they must parasitize cells in order to translate their own genetic code and reproduce themselves.
The nucleus contains genetic material that controls all the activities within a cell. A nucleus is made up of D...
