University of Phoenix Material Appendix B – Identifying Bacteria Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium‚ biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION

than 5000 mL/day continued until the 16th postoperative day. Plasma antidiuretic hormone (ADH) levels were within the normal range. Plasma human atrial natriuretic peptide (hANP) and brain natriuretic peptide (BNP) were elevated postoperatively‚ and the elevation of these peptides was one possible cause for the severe polyuria. Because ADH levels in the tumor fluid were not elevated‚ the tumor was not an ADH-secreting tumor. Urinary b2-microglobulin was significantly elevated after the operation‚ thus

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination

I. Kidney Anatomy A. Every day the kidneys filter nearly 200 liters of fluid from the bloodstream‚ allowing toxins‚ metabolic wastes‚ and excess ions to leave the body in urine while returning needed substances to the blood; of this‚ only 1-2 L of urine is actually formed daily B. Location and External Anatomy 1. Kidneys - bean-shaped organs that lie retroperitoneal in the superior lumbar region. 2. The medial surface is concave and has a renal

Homeostasis maintains the body’s internal environment it allows organs and cells to function at their best. It keeps the body at steady state‚ this refers to the fact that conditions need to remain constant‚ if not then normal function would be disrupted. However there is a certain limit set ‚ this is due to the changing values ‚ rather they are maintained around an ideal value which is also known as the set point. The skin regulates most of the body temperature and uses a mechanism called negative

Adkins or Fadkins Case Study Part One – 1. Proteins - Proteins are chains of amino acids. In general‚ proteins may be structural proteins used to build tissues‚ they may be enzymes that mediate chemical reactions‚ or they may be hormones. Examples of proteins would be channel proteins in cell membranes‚ collagen protein in the skin‚ actin and myosin in the muscles‚ and hemoglobin in red blood cells. Types of dietary sources would be‚ meat‚ milk‚ (both of which are not pure proteins‚ but are

Abstract The purpose of this paper is to gain an understanding about what alcohol is‚ how alcohol is produced‚ the metabolic processes involved with the breakdown of alcohol in the body and the enzymes that catalyze these reactions and how these biochemical reactions affect the liver and brain and the effects of alcohol on the human body. Introduction A good deal of the population consume alcohol‚ some more than others. The effects of alcohol consumption on the human body affects mainly the

(SG) because Max’s SG is 1.035 which is within normal range. It is also not protein because in the lab manual it says that a trace amount of albumin in Max’s urine is normal. 3. If ADH levels increase‚ water reabsorption by the DCT/collecting ducts increases and the resulting urine excreted is concentrated. 4. Max’s ADH levels are the highest immediately after exercise. The reason for this is because the color of his urine is dark yellow. According to the lab manual‚ concentrated urine can be observed

Hyper & Hypopituitarism Introduction Hyperpituitarism is the result of excess secretion of adenohypophyseal trophic hormones. Hypopituitarism is the decreased secretion of one or more of the pituitary hormones. If there is decreased secretion of most pituitary hormones‚ this condition is called panhypopituitarism (pan meaning "all"). Historical Background The pituitary was known by Galen‚ and various theories were proposed about its role in the body. In the late 19th century‚ acromegaly
