Water exists in all three physical states only on planet earth, the only planet where life exists in the whole of universe. Water supports life on earth due its unique physical properties such as density, temperature variation, reflectivity, surface tension, specific heat, boiling and freezing points, as well as its chemical properties including its polar nature, dissolving ability and capacity to act both as an acid or base. The exceptional physical properties are all attributed to water’s…

List three differential diagnoses for epigastric pain in adults. Include rationale, diagnostic testing, and treatment. Epigastric is the pain that comes on the upper middle portion of the abdomen.

The cereal products became so successful that in 1902 the name of the enterprise was changed to the Ralston-Purina Company. From 1902 to 1986 the…

when it comes into contact with a substance. 4. During a flood, the labels from three bottles of chemicals were lost. The three unlabeled bottles of white solids were known to contain the following substances: strontium nitrate, ammonium carbonate, and potassium sulfate. Explain in great detail how you could easily test the substances and re-label the three bottles. (Hint: Ammonium ions do not provide a distinctive flame color). To easily test the substances and re-label the three…

Early detection and diagnosis of chronic disease is of vital importance in the development of an effective treatment plan. Typical diagnostic methodology involves a multistep approach consisting of a differential diagnosis, pattern recognition, and a final clinical component. The lengthy process must be completed before any treatment options are considered often resulting in over/under diagnosis, error, and lag-time. It would be of great benefit to develop a more effective system to heighten the…

Starfish are classified under the domain Eukarya. Their multicellular presence and existing nuclei exclude them from prokaryotic domains. Furthermore, they are classified in the Animalia kingdom because they are not prokaryotes or protists. Next, Sea Stars fall under echinoderms, which are invertebrates characterized by their hard, spiny skin. The echinoderm phylum consists of mostly sea creatures (Pawson & Miller, 2016). Organisms placed in the Asteroidea class are identified by their arms that…

Cavities Many question come to mind when you hear the word cavity. Many may ask: How do I get a cavity? How long does it take for a cavity to form? How did I get this cavity?. But first what is a cavity? A cavity is formed when your tooth starts to fall apart and break down. Once you get a cavity there is no turning back. A cavity in fact can even progress and get worse. A cavity is formed when the bacteria such as plaque sits on your tooth for a period of time. What is plaque? Plaque is a…
