Calcium

The ocean is a vast vista of blossoming life and mysterious wonders that lurk in the deep. Our exquisite ocean is being ravaged through a process known as ocean acidification. Ocean acidification is the process of carbon dioxide and numerous gases being absorbed into the ocean, which raises the ocean’s pH, causing it to become more acidic. Contrary to popular belief, terrestrial vegetation does not intake all of the carbon dioxide in the atmosphere. The ocean absorbs about fifty-percent of…

(Sr) and it has atomic number of 38. It is an alkaline earth metal, and is a soft white yellowish metallic element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons. The electron configuration of Strontium is 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(10) 4s^(2) 4p^(6) 5s^(2) or…

Shewanella putrefaciens is naturally found in the environment all throughout nature, but are commonly found within soil or within a water environment. Shewanella putrefaciens has only been isolated from such clinical materials as various body wounds, feces, conjunctiva, urine, CSF, bile, ascitic fluid, pleural fluid, and stored blood. Putrefaciens has been isolated from fish, chicken,meat, fresh and salt water. The major risk factor of S. putrefaciens infection is hepatobiliary disease,…

2012, p. 1097) In acute renal failure myoglobin precipitates in the tubules obstructing the flow through the nephrons and causing injury. Damage to the myocyte causes an influx of sodium into the cell and cytosolic calcium accumulation due to direct injury to the cell. The high calcium concentration has a number of dangerous effects including the activation of phospholipase A2 which results in toxic metabolites and cell death. Large…

genetic mutations, and the increase of age are all factors that contribute to the development of the disease. Although Parkinson’s disease is incurable, treatment can ease the symptoms. Treatments that block calcium channels may moderate the progression of the disease, because a large amount of calcium can kill dopamine neurons and inhibit the normal function of the cell signaling pathway. A “normal” cell signaling pathway has three major steps;…

potential to affect coral (focus on individual coral colony) Ocean acidification alters a range of marine ecosystems by damaging foundation organisms, such as living corals. Coral contains calcium carbonate, a mineral that is used to form the supporting skeletal structures found in many marine organisms (2 ). Calcium…

Not Much Value in Vitamins Every year, Americans spend tens of billions of dollars on purchasing vitamin supplements (“A challenge to Vitamins”). You many wonder, are vitamins still worth buying? According to Dr. Fortmann, an epidemiologist, those who buy vitamins may be just throwing their money away. One of the main problems of vitamins is that people believe vitamins will give them all the nutrients their body needs for the day. Overdosing on vitamins, another issue, can lead to damage…

polycystin 2, and integral membrane protein with homology to the voltage- activated sodium and calcium a1 channels” (Thompson & Thompson, 2007). The PKD2 gene makes the protein polycystin-2, which is regulated by polycystin-1. When polycystin-1 interacts with polycystin-2 it instructs the cell to undergo chemical reactions inside the cell. Polycystin-2 channels the transportation of charged atoms, and calcium ions in…

obtained. In the first three trials, Calcium Chloride was the limiting reagent and in the last trial Sodium carbonate was the limiting reagent. The moles of CaCO3 produced for each trial was 0.0008113moles, 0.001188 moles, 0.0004476 moles and 0.0002907moles respectively. The mass of product measured for each trial was 0.0812g, 0.1189g,…

peanut oil because peanuts yield an acid, thus they contain acid-ash. Acid-ash residue is inorganic radicals that form acid ions in the body, causing lower pH making the urine more acidic. Acid urine favors the excretion of kidney stones consisting of calcium and magnesium phosphates, carbonates, and oxalates. It also enhances the effect of some medications used for urinary tract infections. So it can boost the effects of something used against bacteria, but can it kill/prevent bacteria growth…
