Ions and organisms
(25 marks)
An organism is any living thing. There be numerous types of organisms, which are grouped into Kingdoms and eventually Species.
An ion is a charged species; it is either positively or negatively charged, and it can be any element from the periodic table, for instance, the chloride ion, Cl-, or the sodium ion, Na+.
In this essay the processes including various ions related to the organisms in the ingraft and Animal Kingdoms will be explored.
Cholera is a affection which affects humans, it was examined in BIOL1. The cholera bacterium produces a toxin that affects the chloride ion exchange in the small intestine. Firstly, the toxin causes the chloride ion passs of the epithelial cell plasma membranes in the small intestine to open. This opening causes chloride ions to rush through the ion channel from the epithelial cell into the lumen of the small intestine. Since to a greater extent and more chloride ions move into the lumen, the Cl- ion concentration in the lumen increases, leading to a decrease in piddle voltage of the lumen. This water potence change causes water from the blood to move across the epithelial cells into the lumen of the small intestine by osmosis. This water bm is quite rapid, in order to increase the water possible of the lumen.
The massive water secretion results in extreme diarrhoea, cause the body to become extremely dehydrated.
In many cases, oddly cases in developing countries, an Oral Rehydration Solution (ORS) is used as treatment to replace the lost fluid. An ORS is water which has dissolved salts, much(prenominal) as Na+ and Cl-, and dissolved sugars, such as glucose and sucrose.
Plants go for specialised cells which aid the efficient absorption of water and mineral ions. This was examined in BIOL2.
Root hair cells allow the absorption of water due to the difference in ion concentrations and hence water potential between the soil and roots. Water moves from a higher water...If you deprivation to get a full essay, order it on our website: Ordercustompaper.com
