The bottom of the sea is lined with calcium carbonate, which comes from the shells of zooplankton that have died and sunk to the ocean floor. ... As a result, according to a study published recently in PNAS, parts of the seafloor are disintegrating.
Blood reticulocyte counts provide information regarding rate of erythrocyte formation.
Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
Answer:
Cyanide is considered a specific neurotoxin and is often associated with high levels of cellular calcium and inhibition of antioxidants, leading to the formation of reactive oxygen species (ROS) and consequent lipid peroxidation. But cyanide toxicity is mainly due to the iron (Fe (III) or Fe3 +) iron binding of the mitochondrial cytochrome oxidase enzyme of the electron transport chain. This enzyme mediates the transfer of electrons to molecular oxygen
. By blocking this enzyme, the cell is unable to use oxygen and uses an anaerobic metabolism reducing pyruvate to lactic acid (lactic fermentation), which results in tissue anoxia and the rapid development of lactic acidosis. There is also a change in cell metabolism as there is a depletion in energy production. So it causes cell death. This would be the mechanism to kill cancer cells. Although, cyanide cant be use to treat cancer because it kills all the cells (leading to death) and not only the cancer cells.
Explanation:
Some researchers founded that cyanide poison may have the role of being a powerful cancer fighter. It believes that they can relate the enzyme to cancer by looking for antibodies that can recognize a protein found only in certain cancers. The method would produce an agent that could potentially kill cancer cells and leave undamaged tissue healthy.
As for the deadly nature of cyanide, scientists say the amount produced by this technique iwould be sufficient only to kill the cancer target cell by a combined enzyme and antibody molecule. And a natural enzyme produced in the human liver could detoxify any cyanide that could escape the tumor. Although, cyanide is a drug that, even if ingest a small amount, could lead to death. Some studies are going on, but until now, theres no safety of taking cyanide to treat cancer cells.
