Answer:
This scale of evolution occurs above the level of the species. Fossils provide evidence for evolution at this scale. The evolution of the horse family. Micro evolution is evolutionary change within a species or small group of organisms, especially over a short period. And Macro evolution is major evolutionary change. The term applies mainly to the evolution of whole taxonomic groups over long periods of time.
Explanation:
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.
False
Should be the right answer because we can see mutations in humans can kill some and do nothing to others
Answer:A: the correct order is DACB
C: the correct order is ABCD
