Per calendar year (365 days) there are 31536000 seconds
The answer should be Groundwater.
Unicellular organism are one celled but multicellular organisms are made up of many cells.
<h3>Explain the difference between unicellular and multicellular organization of organisms? </h3>
As the name suggests, unicellular organisms are made up of only one cell and this single cell carries out all the essential functions that are needed for the survival of the organism like respiration, photosynthesis etc.
But in multicellular organization, the organisms are made of more than one cells and cells are grouped according to their functions. Each group is specialized for specific functions. Even in higher multicellular organisms the group of cells form specific types of tissues and further they form organs and organ systems which function more efficiently.
Thus, this is the difference.

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.
Answer:
a) Protective effect on the health or incidence of disease (low-fat diet and colon cancer)
b) No association between exposure and incidence of disease for health (aerobic exercise and dental caries)
c) Positive association between the incidence of disease and the exposure (exposure to side-stream cigarette smoke and lung cancer)
d) Positive association between the incidence of disease and the exposure (infectious disease of the pelvis and ectopic (tubal) pregnancy).
Explanation:
The interpretation of OR can measure the association between the frequency of exposure and health in a sample that is considered statistically significant. When the OR is equal to 1, it means that there is no association between exposure and an incidence of health disease. When the OR is equal to 0.5, it means that the exposure has a protective effect on the incidence of the disease on health. And finally, when the OR is above to 1, it means that there is a positive association between the incidence of the disease and the exposure.
a) OR = +0.6. Since this value is less than 1 but greater than 0.5, it means that the exposure has a protective effect on the health or incidence of the disease.
b) OR = +1.0. As in this case, the OR value is equal to 1, meaning that there is no association between exposure and the incidence of disease for health.
c) OR = +1.3. As in this case the value is greater than 1, it means that there is a positive association between the incidence of the disease and the exposure.
d) OR = +3.0. There is a positive association between the incidence of the disease and the exposure. The OR 3 value means that the incidence of the disease and the health result will be three higher in people who are exposed.
