The role of the ocean change with respect to the amount of carbon dioxide in the atmosphere because oceans plays a role of regulator and balancer. When there is high amount of carbon dioxide in the atmosphere due to burning of fossil fuels and volcanic eruptions so the ocean absorb that extra amount of carbon dioxide from the atmosphere while on the other hand, when there is decrease in the concentration of carbon dioxide in the atmosphere, the ocean gives its carbondioxide gas to the atmosphere to regulate the concentration.
Your friend will talk about the definition of evolutionary medicine, and there by understanding the health and diseases
Explanation:
Evolutionary medicine is the understanding the health and diseases using the evolutionary theory
Evolutionary theory gives an idea of the heritable and morphological changes in the organism.
Today, the field of research on evolutionary medicine is advanced to the molecular and psychological mechanism of health and diseases.
Hence, your friend will talk about the evolutionary understanding of the health and diseases from the lens of the evolution of species. To create an understanding of the evolutionary medicines there need to ab understanding of the heath and diseases of previous ages.
Precipitation differences are the factor that does not contribute to "water stress" on the Earth.
<u>Explanation:</u>
Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.
The cytosolic and mitochondrial pools of CoA are kept separate, and no radioactive CoA from the cytosolic pool enters the mitochondrion.
Explanation:
Fatty acyl group condensed with CoA in the cytosol are first transferred to carnitine and in this process, CoA is released.
After this, it is transported into the mitochondrion, where it is again condensed with CoA.
In this way, the cytosolic and mitochondrial pools of CoA are kept separate, and due to this reason, no radioactive CoA from the cytosolic pool enters the mitochondrion.
Therefore, according to the given question, the C14 CoA that is added into the liver homogenate along with palmitate shows cytosolic radioactive fraction but not mitochondrial as in the mitochondria a different CoA joins palmitate and not the one containing C14.
