Answer:
I'm not really certain about this but my answer would be (a)
Answer:
There is a need to transform the accumulation of acetyl-CoA into the ketone bodies, as one knows that acetyl-CoA is both labile and possess an enormous amount of energy. Hence, acetyl-CoA due to its unstable characteristic is not ideal for circulation within the tissues, and at the same time, the compound acetyl-CoA does not possess the tendency to pass through the cell membrane.
Due to these reasons, the conversion of acetyl-CoA into the ketone bodies is done, the ketone bodies also act as an alternative source of energy. The ketone bodies work as water-soluble correspondents of fatty acids. The production of ketone bodies generally takes place within the liver cells' mitochondrial matrix. The three forms of ketone bodies are beta-hydroxybutyrate, acetoacetate, and acetone.
The production of ketone bodies by the liver cells helps the cells of the brain at the time of starvation, as the brain cannot use fatty acids as an energy source, as the fatty acids cannot pass through the blood-brain barrier.
Answer:
Nowadays, if a cell cannot express the AURKA gene, malignant neoplasms or cellular malignancies can be generated.
since it is related to the KRAS gene.
There is some scientific evidence or research that maintains that FOSL1 acts on another gene, AURKA, whose expression to date was thought to be independently regulated by the KRAS oncogene, and for which clinical trials are currently underway with a drug that inhibits it. .
Explanation:
Aurora kinase A also known as serine / threonine-protein kinase 6 is an enzyme that in humans is encoded by the AURKA gene.
Answer:
C. It is driven by natural processes like rock weathering and nitrogen fixation.
Explanation:
It has been discovered that eutrophication occurs through a gradual increase in the deposition of phosphorus and nitrogen and other plants nutrients in the water bodies.
This will allow the maximum growth of algae on the surface of the water.
It has been discovered that eutrophication is not good for the water bodies. This is because, the excess growth of algae on the surface of the water will prevent the sunlight from penetrating the water, thereby preventing the plants inside the water from making use of the sunlight to carryout photosynthesis. Also, it will prevent oxygen from entering, thereby depriving the organisms in the water from having the necessary oxygen needed for respiration.
Predators and prey are both in a constant struggle for survival, foxes with bigger ears tend to catch more mice, and live longer, because of this, foxes with smaller ears don't live as long, pretty soon all foxes have larger ears. The same goes for prey, Mice with padded feet live longer due to the foxes having more trouble hearing them, pretty soon all mice have padded feet, and the cycle continues.
