Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.
Answer:
E. Gene is amplified by multiplication of cloning host
Explanation:
PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.
As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.
Answer:
B. Plants in the desert would have a decreased number of stomata compared to rainforest plants.
Answer:
Explanation:
After having a carbohydrate rich meal concentration of some hormones, especially insulin change in your body. Insulin promotes the uptake of glucose by cells(particularly muscle cells, adipocytes, liver cells). It also increases the rate of glycolysis and glycogenesis and decreases the rate of gluconeogenesis and glycogenolysis.
These important metabolic pathways cause burning up glucose to make ATP that all cells in our body need and also storing it in the form of glycogen in the liver which is a very important food storage. Metabolism of carbohydrates also causes fat to be deposited in adipocytes which is basically why we have stuff like keto diets(no or very little carbohydrates and mainly fats consumed) for losing weight!
