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:
DNA replication is important because without it, cell division could not occur. With DNA replication, the set of DNA of a cell can be duplicated and then each cell that results from division can have its own entire set of DNA, and cell division can theoretically continue indefinitely.
The day before or the day after.
Considering the child's age and symptoms, it appears that this is an allergic reaction. It can be inferred that among the options, the food most likely to trigger these symptoms is peanut butter.
Peanut butter, in addition to having added sugar, hydrogenated or semi-hydrogenated fats, sodium and other additives, has proteins that our bodies recognize as "foreign" causing our immune system to react.
Peanut allergy is usually discovered in the early years of life, due to its high consumption in childhood, and especially affects babies and children who have asthma, rhinitis and sinus problems.
