Through leaching. B horizons or subsoil get materials from above through accumulated rain water that leached these materials and precipitated it into the B horizon.
Answer:
Thus, during the Citric Acid cycle, the breakdown of glucose into carbon dioxide is completed. There are four redox reactions, three of which yield reduced NADH and one FADH2. Thus, the oxidation of glucose is completed in the Kreb's cycle
Answer:
Structure of DNA provides basic information about its packing, replication and copying of the stored genetic information. It tells how the parent DNA strands are copied during the process of cell division.
Explanation:
The double-helical structure of DNA is the basis for its ability to store the genetic information, to replicate itself and to transmit the genetic information. DNA is a polymer of four nucleotides. It stores the genetic information in the sequence of these four nucleotides. The complementary base pairing between the DNA bases tells how DNA template strands are copied during the process of replication.
The newly formed DNA strands have complementary nucleotide sequence to the template DNA strands. Similarly, during the transmission of genetic information, the nucleotide sequence of the DNA is copied into the nucleotide sequence of the mRNA. Therefore, knowledge about the structure of DNA is required to understand its functions.
Extraction of aluminium metal takes place in three main stages¿mining of bauxite ore, refining the ore to recover alumina and smelting alumina to produce aluminium. Bauxite is mined by surface methods (open-cut mining) in which the topsoil and overburden are removed by bulldozers and scrapers.
They compete by food source because they both eat bugs and there for compete on who gets the bugs.
