Biosphere, relatively thin life-supporting stratum of Earth's surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean.
Answer:
A limiting factor is anything in an environment/ecosystem that limits a population's size. They can be anything from the amount of available food, shelter, and competition.
The use of a thermophilic DNA polymerase such as Taq polymerase prevents the denaturation of the enzyme during the heating that is important to separate the newly synthesized strand. So using this enzyme simplifies the PCR technique and increases its efficiency.
Taq DNA polymerase is highly efficient, when it reaches the optimum temperature, it becomes fully functional. It also has a half-life of over two hours (at 92°C), high amplification capacity, and it can add upto 150 nucleotides per second. It is "special" enzyme because it comes from the bacterium Thermus aquaticus, which lives in hot springs. It is therefore thermostable even at high temperatures, while other polymerases (e.g. E. coli) are not.

Answer:
During cellular respiration, glucose, in the presence of oxygen, is converted into carbon dioxide and water. During this process, the energy stored in glucose is transferred to ATP. Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule.
