Answer:
Taq DNA polymerase is an enzyme which can withstand the high temperature as it is resistance to heat therefore is heat stable. This enzyme plays an important role in Polymerase chain reaction as a procedure requires high temperature.
The enzyme was originally isolated from a thermophilic bacterium named <em>Thermus aquaticus</em> near the Lower Geyser Basin of Yellowstone National Park. The Taq word was adapted from the name of the bacteria as<em> T</em><em>hermus </em><em>aq</em><em>uaticus </em>= Taq and polymerase as it poylmerizes the DNA.

Answer:
carbon dioxide and water (hydrogen dioxide)
Explanation:
the plant breaks both compounds down into their elements, puts the oxygen back into the atmosphere as waste, and uses the carbon and hydrogen to make glucose through phosynthesis through use of sunlight
A chemical change is a change in which the composition of the matter is changed at the molecular level, most chemical changes are not easily irreversible, for example, an egg being cooked, the egg changes from its liquid like state to a solid, and it is not possible to revert it back to its original change. The egg itself is changed in this case.
A physical change on the other hand however, is only changing the substance of a matter, not its composition, this is usually easily reversible. For example, water turning into ice, the water's substance changed from its liquid state to its solid state, it is still water, and it can easily be turned back into water by heating it.
Sorry for the long explanation,
Hope this helps!
