Answer:
The oxygen atoms of CO2 originated from glucose and the oxygen atom of H2O is originated from normal oxygen molecule that act as reactant during the break down of glucose by oxidation.
Explanation:
C6H12O6+6O2=6CO2+6H2O+Energy
In the above reaction glucose is being reduced to generate CO2 .As a result the oxygen of CO2 is originated from glucose.
The above also deals with the reduction of oxygen to H2O.From that point of view it can be stated that the oxygen atom of H2O originates from molecular oxygen that act as reactant.
Answer:
DNA does contain all genetic information within an organism I believe?
They need to be cut or cleaved by restriction enzymes called endonucleases in a way that both source and vector are left with complementary DNA strands for ligation using DNA ligase enzymes
They are Exosphere,Thermosphere,Mesosphere,Startosphere and Troposphere
