Answer:
I may be wrong but try A.
The chemical formula C6H12O6 is the chemical formula of glucose which is a monosaccharide containing an aldehyde group (-CHO) with 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. Glucose is a product produced from photosynthesis.
The chemical molecular formula for the photosynthesis process is 6CO2+6H2O→C6H12O6+6O2. The synthesis process is a reaction that occurs in plants to produce food to be used as energy for cells. The process of photosynthesis requires materials in the form of air which is represented by H2O and carbon dioxide which is represented by the formula CO2 in the chemical formula of the photosynthesis process. The products of photosynthesis are glucose which is represented by C6H12O6 and oxygen which is represented by O2 in the chemical formula.
Some people often refer to the chemical formula of photosynthesis as CO2+H2O→C6H12O6+O2, this formula is an unbalanced equation. Because the auction will produce glucose with the chemical formula C6H12O6 having 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms, then should the chemical formula carbon dioxide H2O and water O2 also have a total of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

Answer: A
Explanation:The Trp operon is responsible for synthesis of the amino acid trytophan when it is not available in the cellular environment.
When the tryptophan is plentiful, a repressor protein binds to two molecules of tryptophan.
Thiss repressor-tryptophan complex binds to the trp operator. This binding prevents the binding of RNA polymerase, so the operon is not transcribed, and no new trptophan is produce.
On the other hand, when tryptophan levels are reduced, the inactive repressor will not bind the tryptophan operator so the operon is transcribed.
Regulation of the trp operon is determined by the concentration of tryptophan; when adequate tryptophan is present in the growth medium, there is no need for tryptophan biosynthesis.
Transcription is turned off when a high concentration of tryptophan is present, and is turned on when tryptophan is absent. The regulatory signal is the concentration of tryptophan itself.
Therefore in the absence of tryptophan, the inactive repressor cannot bind trpO, so operon gene transcription occurs.
