C i am guessing but i hope this helps
The sequence of amino acid in polypeptide is dictated by the codons in the messenger RNA molecules from which polypeptide was translated. The sequence of codons in the mRNA was in turn dictated by the sequence of codons in the DNA from which the mRNA was transcribed. The amino acids are linked covalently by peptide bonds.
Answer:
During the day, plants produce (oxygen) by splitting water molecules in the light-dependent reactions of photosynthesis. At the same time, plants use cellular respiration to produce some of the (carbon dioxide) needed by the light-independent reactions to make sugars. During the night, plants produce (carbon dioxide, but not oxygen) because (only cellular respiration) takes place.
Explanation:
I will try to explain you, why is this the correct answer. During the night, there is only cellular respiration. Let me give you equation to understand the concept better. The equation of cellular respiration is: C₆H₁₂O₆ + 6O₂ + 6H₂O -> 6CO₂ + 12H₂O + ATP (energy) .. During the cellular respiration, the organism is making carbon dioxide, water and energy from glucose and oxygen. The plants are using oxygen during the night and making carbon dioxide.
