Answer:
A represents photosynthesis and B represents cellular respiration.
Explanation:
As in A there is utilization of carbon dioxide and water to make oxygen and glucose which is a key process of photosynthesis, and then this oxygen and glucose is used as energy source to produce carbon dioxide and water as by products of respiration.
The correct answer is: c. An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.
Operons contain cluster of genes that are transcribed together into mRNA or are not expressed at all. Formed mRNA undergos splicing to create monocistronic mRNAs so that can be translated separately. Operons are more often found in prokaryotic cells but it can appear in eukaryotic cells and in viruses.
