Answer:
a. the coordinated control of gene expression in bacteria
Explanation:
An operon in bacteria is a collection/cluster of genes that are under the control of a single promoter. It includes 3 components: a promoter, the genes and an operator. The operator is where a repressor binds, and the promoter is where transcription begins.
Operons allow organisms to control the expression of multiple genes in response to environmental cues
an increase in atmospheric carbon dioxide
Answer: D
In photosynthesis o2 is released while in cellular respiration o2 is taken.
Photosynthesis occur in the presence of sunlight while cellular respiration has no boundations
Both require o2.
Both leads to the formation of new substance.
It is a reduction of number of cells of their parent cell in half equal numbers.
