Answer:
Mercuric particles is the right answer  
Pseudomonas has a plasmid containing the mer operon that incorporates a quality for mercuric reductase catalyzing mercuric particle to an uncharged type of mercury. The inducer is mercuric particles.
 
        
             
        
        
        
Answer:
The correct answer will be option- Glycolysis. 
Explanation:
Gluconeogenesis is a metabolic pathway which synthesizes glucose from non-sugar precursors. This pathway is activated in the low concentration of glucose due to less intake or completely absent to conserve energy.
This pathway is somewhat the reverse of the glycolysis when excess energy is present as a result of glycolysis, gluconeogenesis is inhibited and when no energy is present, gluconeogenesis is activated.
Thus, option- glycolysis is the correct answer.
