The correct answer is d. 3.5 billion years.
Prokaryotes were the first forms of life on Earth long before simple multicellular life appeared because of their ability to withstand extreme conditions. It is believed that the first living forms were bacteria combined with archaea in the microbial mat (multi-layered sheet).
 
        
                    
             
        
        
        
Mammals are adapted to live in D - all of the above. Mammals are, infact, very versatile groups of species which have evolved in a way that also itself enables their versatility. For this reason, mammals have been able to roam the different parts of Earth and thrive in that environment. 
        
                    
             
        
        
        
Answer:
The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.
Explanation:
Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.
When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe  if any splash self before washing.
Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.
