Ground water usually contains carbonic acid
        
                    
             
        
        
        
Experimenting. Experimenting is used in all three main branches of science, physics, chemistry, and biology, and is used in all the sub-branches of science, like marine biology, to make discoveries. Without experimenting, all we know about science would be random guesses.
        
             
        
        
        
Homologous evolution means divergent evolution.
it is a type of evolution in which different species have common ancestor. for example if we take members of one species and put them in different environments then it is observed that there is some changes in the species according to environment 
analogues evolution means convergent evolution
 
        
                    
             
        
        
        
     They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)
     If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)
Have a nice day!
