Answer:
Law of conservation  of energy is one of the basic laws of the Physics. 
Explanation:
According to the Law of conservation of energy, the total energy of an isolated system doesn't change, Energy may be transformed from one to another but the total energy of an isolated system remains constant.    There have different forms of energy like- kinetic energy, potential energy, chemical energy, thermal energy , electrical energy. the potential energy is converting into kinetic energy in the water falls. When kicking a football, energy is transferred from the body of the kicker to the ball. 
 
        
                    
             
        
        
        
It is called <span>semiconservative replication.</span>
        
             
        
        
        
<span>Refraction happens when there</span> is a bending of path of a light wave as it
passes across the boundary separating two media and the degree of bending is
determined in part by the total change in velocity as the light<span> passes from one medium to the other. In
addition, the change in speed experienced by a
wave when it changes medium can result in a number of beautiful optical effects. </span>
 
        
             
        
        
        
Answer:
Blood cells are produced in the bone marrow of the body more specifically they become blood cells from first being stem cells which then divide until they reach a mature red blood cell stage. ( or other types of cells, stem cells are like the blank template for either red blood cells, white blood cells, or platelettes.)
