Answer:
True.
Explanation:
Enkephalins and endorphins are endogenous peptides while morphine is an exogenous peptide.
Enkephalins and endorphins are powerful analgesics 18 to 500 times more than morphine. Hence, morphine is less analgesic than enkephalins and endorphins.
Enkephalins and endorphins act on the  mu, kappa , delta receptors and morphine also acts on the same receptors. All of them has same effects on the body.
Hence, Enkephalins and endorphins are peptides that act like morphine.
 
        
                    
             
        
        
        
These preparations are called Vaccines. A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.
        
                    
             
        
        
        
The correct answer for the question is B, ATP contains less potential energy than ADP.
Explanation;
ATP contains more energy potential than ADP , since it has three phosphate bonds unlike ADP which has 2 phosphates.
A. is true; During glycolysis ATP is formed, Glycolysis uses 2 ATP molecules and also generates four ATP molecules which gives a net energy of 2 ATP molecules.
C is true, as plant cells generate ATP during cellular respiration. Cellular respiration is the process in which cells generate energy in form of ATP through oxidative phosphorylation in the mitochondria. 
D. is true; ATP is used as a mobile energy carrier molecule by all cells. It used by these cells to fuel all cellular activities. 
        
                    
             
        
        
        
The hydrosphere is defined as the water surrounding the surface of globe include oceans lakes etc
The statement that is not correct about hydrosphere is
Most of the water making up the hydrosphere is in lakes
because its not lakes its oceans
so correct option is B
hope it helps
