Since you did not give a list of choices,here are some reasons why l<span>iving cells cannot use heat to provide the activation energy for biochemical reactions:

>Heat can never be used to do work. 
>Heat is not readily available to all living cells. 
>Heat doesn't provide the activation energy for their reactions.
        
                    
             
        
        
        
Medications can be tested on cell cultures instead of being injected into patients unnecessarily.
Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells.
 
        
                    
             
        
        
        
This is a issue of morality and ethics. So the answer to the first question depends on the perspective of the person. Personally I don't agree with performance enhancing drug use but I do think some of the expectations of athletes who perform in Olympic events increase the pressure to have to use them. So do I think people who use these drugs should be elected into the Hall of Fame. That is hard to answer. But I do not think using drugs takes away all of the achievement an athlete has made. It just proves that the athlete couldn't achieve the rigid sport performance without manipulation. But it doesn't mean they haven't worked hard or trained. 
I do think rules should be made for athletes. These rules would definitely weave through most of the athletes we see doing these out of the world sport records every day. That is because many of them have been proven to have used these performance enhancing drugs.
