Answer:
False.
Explanation:
NADP does not  convert  testosterone to estradiol. This oxidation  is done by a steroid   17-a-hydroxysteroid dehydrogenase.
This oxidation  is essential for stability of hormone: it helps to regulates the elevation of Testosterone in women,subduing the manifestation of male sexual characteristics,
and 
for preventing autoimmune diseases.
<u>The oxidation involved two basic  steps of  reaction, controlled by two different enzymes.</u>
 
<u>NADP is a Co- factor,  when in reduced form( NADPH) is used in Calvin cycle, of light independent reaction of photosynthesis, and in Nucleic acid and triglycerides synthesis</u>. 
It has nothing to do with conversation of Androgen( testosterone  to Estradiol.
  
        
             
        
        
        
B. Because a physical reaction is a change that can be seen. This particular situation is happening over a period of time, it isn’t something that happens instantly. Also I it would have been a chemical reaction, it would have mentioned something about the state of an element or the temperature or something along those lines.
        
                    
             
        
        
        
Answer:
Commensalism
Explanation:
Commensalism is a type of relationship between two living organisms in which one organism benefits from the other without harming it. A commensal species benefits from another species by obtaining locomotion, shelter, food, or support from the host species, which (for the most part) neither benefits nor is harmed.
