Explanation:
Yes, this is true because some bacteria in our environment tends to either fend off of or kill other types of bacteria. In this case, this bacteria is helpful because it turns gaseous nitrogen into a form that can be absorbed and used by plants in our environment.
 
        
             
        
        
        
Answer:
NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.
Explanation:
NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.
              NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.
           Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.
               That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get  low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.
 
        
             
        
        
        
The answers are photosynthesis, respiration, decomposition, natural rock weathering and fossil fuel combustion.
        
             
        
        
        
Answer:
The answer would be D. 3,360
Explanation:
The solution is found by multiplying 16 times 15 times 14. The club has 16 members and after one role (president) is filled, there are 15 left to fill the next (vice). The same goes for the next role (treasurer). So 16 is multiplied with 15, then 14. This is more of a math question that biology btw.
