(D) It uses enzymes to liquefy food and kill bacteria to be further digested in the intestines.
 
        
             
        
        
        
The answer would be D.nucleus, prokaryotic cells don’t have a nucleus instead their dna floats around inside the cell

The heat can cause the killing of the bacteria. It is estimated that all the pathogenic bacteria are killed after a heating of 70-75 degree Celsius or 165 degree Fahrenheit. 
The ground meat or poultry can be infected from many type of bacteria, which are present in atmosphere or in the body of the organism, whose meat is being consumed.
So, in order to kill the pathogenic bacteria, the cooking at 165 degree Fahrenheit or above for sometime must be done
So, the given blank can be filled with 165.
