The statement above is true. Plants contribute to precipitation through the process of transpiration. This is because this process is a naturally occurring behavior of plants where water evaporates from the plants' leaves that are carried through plants from the roots.
        
                    
             
        
        
        
Answer:
Polymyxin because, it inserts into the cell membrane and disrupts homeostasis.
Explanation:
Antimicrobial effect reacts with the cell membrane of the gram negative bacteria and causes disruption in their cell membrane by creating pores.
The cell membrane of bacteria release endotoxin for creating defense mechanism.
But the effect of certain antimicrobial peptide disrupt the effect of membrane by releasing electrostatic interaction and creates membrane pores.
The interaction between the microbial peptide and the cell membrane causes disruption of the cell.
Thus polymyxin is used to treat against the gram negative bacteria as they breaks the cell membrane of the bacteria.
