Legumes have the ability to fix nitrogen from the atmosphere. They do this through a symbiotic relationship with nitrogen-fixing bacteria called rhizobia. These bacteria live within nodules in their root systems, and produce nitrogen compounds that the legume uses too grow.
        
             
        
        
        
The process of meiosis increases genetic variability as it produces gametes for sexual reproduction.
<span>Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.</span>
        
                    
             
        
        
        
Answer:
The water soluble hormones affect the target cells with least amount of interaction. 
Explanation:
Hormones are the chemical messengers. These are the substances secreted by the endocrine glands. The hormones are secreted directly into the bloodstream and are carried to the target cells within the blood only.  
Based on their structure, hormones are water-soluble or lipid-soluble. The lipid-soluble hormones are steroid hormones and thyroid hormones. These hormones can easily pass through the lipid bilayer of the cell membrane of the target cell. Therefore, the lipid-soluble hormones have intracellular receptors that are present in either cytoplasm or the nucleus of the target cells.  
On the other hand, the water-soluble hormones can not pass through the lipid bilayer of the target cells. Therefore, these hormones have extracellular receptors on the surface of the target cells. Binding of the water-soluble hormones to their cell surface receptors triggers the production of the intracellular second messengers that finally carry the signal to the target protein or any other target molecule. 
<u>Therefore, a water-soluble hormone exhibits the least amount of interaction with the target cell. Amine hormones such as epinephrine and melatonin, peptide hormones such as oxytocin are some examples of the water-soluble hormones.  </u>
 
        
             
        
        
        
Enzymes actually catalyses the chemical reaction so as function as catalyst.
