Answer:
free molecules; plasma membrane
Explanation:
-Venom are complex mixtures of molecules called "toxins" 
-Plasma membrane is the membrane found in cells that separates the interior of the cell from the outside environment 
 
        
             
        
        
        
the insertion on removal of mutations are dangerous in nature.  the process is basically just one large gamble to see what it does. and even though we have a decent understanding of the genomes of many animals and plants, we still dont know everything. so if we tamper with certain genes we may cause a evolution or we might kill the subject and the potential for it to procreate.

Salt molecules are much smaller than starch molecules and can pass through more easily. ... Thus, they are quite large molecules in contrast to the relatively small salt molecules. The smaller salt molecules pass through the membrane easily, but the larger starch molecules cannot pass through the membrane.
