intrinsic
Explanation:
Proteins are dynamic molecules that are capable of INTRINSIC motion that can have important functional relevance. The existence of this type of motion has suggested that enzymes are capable - even in the absence of substrate - of many of the same movements that can be detected during their catalytic cycle
 
        
             
        
        
        
Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.
        
             
        
        
        
Answer:
Protozoans can be parasitic. Malaria is the most significant of the protozoan parasites that infect humans. Malaria is found in tropical and sub-tropical regions of the world. In addition, tropical countries are often affected by poverty, poor sanitation, and inadequate medical facilities. These factors often increase the transmission of parasitic diseases.
