MMT stands for Manual Muscle Testing. In this test, the muscle disorders are examined such as muscle weakness or paralysis. It is a part of physical therapy where it is important to test both the left and right side to assess the physical strength of the muscles of a patient. 
        
             
        
        
        
2. High birth rate, zero death rate, high immigration, zero emigration
This is because birth rate and immigration increase population size, and death rate and emigration decrease population size, so maximizing the former and minimizing the latter are ideal
        
                    
             
        
        
        
<span>Basically both operate by bouncing tiny particles or waves off of objects in order to make them visible. Electrons are smaller than light photons so we can see smaller objects clearly with electron microscopes. There are disadvantages though. First, color is a function of light wave frequency so we can't see electron micrographs in color. Color can be added artificially though by computer to differentiate structures, (think photoshop). Also, we cannot see electrons so we make them visible by bouncing them off a cathode ray screen similar to a TV set or computer monitor</span>
