The smallest fragments of DNA will be witnessed near the bottom of the gel, on the other hand, the heavier fragments will be visible at the top. The theory behind this is there is a specific pore size on the basis of the concentration of acrylamide/agarose in the gel.
 
        
             
        
        
        
Answer: Cellular transport independent of ATP like osmosis and difussion (Simple and facilitated).
Explanation: The animal affected has a mitochondrial disease that affects its capacity of ATP production, thus, the animal active transport will be afected since require ATP. On the contrary, the animal passive transport will be functional because its independent of ATP, like osmosis which is water transport in favor of concentration gradient and facilitated diffussion of small molecules.
